(Betamethasone Dipropionate)Betamethasone Dipropionate - Betamethasone Dipropionate lotion Prescribing Information
Topical corticosteroids are indicated for the relief of the inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses.
Apply a few drops of Betamethasone Dipropionate Lotion to the affected skin areas and massage lightly until it disappears. Apply twice daily, in the morning and at night.
If an infection develops, appropriate antimicrobial therapy should be instituted.
Betamethasone Dipropionate products should not be used with occlusive dressings.
Topical corticosteroids are contraindicated in those patients with a history of hypersensitivity to any of the components of the preparation.
The following local adverse reactions are reported infrequently when Betamethasone Dipropionate products are used as recommended in the
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.
Betamethasone Dipropionate Lotion, USP 0.05% contains betamethasone dipropionate 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 dipropionate is a white to cream white odorless crystalline powder insoluble in water. Chemically, it is 9-fluoro-11β,17,21-trihydroxy-16β-methylpregna-1,4-diene-3,20-dione 17,21-dipropionate. The structural formula is:

Each gram contains 0.64 mg betamethasone dipropionate (equivalent to 0.5 mg betamethasone) in a vehicle of isopropyl alcohol and purified water slightly thickened with carbomer 974P. Sodium hydroxide solution to adjust pH, if required.
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.
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 (See

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.
