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. General- Systemic absorption of topical corticosteroids has produced reversible hypothalamic-pituitary-adrenal (HPA) axis suppression, manifestations of Cushing’s syndrome, hyperglycemia and glucosuria in some patients. Topical corticosteroids are contraindicated in those patients with a history of hypersensitivity to any of the components of the preparation. Topical corticosteroids are indicated for the relief of the inflammatory and pruritic manifestations of corticosteroid-responsive dermatosis.

Corticosteroids are metabolized primarily in the liver and are then excreted by the kidneys. Corticosteroids are bound to plasma proteins in varying degrees. Once absorbed through the skin, topical corticosteroids are handled through pharmacokinetic pathways similar to systemically administered corticosteroids. Thus, occlusive dressings may be a valuable therapeutic adjunct for treatment of resistant dermatoses (see DOSAGE AND ADMINISTRATION). Occlusive dressings substantially increase the percutaneous absorption of topical corticosteroids. Inflammation and/or other disease processes in the skin increase percutaneous absorption. Topical corticosteroids can be absorbed from normal intact skin. 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. There is some evidence to suggest that a recognizable correlation exists between vasoconstrictor potency and therapeutic efficacy in man. Various laboratory methods, including vasoconstrictor assays, are used to compare and to predict potencies and/or clinical efficacies of the topical corticosteroids. The mechanism of anti-inflammatory activity of the topical corticosteroids is unclear. Topical corticosteroids share anti-inflammatory, antipruritic and vasoconstrictive actions. The topical corticosteroids, including hydrocortisone, constitute a class of primarily synthetic steroids used as anti-inflammatory and antpruritic agents. Its molecular weight is 362.47 and its CAS Registry Number is 50-23-7.
