Overview
DESCRIPTION The topical corticosteroids constitute a class of primarily synthetic steroids used as anti- inflammatory and antipruritic agents. The steroids in this class include halcinonide. Halcinonide is designated chemically as 21-Chloro-9-fluoro-11β, 16α, 17-trihydroxypregn-4-ene-3, 20-dione cyclic 16, 17-acetal with acetone. Structural formula: C 24 H 32 ClFO 5 , MW 454.
Mechanism of Action
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 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.
