Nabumetone



Class: Other Nonsteroidal Anti-inflammatory Agents
Chemical Name: 4-(6-Methoxy-2-naphthyl)-2-butanone
Molecular Formula: C15H16O2
CAS Number: 42924-53-8


  • Cardiovascular Risk


  • Possible increased risk of serious (sometimes fatal) cardiovascular thrombotic events (e.g., MI, stroke).1 Risk may increase with duration of use.1 Individuals with cardiovascular disease or risk factors for cardiovascular disease may be at increased risk.1 (See Cardiovascular Effects under Cautions.)




  • Contraindicated for the treatment of pain in the setting of CABG surgery.1



  • GI Risk


  • Increased risk of serious (sometimes fatal) GI events (e.g., bleeding, ulceration, perforation of the stomach or intestine).1 Serious GI events can occur at any time and may not be preceded by warning signs and symptoms.1 Geriatric individuals are at greater risk for serious GI events.1 (See GI Effects under Cautions.)




Introduction

Prototypical NSAIA;1 prodrug with little pharmacologic activity until oxidized in the liver to form an active metabolite that is structurally similar to naproxen.1 2 3


Uses for Nabumetone


Consider potential benefits and risks of nabumetone therapy as well as alternative therapies before initiating therapy with the drug.1 Use lowest effective dosage and shortest duration of therapy consistent with the patient’s treatment goals.1


Inflammatory Diseases


Symptomatic treatment of osteoarthritis and rheumatoid arthritis.1


Nabumetone Dosage and Administration


General



  • Consider potential benefits and risks of nabumetone therapy as well as alternative therapies before initiating therapy with the drug.1



Administration


Oral Administration


Administer orally once or twice daily without regard to meals.1


Dosage


To minimize the potential risk of adverse cardiovascular and/or GI events, use lowest effective dosage and shortest duration of therapy consistent with the patient’s treatment goals.1 Adjust dosage based on individual requirements and response; attempt to titrate to the lowest effective dosage.1


Adults


Inflammatory Diseases

Osteoarthritis or Rheumatoid Arthritis

Oral

Initially, 1 g once daily.1 May increase dosage to 1.5–2 g daily, given as a single daily dose or 2 divided doses.1


Patients weighing <50 kg may be less likely to need dosages >1 g daily.1


Prescribing Limits


Adults


Inflammatory Diseases

Osteoarthritis or Rheumatoid Arthritis

Oral

Maximum 2 g daily.1


Special Populations


Renal Impairment


Dosage adjustment not necessary in patients with mild renal impairment (Clcr >50 mL/minute).1


In patients with moderate renal impairment (Clcr 30–49 mL/minute), initiate at ≤750 mg daily (maximum initial dosage is 750 mg daily).1 Monitor renal function; may increase dosage to 1.5 g daily.1


In patients with severe renal impairment (Clcr <30 mL/minute), initiate at ≤500 mg daily (maximum inital dosage is 500 mg daily).1 Monitor renal function; may increase dosage to 1 g daily.1


Cautions for Nabumetone


Contraindications



  • Known hypersensitivity to nabumetone or any ingredient in the formulation.1




  • History of asthma, urticaria, or other sensitivity reaction precipitated by aspirin or other NSAIAs.1 2




  • Treatment of perioperative pain in the setting of CABG surgery.1



Warnings/Precautions


Warnings


Cardiovascular Effects

Selective COX-2 inhibitors have been associated with an increased risk of serious adverse cardiovascular thrombotic events in certain situations.1 Several prototypical NSAIAs also have been associated with an increased risk of cardiovascular events.4 5 6 Current data insufficient to assess risk associated with nabumetone.4 5 6


Use NSAIAs with caution and careful monitoring (e.g., monitor for development of cardiovascular events), and at the lowest effective dosage for the shortest duration necessary.1


Short-term use to relieve acute pain, especially at low dosages, does not appear to be associated with increased risk of serious cardiovascular events (except immediately following CABG surgery).a


No consistent evidence that concomitant use of low-dose aspirin mitigates the increased risk of serious adverse cardiovascular events associated with NSAIAs.1 (See Specific Drugs under Interactions.)


Hypertension and worsening of preexisting hypertension reported; either event may contribute to the increased incidence of cardiovascular events.1 Use with caution in patients with hypertension; monitor BP.1 Impaired response to certain diuretics may occur.1 (See Specific Drugs under Interactions.)


Fluid retention and edema reported.1 Caution in patients with fluid retention or heart failure.1


GI Effects

Serious GI toxicity (e.g., bleeding, ulceration, perforation) can occur with or without warning symptoms; increased risk in those with a history of GI bleeding or ulceration, geriatric patients, smokers, those with alcohol dependence, and those in poor general health.1


For patients at high risk for complications from NSAIA-induced GI ulceration (e.g., bleeding, perforation), consider concomitant use of misoprostol; alternatively, consider concomitant use of a proton-pump inhibitor (e.g., omeprazole) or use of an NSAIA that is a selective inhibitor of COX-2 (e.g., celecoxib).


Renal Effects

Direct renal injury, including renal papillary necrosis, reported in patients receiving long-term NSAIA therapy.1


Potential for overt renal decompensation.1 Increased risk of renal toxicity in patients with renal or hepatic impairment or heart failure, in patients with volume depletion, in geriatric patients, and in those receiving a diuretic, ACE inhibitor, or angiotensin II receptor antagonist.1 c (See Renal Impairment under Cautions.)


Sensitivity Reactions


Hypersensitivity Reactions

Anaphylactoid reactions reported.1


Immediate medical intervention and discontinuance for anaphylaxis.1


Avoid in patients with aspirin triad (aspirin sensitivity, asthma, nasal polyps); caution in patients with asthma.1


Dermatologic Reactions

Serious skin reactions (e.g., exfoliative dermatitis, Stevens-Johnson syndrome, toxic epidermal necrolysis) reported; can occur without warning.1 Discontinue at first appearance of rash or any other sign of hypersensitivity (e.g., blisters, fever, pruritus).1


Photosensitivity Reactions

Photosensitivity reactions possible.1


General Precautions


Hepatic Effects

Severe reactions including jaundice, fatal fulminant hepatitis, liver necrosis, and hepatic failure (sometimes fatal) reported rarely with NSAIAs.1


Elevations of serum ALT or AST reported.1


Monitor for symptoms and/or signs suggesting liver dysfunction; monitor abnormal liver function test results.1 Discontinue if signs or symptoms of liver disease or systemic manifestations (e.g., eosinophilia, rash) occur or if liver function test abnormalities persist or worsen.1


Hematologic Effects

Anemia reported rarely.1 Determine hemoglobin concentration or hematocrit in patients receiving long-term therapy if signs or symptoms of anemia occur.1


May inhibit platelet aggregation and prolong bleeding time.1


Other Precautions

Not a substitute for corticosteroid therapy; not effective in the management of adrenal insufficiency.1


May mask certain signs of infection.1


Obtain CBC and chemistry profile periodically during long-term use.1


Specific Populations


Pregnancy

Category C.1 Avoid use in third trimester because of possible premature closure of the ductus arteriosus.1


Lactation

Active metabolite is distributed into milk in rats; not known whether nabumetone or its metabolites are distributed into milk in humans.1 Discontinue nursing or the drug.1


Pediatric Use

Safety and efficacy not established in children.1


Geriatric Use

Caution advised.1 Safety and efficacy profiles similar to those in younger adults.1 However, fatal adverse GI effects reported more frequently in geriatric patients than in younger adults.1


Hepatic Impairment

Caution advised in patients with severe hepatic impairment, since formation of the active metabolite depends on biotransformation in the liver.1


Renal Impairment

Use with caution in patients with renal disease.1 Use not recommended in patients with advanced renal disease; close monitoring of renal function advised if used.1


Dosage adjustments necessary in patients with moderate or severe renal impairment.1 (See Renal Impairment under Dosage and Administration.)


Oxidized and conjugated metabolites that are excreted in urine may accumulate in patients with renal failure, potentially resulting in adverse effects.1


Common Adverse Effects


Abdominal pain, constipation, diarrhea, dizziness, dyspepsia, edema, flatulence, headache, nausea, positive stool guaiac test, pruritus, rash, tinnitus.1

Nabumetone Pharmacokinetics


Absorption


Bioavailability


Well absorbed following oral administration.1 Rapidly biotransformed to active metabolite, 6MNA; peak plasma concentration of 6MNA usually attained within 2.5–4 hours.1 Approximately 35% of a 1-g dose is metabolized to 6MNA.1 Unchanged nabumetone is not detected in plasma.1


Food


Food increases rate of nabumetone absorption; increases rate but not extent of metabolism to 6MNA.1


Special Populations


In geriatric patients, steady-state plasma 6MNA concentrations are higher than in younger individuals.1


Distribution


Plasma Protein Binding


6MNA: >99%.1


Elimination


Metabolism


6MNA is extensively metabolized in the liver to inactive metabolites; 6MNA does not appear to undergo enterohepatic recirculation.1


Elimination Route


Excreted mainly in urine as metabolites of 6MNA and metabolites of nabumetone.1


Half-life


6MNA: about 23–30 hours.1


Special Populations


In patients with moderate renal impairment (Clcr 30–49 mL/minute) and severe renal impairment (Clcr <30 mL/minute), elimination half-life of 6MNA increased.1


Stability


Storage


Oral


Tablets

25°C (may be exposed to 15–30°C).1


ActionsActions



  • Inhibits cyclooxygenase-1 (COX-1) and COX-2.1




  • Pharmacologic actions similar to those of other prototypical NSAIAs; exhibits anti-inflammatory, analgesic, and antipyretic activity.1

When necessary, the pH of each formula was adjusted with sodium hydroxide so that the pH of the reconstituted solution is within the USP specified range of 7 to 8.


The chemical name for hydrocortisone sodium succinate is pregn-4-ene-3,20-dione,21-(3-carboxy-1-oxopropoxy)-11,17-dihydroxy-, monosodium salt, (11β)- and its molecular weight is 484.52.


The structural formula is represented below:



Hydrocortisone sodium succinate is a white or nearly white, odorless, hygroscopic amorphous solid. It is very soluble in water and in alcohol, very slightly soluble in acetone and insoluble in chloroform.



Solu-Cortef - Clinical Pharmacology


Glucocorticoids, naturally occurring and synthetic, are adrenocortical steroids that are readily absorbed from the gastrointestinal tract.


Naturally occurring glucocorticoids (hydrocortisone and cortisone), which also have salt-retaining properties, are used as replacement therapy in adrenocortical deficiency states. Their synthetic analogs are primarily used for their anti-inflammatory effects in disorders of many organ systems.


Hydrocortisone sodium succinate has the same metabolic and anti-inflammatory actions as hydrocortisone. When given parenterally and in equimolar quantities, the two compounds are equivalent in biologic activity. The highly water-soluble sodium succinate ester of hydrocortisone permits the immediate intravenous administration of high doses of hydrocortisone in a small volume of diluent and is particularly useful where high blood levels of hydrocortisone are required rapidly. Following the intravenous injection of hydrocortisone sodium succinate, demonstrable effects are evident within one hour and persist for a variable period. Excretion of the administered dose is nearly complete within 12 hours. Thus, if constantly high blood levels are required, injections should be made every 4 to 6 hours. This preparation is also rapidly absorbed when administered intramuscularly and is excreted in a pattern similar to that observed after intravenous injection.


Glucocorticoids cause profound and varied metabolic effects. In addition, they modify the body's immune response to diverse stimuli.



Indications and Usage for Solu-Cortef


When oral therapy is not feasible, and the strength, dosage form, and route of administration of the drug reasonably lend the preparation to the treatment of the condition, the intravenous or intramusculat use of Solu-Cortef Sterile Powder is indicated as follows:



Allergic states


Control of severe or incapacitating allergic conditions intractable to adequate trials of conventional treatment in asthma, atopic dermatitis, contact dermatitis, drug hypersensitivity reactions, perennial or seasonal allergic rhinitis, serum sickness, transfusion reactions.



Dermatologic diseases


Bullous dermatitis herpetiformis, exfoliative erythroderma, mycosis fungoides, pemphigus, severe erythema multiforme (Stevens-Johnson syndrome).



Endocrine disorders


Primary or secondary adrenocortical insufficiency (hydrocortisone or cortisone is the drug of choice; synthetic analogs may be used in conjunction with mineralocorticoids where applicable; in infancy, mineralocorticoid supplementation is of particular importance), congenital adrenal hyperplasia, hypercalcemia associated with cancer, nonsuppurative thyroiditis.



Gastrointestinal diseases


To tide the patient over a critical period of the disease in regional enteritis (systemic therapy) and ulcerative colitis.



Hematologic disorders


Acquired (autoimmune) hemolytic anemia, congenital (erythroid) hypoplastic anemia (Diamond-Blackfan anemia), idiopathic thrombocytopenic purpura in adults (intravenous administration only; intramuscular administration is contraindicated), pure red cell aplasia, selected cases of secondary thrombocytopenia.



Miscellaneous


Trichinosis with neurologic or myocardial involvement, tuberculous meningitis with subarachnoid block or impending block when used concurrently with appropriate antituberculous chemotherapy.



Neoplastic diseases


For the palliative management of leukemias and lymphomas.



Nervous System


Acute exacerbations of multiple sclerosis; cerebral edema associated with primary or metastatic brain tumor, or craniotomy.



Ophthalmic diseases


Sympathetic ophthalmia, uveitis and ocular inflammatory conditions unresponsive to topical corticosteroids.



Renal diseases


To induce diuresis or remission of proteinuria in idiopathic nephrotic syndrome or that due to lupus erythematosus.



Respiratory diseases


Berylliosis, fulminating or disseminated pulmonary tuberculosis when used concurrently with appropriate antituberculous chemotherapy, idiopathic eosinophilic pneumonias, symptomatic sarcoidosis.



Rheumatic disorders


As adjunctive therapy for short-term administration (to tide the patient over an acute episode or exacerbation) in acute gouty arthritis; acute rheumatic carditis; ankylosing spondylitis; psoriatic arthritis; rheumatoid arthritis, including juvenile rheumatoid arthritis (selected cases may require low-dose maintenance therapy). For the treatment of dermatomyositis, temporal arteritis, polymyositis, and systemic lupus erythematosus.



Contraindications


Solu-Cortef Sterile Powder is contraindicated in systemic fungal infections and patients with known hypersensitivity to the product and its constituents.


Intramuscular corticosteroid preparations are contraindicated for idiopathic thrombocytopenic purpura.


Solu-Cortef Sterile Powder is contraindicated for intrathecal administration. Reports of severe medical events have been associated with this route of administration.



Warnings



General


Injection of Solu-Cortef may result in dermal and/or subdermal changes forming depressions in the skin at the injection site. In order to minimize the incidence of dermal and subdermal atrophy, care must be exercised not to exceed recommended doses in injections. Injection into the deltoid muscle should be avoided because of a high incidence of subcutaneous atrophy.


Rare instances of anaphylactoid reactions have occurred in patients receiving corticosteroid therapy (see ADVERSE REACTIONS).


Increased dosage of rapidly acting corticosteroids is indicated in patients on corticosteroid therapy subjected to any unusual stress before, during, and after the stressful situation.


Results from one multicenter, randomized, placebo-controlled study with methylprednisolone hemisuccinate, an IV corticosteroid, showed an increase in early (at 2 weeks) and late (at 6 months) mortality in patients with cranial trauma who were determined not to have other clear indications for corticosteroid treatment. High doses of systemic corticosteroids, including Solu-Cortef, should not be used for the treatment of traumatic brain injury.



Cardio-renal


Average and large doses of corticosteroids can cause elevation of blood pressure, salt and water retention, and increased excretion of potassium. These effects are less likely to occur with the synthetic derivatives except when used in large doses. Dietary salt restriction and potassium supplementation may be necessary. All corticosteroids increase calcium excretion.


Literature reports suggest an apparent association between use of corticosteroids and left ventricular free wall rupture after a recent myocardial infarction; therefore, therapy with corticosteroids should be used with great caution in these patients.



Endocrine


Hypothalamic-pituitary adrenal (HPA) axis suppression. Cushing's syndrome, and hyperglycemia. Monitor patients for these conditions with chronic use. Corticosteroids can produce reversible HPA axis suppression with the potential for glucocorticosteroid insufficiency after withdrawal of treatment. Drug induced secondary adrenocortical insufficiency may be minimized by gradual reduction of dosage. This type of relative insufficiency may persist for months after discontinuation of therapy; therefore, in any situation of stress occurring during that period, hormone therapy should be reinstituted.



Infections


General

Patients who are on corticosteroids are more susceptible to infections than are healthy individuals. There may be decreased resistance and inability to localize infection when corticosteroids are used. Infection with any pathogen (viral, bacterial, fungal, protozoan or helminthic) in any location of the body may be associated with the use of corticosteroids alone or in combination with other immunosuppressive agents.


These infections may be mild, but can be severe and at times fatal. With increasing doses of corticosteroids, the rate of occurrence of infectious complications increases. Corticosteroids may also mask some signs of current infection. Do not use intra-articularly, intrabursally or for intratendinous administration for local effect in the presence of acute local infection.


Fungal infections

Corticosteroids may exacerbate systemic fungal infections and therefore should not be used in the presence of such infections unless they are needed to control drug reactions. There have been cases reported in which concomitant use of amphotericin B and hydrocortisone was followed by cardiac enlargement and congestive heart failure (see CONTRAINDICATIONS and PRECAUTIONS, Drug Interactions, Amphotericin B injection and potassium-depleting agents).


Special pathogens

Latent disease may be activated or there may be an exacerbation of intercurrent infections due to pathogens, including those caused by Amoeba, Candida, Cryptococus, Mycobacterium, Nocardia, Pneumocystis, Toxoplasma.


It is recommended that latent amebiasis or active amebiasis be ruled out before initiating corticosteroid therapy in any patient who has spent time in the tropics or in any patient with unexplained diarrhea.


Similarly, corticosteroids should be used with great care in patients with known or suspected Strongyloides (threadworm) infestation. In such patients, corticosteroid-induced immunosuppression may lead to Strongyloides hyperinfection and dissemination with widespread larval migration, often accompanied by severe enterocolitis and potentially fatal gram-negative septicemia.


Corticosteroids should not be used in cerebral malaria. There is currently no evidence of benefit from steroids in this condition.


Tuberculosis

The use of corticosteroids in active tuberculosis should be restricted to those cases of fulminating or disseminated tuberculosis in which the corticosteroid is used for the management of the disease in conjunction with an appropriate antituberculous regimen.


If corticosteroids are indicated in patients with latent tuberculosis or tuberculin reactivity, close observation is necessary as reactivation of the disease may occur. During prolonged corticosteroid therapy, these patients should receive chemoprophylaxis.


Vaccination

Administration of live or live, attenuated vaccines is contraindicated in patients receiving immunosuppressive doses of corticosteroids. Killed or inactivated vaccines may be administered. However, the reponse to such vaccines cannot be predicted. Immunization procedures may be undertaken in patients who are receiving corticosteroids as replacement therapy, e.g., for Addison's disease.


Viral infections

Chicken pox and measles can have a more serious or even fatal course in pediatric and adult patients on corticosteroids. In pediatric and adult patients who have not had these diseases, particular care should be taken to avoid exposure. The contribution of the underlying disease and/or prior corticosteroid treatment to the risk is also not known. If exposed to chicken pox, prophylaxis with varicella zoster immune globulin (VZIG) may be indicated. If exposed to measles, prophylaxis with immunoglobulin (IG) may be indicated. (See the respective package inserts for complete VZIG and IG prescribing information.) If chicken pox develops, treatment with antiviral agents should be considered.


Neurologic

Reports of severe medical events have been associated with the intrathecal route of administration (see ADVERSE REACTIONS, Neurologic/Psychiatric).


Ophthalmic

Use of corticosteroids may produce posterior subcapsular cataracts, glaucoma with possible damage to the optic nerves, and may enhance the establishment of secondary ocular infections due to bacteria, fungi, or viruses. The use of oral corticosteroids is not recommended in the treatment of optic neuritis and may lead to an increase in the risk of new episodes. Corticosteroids should be used cautiously in patients with ocular herpes simplex because of corneal perforation. Corticosteroids should not be used in active ocular herpes simplex.



Precautions



General


This product, like many other steroid formulations, is sensitive to heat. Therefore, it should not be autoclaved when it is desirable to sterilize the exterior of the vial. The lowest possible dose of corticosteroid should be used to control the condition under treatment. When reduction in dosage is possible, the reduction should be gradual.


Since complications of treatment with glucocorticoids are dependent on the size of the dose and the duration of treatment, a risk/benefit decision must be made in each individual case as to dose and duration of treatment and as to whether daily or intermittent therapy should be used.


Kaposi's sarcoma has been reported to occur in patients receiving corticosteroid therapy, most often for chronic conditions. Discontinuation of corticosteroids may result in clinical improvement.



Cardio-renal


As sodium retention with resultant edema and potassium loss may occur in patients receiving corticosteroids, these agents should be used with caution in patients with congestive heart failure, hypertension, or renal insufficiency.



Endocrine


Drug-induced secondary adrenocortical insufficiency may be minimized by gradual reduction of dosage. This type of relative insufficiency may persist for months after discontinuation of therapy; therefore, in any situation of stress occurring during that period, hormone therapy should be reinstituted. Since mineralocorticoid secretion may be impaired, salt and/or a mineralocorticoid should be administered concurrently. Metabolic clearance of corticosteroids is decreased in hypothyroid patients and increased in hyperthyroid patients. Changes in thyroid status of the patient may necessitate adjustment in dosage.



Gastrointestinal


Steroids should be used with caution in active or latent peptic ulcers, diverticulitis, fresh intestinal anastomoses, and nonspecific ulcerative colitis, since they may increase the risk of a perforation. Signs of peritoneal irritation following gastrointestinal perforation in patients receiving corticosteroids may be minimal or absent.


There is an enhanced effect due to increased metabolism of corticosteroids in patients with cirrhosis.



Musculoskeletal


Corticosteroids decrease bone formation and increase bone resorption both through their effect on calcium regulation (i.e., decreasing absorption and increasing excretion) and inhibition of osteoblast function. This, together with a decrease in the protein matrix of the bone secondary to an increase in protein catabolism, and reduced sex hormone production, may lead to inhibition of bone growth in pediatric patients and the development of osteoporosis at any age. Special consideration should be given to patients at increased risk of osteoporosis (i.e., postmenopausal women) before initiating corticosteroid therapy.


Local injection of a steroid into a previously infected site is not usually recommended.



Neurologic-psychiatric


Although controlled clinical trials have shown corticosteroids to be effective in speeding the resolution of acute exacerbations of multiple sclerosis, they do not show that they affect the ultimate outcome or natural history of the disease. The studies do show that relatively high doses of corticosteroids are necessary to demonstrate a significant effect. (See DOSAGE AND ADMINISTRATION.)


An acute myopathy has been observed with the use of high doses of corticosteroids, most often occurring in patients with disorders of neuromuscular transmission (e.g., myasthenia gravis), or in patients receiving concomitant therapy with neuromuscular blocking drugs (e.g., pancuronium). This acute myopathy is generalized, may involve ocular and respiratory muscles, and may result in quadriparesis. Elevation of creatinine kinase may occur. Clinical improvement or recovery after stopping corticosteroids may require weeks to years.


Psychic derangements may appear when corticosteroids are used, ranging from euphoria, insomnia, mood swings, personality changes, and severe depression to frank psychotic manifestations. Also, existing emotional instability or psychotic tendencies may be aggravated by corticosteroids.



Ophthalmic


Intraocular pressure may become elevated in some individuals. If steroid therapy is continued for more than 6 weeks, intraocular pressure should be monitored.



Information for Patients


Patients should be warned not to discontinue the use of corticosteroids abruptly or without medical supervision, to advise any medical attendants that they are taking corticosteroids and to seek medical advice at once should they develop fever or other signs of infection.


Persons who are on corticosteroids should be warned to avoid exposure to chicken pox or measles. Patients should also be advised that if they are exposed, medical advice should be sought without delay.



Drug Interactions


Aminoglutethimide

Aminoglutethimide may lead to a loss of corticosteroid-induced adrenal suppression.


Amphotericin B injection and potassium-depleting agents

When corticosteroids are administered concomitantly with potassium-depleting agents (i.e., amphotericin-B, diuretics), patients should be observed closely for development of hypokalemia. There have been cases reported in which concomitant use of amphotericin B and hydrocortisone was followed by cardiac enlargement and congestive heart failure.


Antibiotics

Macrolide antibiotics have been reported to cause a significant decrease in corticosteroid clearance (see Drug Interactions, Hepatic Enzyme Inhibitors).


Anticholinesterases

Concomitant use of anticholinesterase agents and corticosteroids may produce severe weakness in patients with myasthenia gravis. If possible, anticholinesterase agents should be withdrawn at least 24 hours before initiating corticosteroid therapy.


Anticoagulants, oral

Coadministration of corticosteroids and warfarin usually results in inhibition of response to warfarin, although there have been some conflicting reports. Therefore, coagulation indices should be monitored frequently to maintain the desired anticoagulant effect.


Antidiabetics

Because corticosteroids may increase blood glucose concentrations, dosage adjustments of antidiabetic agents may be required.


Antitubercular drugs

Serum concentrations of isoniazid may be decreased.


Cholestyramine

Cholestyramine may increase the clearance of corticosteroids.


Cyclosporine

Increased activity of both cyclosporine and corticosteroids may occur when the two are used concurrently. Convulsions have been reported with this concurrent use.


Digitalis glycosides

Patients on digitalis glycosides may be at increased risk of arrhythmias due to hypokalemia.


Estrogens, including oral contraceptives

Estrogens may decrease the hepatic metabolism of certain corticosteroids, thereby increasing their effect.


Hepatic Enzyme Inducers (e.g., barbiturates, phenytoin, carbamazepine, rifampin)

Drugs which induce cytochrome P450 3A4 enzyme activity may enhance the metabolism of corticosteroids and require that the dosage of the corticosteroid be increased.


Hepatic Enzyme Inhibitors (e.g., ketoconazole, macrolide antibiotics such as erythromycin and troleandomycin)

Drugs which inhibit cytochrome P450 3A4 have the potential to result in increased plasma concentrations of corticosteroids.


Ketoconazole

Ketoconazole has been reported to significantly decrease the metabolism of certain corticosteroids by up to 60%, leading to an increased risk of corticosteroid side effects.


Nonsteroidal anti-inflammatory agents (NSAIDs)

Concomitant use of aspirin (or other nonsteroidal anti-inflammatory agents) and corticosteroids increases the risk of gastrointestinal side effects. Aspirin should be used cautiously in conjunction with corticosteroids in hypoprothrombinemia. The clearance of salicylates may be increased with concurrent use of corticosteroids.


Skin tests

Corticosteroids may suppress reactions to skin tests.


Vaccines

Patients on prolonged corticosteroid therapy may exhibit a diminished response to toxoids and live or inactivated vaccines due to inhibition of antibody response. Corticosteroids may also potentiate the replication of some organisms contained in live attenuated vaccines. Routine administration of vaccines or toxoids should be deferred until corticosteroid therapy is discontinued if possible (see WARNINGS, Infections, Vaccination).



Carcinogenesis, Mutagenesis, Impairment of Fertility


No adequate studies have been conducted in animals to determine whether corticosteroids have a potential for carcinogenesis or mutagenesis.


Steroids may increase or decrease motility and number of spermatozoa in some patients.



Pregnancy


Teratogenic effects

Pregnancy Category C


Corticosteroids have been shown to be teratogenic in many species when given in doses equivalent to the human dose. Animal studies in which corticosteroids have been given to pregnant mice, rats, and rabbits have yielded an increased incidence of cleft palate in the offspring. There are no adequate and well-controlled studies in pregnant women. Corticosteroids should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Infants born to mothers who have received corticosteroids during pregnancy should be carefully observed for signs of hypoadrenalism.



Nursing Mothers


Systemically administered corticosteroids appear in human milk and could suppress growth, interfere with endogenous corticosteroid production, or cause other untoward effects. Because of the potential for serious adverse reactions in nursing infants from corticosteroids, a decision should be made whether to continue nursing, or discontinue the drug, taking into account the importance of the drug to the mother.



Pediatric Use


The efficacy and safety of corticosteroids in the pediatric population are based on the well-established course of effect of corticosteroids which is similar in pediatric and adult populations. Published studies provide evidence of efficacy and safety in pediatric patients for the treatment of nephrotic syndrome (>2 years of age), and aggressive lymphomas and leukemias (>1 month of age). Other indications for pediatric use of corticosteroids, e.g., severe asthma and wheezing, are based on adequate and well-controlled trials conducted in adults, on the premises that the course of the diseases and their pathophysiology are considered to be substantially similar in both populations.


The adverse effects of corticosteroids in pediatric patients are similar to those in adults (see ADVERSE REACTIONS). Like adults, pediatric patients should be carefully observed with frequent measurements of blood pressure, weight, height, intraocular pressure, and clinical evaluation for the presence of infection, psychosocial disturbances, thromboembolism, peptic ulcers, cataracts, and osteoporosis. Pediatric patients who are treated with corticosteroids by any route, including systemically administered corticosteroids, may experience a decrease in their growth velocity. This negative impact of corticosteroids on growth has been observed at low systemic doses and in the absence of laboratory evidence of HPA axis suppression (i.e., cosyntropin stimulation and basal cortisol plasma levels). Growth velocity may therefore be a more sensitive indicator of systemic corticosteroid exposure in pediatric patients than some commonly used tests of HPA axis function. The linear growth of pediatric patients treated with corticosteroids should be monitored, and the potential growth effects of prolonged treatment should be weighed against clinical benefits obtained and the availability of treatment alternatives. In order to minimize the potential growth effects of corticosteroids, pediatric patients should be titrated to the lowest effective dose.



Geriatric Use


Clinical studies did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.



Adverse Reactions


The following adverse reactions have been reported with Solu-Cortef or other corticosteroids:


Allergic reactions: Allergic or hypersensitivity reactions, anaphylactoid reaction, anaphylaxis, angioedema.

Musculoskeletal: Aseptic necrosis of femoral and humeral heads, Charcot-like arthropathy, loss of muscle mass, muscle weakness, osteoporosis, pathologic fracture of long bones, postinjection flare (following intra-articular use), steroid myopathy, tendon rupture, vertebral compression fractures.


Neurologic/Psychiatric: Convulsions, depression, emotional instability, euphoria, headache, increased intracranial pressure with papilledema (pseudotumor cerebri) usually following discontinuation of treatment, insomnia, mood swings, neuritis, neuropathy, paresthesia, personality changes, psychic disorders, vertigo. Arachnoiditis, meningitis, paraparesis/paraplegia, and sensory disturbances have occurred after intrathecal administration (see WARNINGS, Neurologic).


Ophthalmic: Exophthalmoses, glaucoma, increased intraocular pressure, posterior subcapsular cataracts, rare instances of blindness associated with periocular injections.


Other: Abnormal fat deposits, decreased resistance to infection, hiccups, increased or decreased motility and number of spermatozoa, injection site infections following non-sterile administration (see WARNINGS), malaise, moon face, weight gain.



Overdosage


Treatment of acute overdosage is by supportive and symptomatic therapy. For chronic overdosage in the face of severe disease requiring continuous steroid therapy, the dosage of the corticosteroid may be reduced only temporarily, or alternate day treatment may be introduced.



Solu-Cortef Dosage and Administration


Because of possible physical incompatilitbilites, Solu-Cortef should not be diluted or mixed with other solutions.


Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.


This preparation may be administered by intravenous injection, by intravenous infusion, or by intramuscular injection, the preferred method for initial emergency use being intravenous injection. Following the initial emergency period, consideration should be given to employing a longer acting injectable preparation or an oral preparation.


Therapy is initiated by administering Solu-Cortef Sterile Powder intravenously over a period of 30 seconds (e.g., 100 mg) to 10 minutes (e.g., 500 mg or more). In general, high dose corticosteroid therapy should be continued only until the patient's condition has stabilized-usually not beyond 48 to 72 hours. When high dose hydrocortisone therapy must be continued beyond 48–72 hours, hypernatremia may occur. Under such circumstances it may be desirable to replace Solu-Cortef with a corticoid such as methylprednisolone sodium succinate which causes little or no sodium retention.


The initial dose of Solu-Cortef Sterile Powder is 100 mg to 500 mg, depending on the specific disease entity being treated. However, in certain overwhelming, acute, life-threatening situations, administration in dosages exceeding the usual dosages may be justified and may be in multiples of the oral dosages.


This dose may be repeated at intervals of 2, 4 or 6 hours as indicated by the patient's response and clinical condition.


It Should Be Emphasized that Dosage Requirements are Variable and Must Be Individualized on the Basis of the Disease Under Treatment and the Response of the Patient. After a favorable response is noted, the proper maintenance dosage should be determined by decreasing the initial drug dosage in small decrements at appropriate time intervals until the lowest dosage that maintains an adequate clinical response is reached. Situations which may make dosage adjustments necessary are changes in clinical status secondary to remissions or exacerbations in the disease process, the patient's individual drug responsiveness, and the effect of patient exposure to stressful situations not directly related to the disease entity under treatment. In this latter situation it may be necessary to increase the dosage of the corticosteroid for a period of time consistent with the patient's condition. If after long-term therapy the drug is to be stopped, it is recommended that it be withdrawn gradually rather than abruptly.


In the treatment of acute exacerbations of multiple sclerosis, daily doses of 800 mg of hydrocortisone for a week followed by 320 mg every other day for one month are recommended (see PRECAUTIONS, Neuro-psychiatric).


In pediatric patients, the initial dose of hydrocortisone may vary depending on the specific disease entity being treated. The range of initial doses is 0.56 to 8 mg/kg/day in three or four divided doses (20 to 240 mg/m2bsa/day). For the purpose of comparison, the following is the equivalent milligram dosage of the various glucocorticoids:












Cortisone, 25Triamcinolone, 4
Hydrocortisone, 20Paramethasone, 2
Prednisolone, 5Betamethasone, 0.75
Prednisone, 5Dexamethasone, 0.75
Methylprednisolone, 4

These dose relationships apply only to oral or intravenous administration of these compounds. When these substances or their derivatives intramuscularly or into joint spaces, their relative properties may be greatly altered.



Preparation of Solutions 100 mg Plain


For intravenous or intramuscular injection, prepare solution by aseptically adding not more than 2 mL of Bacteriostatic Water for Injection or Bacteriostatic Sodium Chloride Injection to the contents of one vial. For intravenous infusion, first prepare solution by adding not more than 2 mL of Bacteriostatic Water for Injection to the vial; this solution may then be added to 100 to 1000 mL of the following: 5% dextrose in water (or isotonic saline solution or 5% dextrose in isotonic saline solution if patient is not on sodium restriction).



DIRECTIONS FOR USING THE ACT-O-VIAL SYSTEM


  1. Press down on plastic activator to force diluent into the lower compartment.

  2. Gently agitate to effect solution.

  3. Remove plastic tab covering center of stopper.

  4. Sterilize top of stopper with a suitable germicide.

  5. Insert needle squarely through center of stopper until tip is just visible. Invert vial and withdraw dose.


Further dilution is not necessary for intravenous or intramuscular injection. For intravenous infusion, first prepare solution as just described. The 100 mg solution may then be added to 100 to 1000 mL of 5% dextrose in water (or isotonic saline solution or 5% dextrose in isotonic saline solution if patient is not on sodium restriction). The 250 mg solution may be added to 250 to 1000 mL, the 500 mg solution may be added to 500 to 1000 mL and the 1000 mg solution to 1000 mL of the same diluents. In cases where administration of a small volume of fluid is desirable, 100 mg to 3000 mg of Solu-Cortef may be added to 50 mL of the above diluents. The resulting solutions are stable for at least 4 hours and may be administered either directly or by IV piggyback.


When reconstituted as directed, pH's of the solutions range from 7 to 8 and the tonicities are: 100 mg ACT-O-VIAL, .36 osmolar; 250 mg ACT-O-VIAL, 500 mg ACT-O-VIAL, and the 1000 mg ACT-O-VIAL, .57 osmolar. (Isotonic saline=.28 osmolar.)

Maraviroc


Pronunciation: MAR-a-VIR-ok
Generic Name: Maraviroc
Brand Name: Selzentry

Liver problems have been reported in some patients taking Maraviroc. An allergic reaction may occur before liver problems develop. Contact your doctor right away if you develop a rash; hives; itching; trouble breathing; tightness in the chest; swelling of the mouth, face, lips, or tongue; yellowing of the eyes or skin; dark urine; pale stools; loss of appetite; or severe stomach pain.





Maraviroc is used for:

Treating patients with a certain type of HIV infection (CCR5-tropic HIV-1). It is used along with other HIV medicines.


Maraviroc is a CCR5 coreceptor antagonist. It works by blocking the virus from entering cells.


Do NOT use Maraviroc if:


  • you are allergic to any ingredient in Maraviroc

  • you are taking St. John's wort

  • you have severe kidney problems or you are on dialysis and you take certain other medicines. Talk to your doctor before taking Maraviroc if you have kidney problems

Contact your doctor or health care provider right away if any of these apply to you.



Before using Maraviroc:


Some medical conditions may interact with Maraviroc. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:


  • if you are pregnant, planning to become pregnant, or are breast-feeding

  • if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement

  • if you have allergies to medicines, foods, or other substances

  • if you have a history of liver problems, hepatitis B or C, heart or kidney problems, or if you are at risk of heart problems

  • if you are on dialysis

  • if you have a history of low blood pressure or dizziness when you stand up

  • if you are taking medicine to lower your blood pressure

Some MEDICINES MAY INTERACT with Maraviroc. Tell your health care provider if you are taking any other medicines, especially any of the following:


  • Azole antifungals (eg, itraconazole, ketoconazole), delavirdine, ketolides (eg, telithromycin), macrolides (eg, clarithromycin), nefazodone, or protease inhibitors (eg, amprenavir, boceprevir, ritonavir) because they may increase the risk of Maraviroc's side effects

  • Barbiturates (eg, phenobarbital), carbamazepine, efavirenz, etravirine, hydantoins (eg, phenytoin), rifamycins (eg, rifampin), or St. John's wort because they may decrease Maraviroc's effectiveness

This may not be a complete list of all interactions that may occur. Ask your health care provider if Maraviroc may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.


How to use Maraviroc:


Use Maraviroc as directed by your doctor. Check the label on the medicine for exact dosing instructions.


  • Maraviroc comes with an extra patient information sheet called a Medication Guide. Read it carefully. Read it again each time you get Maraviroc refilled.

  • Take Maraviroc by mouth with or without food.

  • Swallow Maraviroc whole. Do not break, crush, or chew before swallowing.

  • Taking Maraviroc at the same time each day will help you remember to take it.

  • Continue to take Maraviroc even if you feel well. Do not miss any doses.

  • If you miss a dose of Maraviroc, take it as soon as possible. If your next dose is less than 6 hours away, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

Ask your health care provider any questions you may have about how to use Maraviroc.



Important safety information:


  • Maraviroc may cause dizziness. This effect may be worse if you take it with alcohol or certain medicines. Use Maraviroc with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.

  • Maraviroc may cause dizziness, light-headedness, or fainting; alcohol, hot weather, exercise, or fever may increase these effects. Your risk may be greater if you have severe kidney problems. To prevent them, sit up or stand slowly, especially in the morning. Sit or lie down at the first sign of any of these effects.

  • Do NOT take more than the recommended dose or use more often than prescribed without checking with your doctor.

  • Certain other medicines for HIV (eg, HIV protease inhibitors, delavirdine, efavirenz) may increase the side effects of Maraviroc or decrease its effectiveness. Talk with your doctor about all of your HIV medicines. Do not start, stop, or change the dose of any HIV medicine unless your doctor tells you to.

  • Maraviroc may improve immune system function. This may reveal hidden infections in some patients. Tell your doctor right away if you notice symptoms of infection (eg, fever, sore throat, weakness, cough, shortness of breath) after you start Maraviroc.

  • Maraviroc may increase the risk of developing an infection. Avoid contact with people who have colds or infections. Tell your doctor if you notice signs of infection like fever, sore throat, rash, or chills. Discuss any questions or concerns with your doctor.

  • It is possible that Maraviroc may increase the risk of developing cancer. No increase in cancer cases has been seen in patients who take Maraviroc. Discuss any questions or concerns with your doctor.

  • Maraviroc is not a cure for HIV infection. Patients may still get illnesses and infections associated with HIV. Remain under the care of your doctor.

  • When your medicine supply is low, get more from your doctor or pharmacist as soon as you can. Do not stop taking Maraviroc, even for a short period of time. If you do, the virus may grow resistant to the medicine and become harder to treat.

  • Maraviroc does not stop the spread of HIV to others through blood or sexual contact. Use barrier methods of birth control (eg, condoms) if you have HIV infection. Do not share needles, injection supplies, or items like toothbrushes or razors.

  • Lab tests, including liver function, may be performed while you use Maraviroc. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.

  • Use Maraviroc with caution in the ELDERLY; they may be more sensitive to its effects.

  • Maraviroc should not be used in CHILDREN younger than 16 years old; safety and effectiveness in these children have not been confirmed.

  • PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using Maraviroc while you are pregnant. It is not known if Maraviroc is found in breast milk. Mothers infected with HIV should not breast-feed. There is a risk of passing the HIV infection or Maraviroc to the baby.


Possible side effects of Maraviroc:


All medicines may cause side effects, but many people have no, or minor, side effects. Check with your doctor if any of these most COMMON side effects persist or become bothersome:
