Deltasone (Prednisone)


Pharmacia & Upjohn



Action And Clinical Pharmacology: Prednisone is a corticosteroid, which like other steroids, acts by controlling the rate of synthesis of proteins. The corticosteroids react with receptor proteins in the cytoplasm of sensitive cells to form a steroid-receptor complex. The steroid receptor complex moves into the nucleus where it binds to chromatin. Information carried by the steroid or more likely by the receptor protein directs the genetic apparatus to transcribe RNA. Steroid hormones thus stimulate transcription and ultimately the synthesis of specific proteins.

The major physiologic actions of prednisone are: to increase liver glycogen deposition and to decrease the inflammatory response. Prednisone has some effects on sodium and fluid retention.

The mechanism of action is not fully established. It is theorized that the drug’s anti-inflammatory effect is due to multiple mechanisms, including the inhibition of leukocyte migration to sites of tissue injury, the impairment of phagocytosis plus reduced capillary permeability. The drug’s immunosuppressant effect is attributed to several factors, among them a transient lymphopenia especially of T-lymphocytes, and inhibition of immunoglobulin production of monocytes.

Prednisone is rapidly and completely absorbed from the intestinal tract. After oral administration, maximum plasma concentrations are reached in 1 to 2 hours. Once absorbed, the drug is approximately 75% bound to plasma proteins. The major route of elimination is via the liver (t 1/2=4 hr.); and the active drug disappears completely in about 12 hours.

Contra-Indications: Systemic fungal infections and known hypersensitivity to prednisone or to its excipients.

Manufacturers’ Warnings In Clinical States: In patients on corticosteroid therapy subjected to unusual stress, increased dosage of rapidly acting corticosteroids before, during, and after the stressful situation is indicated.

Corticosteroids may mask some signs of infection, and new infections may appear during their use. There may be decreased resistance and inability to localize infection when corticosteroids are used. Infections with any pathogen including viral, bacterial, fungal, protozoan or helminthic infections, in any location in the body, may be associated with the use of corticosteroids alone or in combination with other immunosuppressive agents that affect cellular immunity, humoral immunity or neutrophil function. These infections may be mild, but can be severe and at times fatal. With increasing doses of corticosteroids, the rate of occurrence of infectious complication increases. Do not use intra-articularly, intrabursally, or for intratendinous administration for local effect in the presence of acute infection.

Prolonged 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 fungi or viruses. Allergic reactions (e.g. angioedema) may occur.

Average and large doses of hydrocortisone or cortisone 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.

Administration of live or live, attenuated vaccines is contra-indicated in patients receiving immunosuppressive doses of corticosteroids. Killed or inactivated vaccines may be administered to patients receiving immunosuppressive doses of corticosteroids. However the response to such vaccines may be diminished. Indicated immunization procedures may be undertaken in patients receiving nonimmunosuppressive doses of corticosteroids.

The use of prednisone 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.

There is no universal agreement on whether corticosteroids per se are responsible for peptic ulcers encountered during therapy; however, glucocorticoid therapy may mask the symptoms of peptic ulcer so that perforation or hemorrhage may occur without significant pain.

Osteoporosis is a common but infrequently recognized adverse effect associated with a long-term use of large doses of glucocorticoid.

Growth may be suppressed in children receiving long-term daily, divided dose glucocorticoid therapy and use of such regimen should be restricted to the most urgent indications. Alternate day glucocorticoid therapy usually avoids or minimizes this side effect.

Host defenses are impaired in patients receiving large doses of glucocorticoids and this effect increases susceptibility to fungus infections as well as bacterial and viral infections.

Pregnancy and Lactation: Some animal studies have shown that corticosteroids, when administered to the mother at high doses, may cause fetal malformations. Adequate human reproductive studies have not been done with corticosteroids. Therefore, the use of this drug in pregnancy, nursing mothers or women of childbearing potential requires that the benefits of the drug be carefully weighed against the potential risk to the mother and embryo or fetus. Since there is inadequate evidence of safety in human pregnancy, this drug should be used in pregnancy only if clearly needed.

Corticosteroids readily cross the placenta. Infants born of mothers who have received substantial doses of corticosteroids during pregnancy must be carefully observed and evaluated for signs of adrenal insufficiency. There are no known effects of corticosteroids on labor and delivery. Corticosteroids are excreted in breast milk.

Precautions: 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.

There is an enhanced effect of corticosteroids on patients with hypothyroidism and in those with cirrhosis.

Corticosteroids should be used cautiously in patients with ocular herpes simplex because of possible corneal perforation.

The lowest possible dose of corticosteroid should be used to control the condition under treatment and when reduction in dosage, the reduction should be gradual.

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.

ASA and nonsteroidal anti-inflammatory agents should be used cautiously in conjunction with corticosteroids in patients with hypoprothrombinemia.

Corticosteroids should be used with caution in nonspecific ulcerative colitis, if there is a probability of impending perforation, abscess or other pyogenic infection; diverticulitis; fresh intestinal anastomoses; active or latent peptic ulcer; renal insufficiency; hypertension; osteoporosis; or myasthenia gravis.

Because 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.

Convulsions have been reported with concurrent use of methylprednisolone and cyclosporine. SInce concurrent administration of these agents results in a mutual inhibition of metabolism, it is possible that convulsions and other adverse events associated with the individual use of either drug may be more apt to occur.

The possibility of this interaction occurring with prednisone should be considered.

Kaposi’s sarcoma has been reported to occur in patients receiving corticosteroid therapy. Discontinuation of corticosteroids may result in clinical remission.

Carcinogenesis, Mutagenesis, Impairment of Fertility: There is no evidence that corticosteroids are carcinogenic, mutagenic, or impair fertility.

Lactation: Some prednisone is excreted in breast milk.

Drug Interactions: The pharmacokinetic interactions listed below are potentially clinically important.

Drugs that induce hepatic enzymes such as phenobarbital, phenytoin and rifampin may increase the clearance of corticosteroids and may require increases in corticosteroid dose to achieve the desired response.

Drugs such as troleandomycin and ketoconazole may inhibit the metabolism of corticosteroids and thus decrease their clearance. Therefore, the dose of corticosteroid should be titrated to avoid steroid toxicity.

Corticosteroids may increase the clearance of chronic high dose ASA. This could lead to decreased salicylate serum levels or increase the risk of salicylate toxicity when the corticosteroid is withdrawn. ASA should be used cautiously in conjunction with corticosteroids in patients suffering from hypothrombinemia.

The effect of corticosteroids on oral anticoagulants is variable. There are reports of enhanced, as well as, diminished effects of anticoagulant when given concurrently with corticosteroids. Therefore, coagulation indices should be monitored to maintain the desired anticoagulant effect.

Adverse Reactions: Note: The following are typical for all systemic corticosteroids. Their inclusion in this list does not necessarily indicate that the specific event has been observed with this particular formulation.

Fluid and Electrolyte Disturbances: sodium retention; fluid retention; congestive heart failure in susceptible patients; potassium loss, hypokalemic alkalosis; hypertension.

Musculoskeletal: steroid myopathy; muscle weakness; osteoporosis; pathologic fractures; vertebral compression fractures; aseptic necrosis; loss of muscle mass; tendon rupture – particularly of the Achilles tendon.

Gastrointestinal: peptic ulceration with possible perforation and hemorrhage; gastric hemorrhage; pancreatitis; perforation of the bowel; abdominal distention; ulcerative esophagitis.

Increases in ALT, AST and alkaline phosphatase have been observed following corticosteroid treatment. These changes are usually small, not associated with any clinical syndrome and are reversible upon discontinuation.

Dermatologic: impaired wound healing; petechiae and ecchymoses; thin fragile skin; facial erythema; increased sweating; may suppress reactions to skin tests.

Metabolic: negative nitrogen balance due to protein catabolism.

Neurological: increased intracranial pressure with papilledema (pseudotumor cerebri); vertigo; headache; psychic derangements; seizures.

Endocrine: menstrual irregularities; development of cushingoid state; suppression of pituitary-adrenal axis; decreased carbohydrate tolerance; manifestations of latent diabetes mellitus; increased requirements for insulin or oral hypoglycemic agents in diabetes; suppression of growth in children.

Ophthalmic: posterior subcapsular cataracts; increased intraocular pressure; exophthalmos; glaucoma.

Immune System: masking of infections; latent infections becoming active; opportunistic infections; hypersensitivity reactions including anaphylaxis; may suppress reactions to skin tests.

Dosage And Administration: The initial dosage may vary from 5 to 60 mg of prednisone per day depending on the specific disease entity being treated. In situations of less severity, lower doses will generally suffice while in selected patients higher initial doses may be required. The initial dosage should be maintained or adjusted until a satisfactory response is noted. If after a reasonable period of time there is a lack of satisfactory clinical response, prednisone should be discontinued and the patient transferred to other appropriate therapy.

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 which will maintain an adequate clinical response is reached. It should be kept in mind that constant monitoring is needed in regard to drug dosage. Included in the 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 prednisone for a period of time consistent with the patient’s condition.

ADT Alternate Day Therapy: Alternate day therapy is a corticosteroid dosing regimen in which twice the usual daily dose of corticosteroid is administered every other morning. The purpose of this mode of therapy is to provide a patient requiring long-term, pharmacologic dose treatment with the beneficial effects of corticoids while minimizing certain undesirable effects, including pituitary-adrenal suppression, the Cushingoid state, corticoid withdrawal symptoms, and growth suppression in children.
