Dosage and administration

Standard tests for verification of adrenal responsiveness to corticotropin may utilize as much as 80 units as a single injection or one or more injections of a lesser dosage. Verification tests should be performed prior to treatment with corticotropins. The test should utilize the route(s) of administration proposed for treatment. Following verification dosage should be individualized according to the disease under treatment and the general medical condition of each patient. Frequency and dose of the drug should be determined by considering severity of the disease, plasma and urine corticosteroid levels and the initial response of the patient. Only gradual change in dosage schedules should be attempted, after full drug effects have become apparent. This product may be administered subcutaneously or intramuscularly with the vial and subcutaneously with the prefilled syringe. In the treatment of acute exacerbations of multiple sclerosis daily subcutaneous or intramuscular doses of 80-120 units for 2-3 weeks. The chronic administration of more than 40 units daily may be associated with uncontrollable adverse effects. When reduction in dosage is indicated this should be accomplished gradually by either reducing the amount of each injection, or administering injections at longer intervals, or by a combination of both of the above. During reduction of dosage, careful consideration should be given to the disease being treated, the general medical condition of the patient and the duration over which corticotropin was administered. Important Administration Instructions
• Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. Purified Cortrophin Gel is a clear, light amber liquid gel at room temperature. Do not use if the solution is discolored or cloudy or the solution contains particulate matter.
• Purified Cortrophin Gel will be a solid gel when refrigerated and needs to be warmed to a liquid gel before administration. o For Purified Cortrophin Gel vials warm by rolling between your hands for a few minutes. o For Purified Cortrophin Gel prefilled syringes remove the carton from the refrigerator and leave at room temperature for 45 minutes.
• The recommended injection sites include abdomen, upper thigh, or upper arm. Do not inject within 2 inches of navel. Information for Patients Advise patients and/or caregivers to read the FDA-approved patient information (Instructions for Use).

Contraindications

Purified Cortrophin Gel is contraindicated for intravenous administration. Purified Cortrophin Gel is contraindicated in patients with scleroderma, osteoporosis, systemic fungal infections, ocular herpes simplex, recent surgery, history of or the presence of a peptic ulcer, congestive heart failure, hypertension, or sensitivity to proteins derived from porcine sources. Purified Cortrophin Gel is contraindicated in patients with primary adrenocortical insufficiency or adrenocortical hyperfunction.

Warnings

Chronic administration of corticotropin may lead to adverse effects which are not reversible. This product should not be administered for treatment until adrenal responsiveness has been verified with the route of administration which will be utilized during treatment, intramuscularly or subcutaneously. A rise in urinary and plasma corticosteroid values provides direct evidence of a stimulatory effect. Although the action of corticotropin is similar to that of exogenous adrenocortical steroids the quantity of adrenocorticoid may be variable. In patients who receive prolonged corticotropin therapy the additional use of rapidly acting corticosteroids before, during and after an unusual stressful situation is indicated. Masking Symptoms of Other Diseases Corticotropin may only suppress symptoms and signs of chronic disease without altering the natural course of the disease. Immunogenicity Potential Purified Cortrophin Gel is immunogenic. Limited available data suggest that a patient may develop antibodies to Purified Cortrophin Gel after chronic administration and loss of endogenous ACTH and Purified Cortrophin Gel activity. Prolonged administration of Purified Cortrophin Gel may increase the risk of hypersensitivity reactions. Cases of anaphylaxis following administration have also been reported in the postmarketing setting. Sensitivity to porcine protein should be considered before starting therapy and during the course of treatment should symptoms arise. Ophthalmic Effects Prolonged use of corticotropin may produce posterior subcapsular cataracts and glaucoma with possible damage to the optic nerves. Infections Corticotropin may mask some signs of infection, and new infections including those of the eye due to fungi or viruses may appear during its use. There may be decreased resistance and inability to localize infection when corticotropin is used. Elevated Blood Pressure, Salt and Water Retention, and Hypokalemia Corticotropin can cause elevation of blood pressure, salt and water retention, and increased excretion of potassium. Dietary salt restriction and potassium supplementation may be necessary. Corticotropin increases calcium excretion. Vaccination While on corticotropin therapy, patients should not be vaccinated against smallpox. Other immunization procedures should be undertaken with caution in patients who are receiving corticotropin, especially when high doses are administered because of the possible hazards of neurological complications and lack of antibody response.

Precautions

General Patients with latent tuberculosis or tuberculin reactivity who receive corticotropin should be closely observed as reactivation of the disease may occur. During prolonged corticotropin therapy, these patients should receive chemoprophylaxis. Skin testing should be performed prior to treatment of all patients with suspected sensitivity to porcine protein. Immediately following intramuscular or subcutaneous administration of corticotropin all patients should be observed carefully for sensitivity reactions. Relative adrenocortical insufficiency induced by prolonged corticotropin therapy may be minimized by gradual reduction of corticotropin dosage. This type of insufficiency may persist for months after discontinuation of therapy; therefore, in any situation of stress during that period, hormone therapy should be reinstituted. There is an enhanced effect of corticotropin in patients with hypothyroidism and in those with cirrhosis. The lowest possible dosage of corticotropin should be used to control the condition under treatment, and when reduction in dosage is possible the reduction should be gradual. Corticotropin should be administered for treatment only when the disease is intractable to more conventional therapy. Corticotropin should be adjunctive and not the sole therapy in the treatment of a disease. Since maximal corticotropin stimulation of the adrenals may be limited during the first few days of treatment, other drugs should be administered when an immediate therapeutic effect is desirable. When infection is present appropriate anti-infective therapy should be administered during corticotropin and following discontinuation of corticotropin therapy. Treatment of acute gouty arthritis should be limited to a few days. Since rebound attacks may occur when corticotropin is discontinued, conventional concomitant therapy should be administered during corticotropin treatment, and for several days after it is stopped. Psychic derangements may appear when corticotropin is used, ranging from euphoria, insomnia, mood swings, personality changes, and depression, to frank psychotic manifestations. Also, existing emotional instability or psychotic tendencies may be aggravated by corticotropin. Corticotropin should be used with caution in patients with diabetes, abscess, pyogenic infections, diverticulitis, renal insufficiency, and myasthenia gravis. Growth and development of infants and children on prolonged corticotropin therapy should be carefully observed. Although controlled clinical trials have shown ACTH to be effective in speeding the resolution of acute exacerbations of multiple sclerosis, they do not show that it affects the ultimate outcome or natural history of the disease. Since complications of treatment with ACTH 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. Drug Interactions Aspirin should be used cautiously in conjunction with corticotropin in hypoprothrombinemia. Pregnancy Since fetal abnormalities have been observed in experimental animals, use of this drug in pregnancy, nursing mothers, or women of childbearing potential requires that the potential benefits of the drug be weighed against the potential hazards to the mother and embryo or fetus. Infants born of mothers who have received substantial doses of corticotropin during pregnancy should be carefully observed for signs of hypoadrenalism.
