DESCRIPTION
Betamethasone Valerate Cream USP, 0.1% contains betamethasone valerate USP, a synthetic adrenocorticosteroid for dermatologic use. Betamethasone, an analog of prednisolone, has a high degree of glucocorticoid activity and a slight degree of mineralocorticoid activity.
Betamethasone valerate is a white to practically white odorless crystalline powder practically insoluble in water, freely soluble in acetone and chloroform, soluble in alcohol, and slightly soluble in benzene and ether. Chemically it is 9-fluoro-11β,17,21-trihydroxy-16β-methylpregna-1, 4-diene-3,20-dione 17-valerate. The structural formula is:

Each gram of Betamethasone Valerate Cream USP, 0.1% contains 1.2 mg betamethasone valerate (equivalent to 1 mg betamethasone) in a soft, white, hydrophilic cream of ceteareth-15, cetyl alcohol, mineral oil, polyethylene glycol 1000, propylene glycol, purified water, stearyl alcohol, white petrolatum, phosphoric acid and sodium hydroxide (for pH adjustment); chlorocresol is present as a preservative.
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. Inflammation and/or other disease processes in the skin increase percutaneous absorption. Occlusive dressings substantially increase the percutaneous absorption of topical corticosteroids. Thus, occlusive dressings may be a valuable therapeutic adjunct for treatment of resistant dermatoses.
Once absorbed through the skin, topical corticosteroids are handled through pharmacokinetic pathways similar to systemically administered corticosteroids. Corticosteroids are bound to plasma proteins in varying degrees. Corticosteroids are metabolized primarily in the liver and are then excreted by the kidneys. Some of the topical corticosteroids and their metabolites are also excreted into the bile.
