Corticosteroid with anti-inflammatory, antipruritic, and vasoconstrictive properties.
Betamethasone dipropionate is a corticosteroid that diffuses across cell membranes and binds to glucocorticoid receptors, forming a complex that translocates to the nucleus and modulates gene transcription. It induces phospholipase A2 inhibitory proteins (lipocortins), thereby inhibiting the release of arachidonic acid and decreasing the synthesis of prostaglandins and leukotrienes. This results in anti-inflammatory, antipruritic, and vasoconstrictive effects.
Topical application of a thin film twice daily to affected areas. Not for ophthalmic, oral, or intravaginal use.
Apply a thin layer to affected area once or twice daily. Maximum 50 g per week.

Terminal elimination half-life is approximately 1.5–2 hours. This short half-life supports twice-daily dosing for maintenance of therapeutic levels.
Terminal elimination half-life: 3-4 hours; prolonged in hepatic impairment
Primarily renal (hepatic metabolism to inactive metabolites; <1% excreted unchanged in urine). Fecal elimination accounts for <5%.
Renal (60-70% as unchanged drug and metabolites), biliary/fecal (30-40%)
