Abbreviated New Drug Application
HALOBETASOL PROPIONATE - HALOBETASOL PROPIONATE OINTMENT PHYSICIANS TOTAL CARE, INC. ---------- For Dermatologic Use Only. Not for Ophthalmic Use. Rx Only DESCRIPTION Halobetasol propionate ointment, 0.05% contains halobetasol propionate, a synthetic corticosteroid for topical dermatological use. The corticosteroids constitute a class of primarily synthetic steroids used topically as an anti-inflammatory and antipruritic agent. Chemically halobetasol propionate is 21-chloro-6α, 9-difluoro-11β, 17-dihydroxy-16β-methylpregna- 1, 4-diene-3-20-dione, 17-propionate, C H ClF O . It has the following structural formula: Halobetasol propionate has the molecular weight of 485. It is a white crystalline powder insoluble in water. Each gram of halobetasol propionate ointment, 0.05% contains 0.5 mg of halobetasol propionate in a base of aluminum stearate, beeswax, pentaerythritol cocoate, stearyl citrate, petrolatum, propylene glycol and sorbitan sesquioleate. CLINICAL PHARMACOLOGY Like other topical corticosteroids, halobetasol propionate has anti-inflammatory, antipruritic and vasoconstrictive actions. The mechanism of the anti-inflammatory activity of the topical corticosteroids, in general, is unclear. However, corticosteroids are thought to act by the induction of phospholipase A , inhibitory proteins, collectively called lipocortins. It is postulated that these proteins control the biosynthesis of potent mediators of inflammation such as prostaglandins and leukotrienes by inhibiting the release of their common precursor arachidonic acid. Arachidonic acid is released from membrane phospholipids by phospholipase A . PHARMACOKINETICS The extent of percutaneous absorption of topical corticosteroids is determined by many factors including the vehicle and the integrity of the epidermal barrier. Occlusive dressings with hydrocortisone for up to 24 hours have not been demonstrated to increase penetration; however, occlusion of hydrocortisone for 96 hours markedly enhances penetration.
