BETAMETHASONE DIPROPIONATE

Betamethasone dipropionate gel (augmented), 0.05%, contains betamethasone dipropionate, USP, a synthetic fluorinated corticosteroid for topical dermatologic use. Betamethasone dipropionate is included in a class of compounds consisting primarily of synthetic corticosteroids for use topically as anti-inflammatory and anti-pruritic agents. Chemically, betamethasone dipropionate is 9-fluoro-11β,17,21-trihydroxy-16β-methylpregna-1,4-diene-3,20-dione 17,21-dipropionate, with the molecular formula C 28 H 37 FO 7 , a molecular weight of 504.6, and the following structural formula: Betamethasone dipropionate is a white to creamy white, odorless crystalline powder, insoluble in water. Each gram of betamethasone dipropionate gel (augmented) contains: 0.64 mg betamethasone dipropionate, USP (equivalent to 0.5 mg betamethasone), in an augmented gel base of carbomer homopolymer type C, propylene glycol, purified water and sodium hydroxide. Chemical Structure

Betamethasone dipropionate gel (augmented) is a super-high potency corticosteroid indicated for the relief of the inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses. Treatment beyond two consecutive weeks is not recommended, and the total dose should not exceed 50 g per week because of potential for the drug to suppress the hypothalamic-pituitary-adrenal (HPA) axis. This product is not recommended for use in pediatric patients under 12 years of age.

Apply a thin layer of betamethasone dipropionate gel (augmented) to the affected skin once or twice daily and rub it in gently and completely. Betamethasone dipropionate gel (augmented) is a super-high potency topical corticosteroid; therefore, treatment should be limited to two weeks, and amounts greater than 50 g per week should not be used. Betamethasone dipropionate gel (augmented) should not be used with occlusive dressings.

Betamethasone dipropionate gel (augmented) is contraindicated in those patients with a history of hypersensitivity to any of the components of the preparation.

In controlled clinical trials, the total incidence of adverse events associated with the use of betamethasone dipropionate gel (augmented) was 10%. These included stinging or burning in 6% of patients, dry skin in 4% of patients, and pruritus in 2% of patients. Less frequently reported adverse reactions were irritation, skin atrophy, telangiectasia, erythema, cracking/tightening of the skin, follicular rash, and allergic contact dermatitis. The following additional local adverse reactions are reported infrequently with topical corticosteroids, but may occur more frequently with super-high potency corticosteroids, such as betamethasone dipropionate gel (augmented). These reactions are listed in approximate decreasing order of occurrence: acneiform eruptions, hypopigmentation, perioral dermatitis, secondary infection, striae, and miliaria.
