Clinical Pharmacology Section

CLINICAL PHARMACOLOGY: Topical corticosteroids share anti-inflammatory, antipruritic and vasoconstrictive actions. The mechanism of anti-inflammatory activity of the topical corticosteroids is unclear. Various laboratory methods, including vasoconstrictor assays, are used to compare and predict potencies and/or clinical efficacies of the topical corticosteroids. There is some evidence to suggest that a recognizable correlation exists between vasoconstrictor potency and therapeutic efficacy in man.

PHARMACOKINETICS SECTION

Pharmacokinetics: The extent of percutaneous absorption of topical corticosteroids is determined by many factors including the vehicle, the integrity of the epidermal barrier, and the use of occlusive dressings. Topical corticosteroids can be absorbed from normal intact skin. Inflammation and/or disease processes in the skin increase the percutaneous absorption of topical corticosteroids. Occlusive dressings substantially increase the percutaneous absorption of topical corticosteroids. Thus, occlusive dressings may be a valuable therapeutic adjunct for treatment of resistant dermatoses. (See DOSAGE AND ADMINISTRATION .)

Once absorbed through the skin, topical corticosteroids are handled through pharmacokinetic pathways similar to systemically administered corticosteroids. Corticosteroids are bound to plasma proteins in varying degrees. Corticosteroids are metabolized primarily in the liver and are then excreted by the kidneys. Some of the topical corticosteroids and their metabolites are also excreted into the bile.

Indications & Usage Section

INDICATIONS AND USAGE: NuCort lotion is a topical corticosteroid and is indicated for the relief of the inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses.

Contraindications Section

CONTRAINDICATIONS: Topical corticosteroid products are contraindicated in those patients with a history of hypersensitivity to any of the components of the preparation.

Precautions:

GENERAL PRECAUTIONS SECTION

General: Systemic absorption of topical corticosteroids has produced reversible hypothalamicpituitary-adrenal (HPA) axis suppression, manifestations of Cushing’s syndrome, hyperglycemia and glucosuria in some patients. Conditions which augment systemic absorption include the application of the more potent steroids, use over large surface areas, prolonged use and the addition of occlusive dressings. Therefore, patients receiving a large dose of a potent topical steroid applied to a large surface area or under an occlusive dressing should be evaluated periodically for evidence of HPA axis suppression by using the urinary free cortisol and ACTH stimulation tests. If HPA axis suppression is noted, an attempt should be made to withdraw the drug, to reduce the frequency of application, or to substitute a less potent steroid. Recovery of HPA axis function is generally prompt and complete upon discontinuation of the drug. Infrequently, signs and symptoms of steroid withdrawal may occur, requiring supplemental systemic corticosteroids. In pediatric patients absorption may result in higher blood levels and thus more susceptibility to systemic toxicity. (See PRECAUTIONS-Pediatric Use .) If irritation develops, topical corticosteroids should be discontinued and appropriate therapy instituted.

In the presence of dermatological infections, the use of an appropriate antifungal or antibacterial agent should be instituted. If a favorable response does not occur promptly, the corticosteroid should be discontinued until the infection has been adequately controlled.

INFORMATION FOR PATIENTS SECTION

Information for the Patient: Patients using topical corticosteroids should receive the following information and instructions:

• This medication is to be used as directed by the physician. It is for external use only. Avoid contact with the eyes.
• Do not use this medication for any disorder other than for which it has been prescribed.
• The treated skin area should not be bandaged or otherwise covered or wrapped as to be occlusive unless directed by the physician.
• Report any signs of local adverse reactions especially under occlusive dressings.
• Do not use any tight fitting diapers or plastic pants on a pediatric patient being treated in the diaper area, as these garments may constitute occlusive dressings.

LABORATORY TESTS SECTION

Laboratory Tests: The following tests may be helpful in evaluating the HPA axis suppression:

•  Urinary free cortisol test
•  ACTH stimulation test

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION

Carcinogenesis, Mutagenesis, and Impairment of Fertility: Long-term animal studies have not been performed to evaluate carcinogenic potential or the effect on fertility of topical corticosteroids.

PREGNANCY SECTION

Pregnancy Category C: Corticosteroids are generally teratogenic in laboratory animals when administered systemically at relatively low dosage levels. The more potent corticosteroids have been shown to be teratogenic after dermal application in laboratory animals. There are no adequate and well-controlled studies in pregnant women of teratogenic effects from topically applied corticosteroids. Therefore, topical corticosteroids should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Drugs of this class should not be used extensively on pregnant patients, in large amounts, or for prolonged periods of time.

NURSING MOTHERS SECTION

Nursing mothers: It is not known whether topical administration of corticosteroids could result in sufficient systemic absorption to produce detectable quantities in breast milk. Systemically administered corticosteroids are secreted into breast milk in quantities not likely to have a deleterious effect on the infant. Caution should be exercised when any topical corticosteroids are administered to a nursing woman.

PEDIATRIC USE SECTION

Pediatric Use: Pediatric patients may demonstrate greater susceptibility to topical corticosteroid-Induced HPA axis suppression and Cushing’s Syndrome than mature patients because of a larger skin surface area to body weight ratio. Hypothalamic-pituitary-adrenal (HPA) axis suppression, Cushing’s syndrome and intracranial hypertension have been reported in pediatric patients receiving topical corticosteroids. Manifestations of adrenal suppression in pediatric patients include linear growth retardation, delayed weight gain, low plasma cortisone levels and absence of response to ACTH stimulation. Manifestations of intracranial hypertension include bulging fontanelles, headaches, and bilateral papilledema. Administration of topical corticosteroids to pediatric patients should be limited to the least amount compatible with an effective therapeutic regimen. Chronic corticosteroid therapy may interfere with the growth and development of pediatric patients.
