Pharmacological group and ATC code

Corticosteroid for topical use; D07AD01.

Pharmacology

Following topical application, Clobetasol produce anti-inflammatory, antipruritic, anti-exudate, antiallergic and vasoconstrictor actions. The activity of the drug is thought to result at least in part from binding with a steroid receptor. Clobetasol decrease inflammation by stabilizing leukocyte lysosomal membranes, preventing release of destructive acid hydrolases from leukocytes; inhibiting macrophage accumulation in inflamed areas; reducing leukocyte adhesion to capillary endothelium; reducing capillary wall permeability and edema formation; decreasing complement components; antagonizing histamine activity and release of kinin from substrates; reducing fibroblast proliferation, collagen deposition, and subsequent scar tissue formation; and possibly by other mechanisms as yet unknown.

Pharmacokinetics

Absorption

Following topical application of Clobetasol propionate to most areas of normal skin, only small amounts of the drug appear to reach the dermis and subsequently the systemic circulation with the usual dosage; however, systemic absorption may be increased when the usual dosage is exceeded or when the skin is inflamed or diseased.

Elimination

Following percutaneous penetration of Clobetasol propionate, drug that is systemically absorbed probably follows the metabolic pathways of systemically administered corticosteroids. However, systemic metabolism of Clobetasol has not been fully characterized or quantified. Clobetasol and its metabolites are excreted in bileand in urine in animals.

Uses and administration
Dermatosis including psoriasis, eczema in case of applied topical therapy with corticosteroids is effective.

Adminsitration

Topical Clobetasol is applied sparingly in thin films and are rubbed gently into the affected area twice daily, preferably in the morning and evening, some patients may respond initially to once-daily.

If clinical improvement does not occur after 2 weeks of treatment, the diagnosis should be reevaluated.

Treatment of patients with facial lesions by Clobetasol applications should not exceed 5 days.

Adverse effects

Local Effects

Burning, itching, irritation, folliculitis, hypertrichosis, acne, hypopigmentation, perioral dermatitis, allergic contact dermatitis, maceration of the skin, the accession of secondary infections, skin atrophy, striae, miliaria, cracked skin.

Local adverse Clobetasol effects occur most frequently with occlusive dressings, especially with prolonged therapy, and may require discontinuing the occlusive dressing.

Prolonged use at high doses may cause symptoms of Cushing, especially in children.

Adverse dermatologic effects of Clobetasol usually improve when the drug is discontinued but may persist for long periods; atrophic striae may be permanent.

Long-term use of Clobetasol and its application under occlusive dressings may suppress the hypothalamic-pituitary-adrenal (HPA) axis. Itmay occur when using 2 g of drug (1 mg of clobetasol propionate per day).

Contraindications
  • Hypersensitivity to clobetasol or any other ingredients.
  • Clobetasol should not be used with occlusive dressings.
  • Clobetasol contraindicated for children to 17 years of age
  • Tuberculosis cutis
  • Fungal infections of the skin
  • Precautions
    Clobetasol is not intended for ophthalmic use. Avoid contact with eyes, mouth, and nose.

    If irritation or sensitization occurs following topical application of Clobetasol , the drug should be discontinued.

    General

    Systemic absorption of topical corticosteroids can produce reversible hypothalamic-pituitary-adrenal (HPA) axis suppression with the potential for glucocorticosteroid insufficiency after withdrawal of treatment. Conditions which augment systemic absorption include use over large surface areas, prolonged use, and use under occlusive dressings.

    It should avoid applying the product on injured skin or open wounds

    If irritation develops, Clobetasol should be discontinued and appropriate therapy instituted.

    Pediatric Use
    Safety and efficacy of Clobetasol have not been established in pediatric patients. Therefore, use of Clobetasol in children younger than 17 years of age is not recommended.

    Pregnancy
    Clobetasol should be used during pregnancy only when the potential benefits justify the possible risks to the fetus. The drug should not be used on extensive areas, in large amounts, or for prolonged periods in pregnant women.

    Lactation
    Clobetasol should not be used during breast-feeding.

    Drug interactions

    None well documented.

    Overdosage

    Symptoms: excessive or prolonged use of topical corticosteroids can suppress pituitary-adrenal function, resulting in secondary adrenal insufficiency and produce manifestations of hypercorticism.

    Treatment: appropriate symptomatic treatment is indicated. Acute hypercorticoid symptoms are usually reversible. Treat electrolyte imbalance, if necessary. In case of chronic toxicity, slow withdrawal of corticosteroids is advised. Adminster oral sodium bicarbonate to alkalinize the urine and force diuresis.
