Halobetasol propionate is thought to act by the induction of phospholipase A2 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 A2. It is used for the relief of the inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses.
Indication
For the relief of the inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses.
Affected Organisms
Humans and other mammals
Absorption
The extent of percutaneous absorption of topical corticosteroids is determined by many factors including the vehicle and the integrity of the epidermal barrier. Inflammation and/or other disease processes in the skin may increase percutaneous absorption.
