Use of Betamethasone 17-valerateBetamethasone valerate (Betamethasone 17-valerate), the 17-valerate ester of Betamethasone, is a topical corticosteroid with anti-inflammatory activity. Betamethasone valerate is used in the treatment of recurrent aphthous stomatitis. Betamethasone valerate inhibits the binding of the radiolabeled glucocorticoid dexamethasone (3H dexamethasone) to human epidermis and mouse skin with IC50s of 5 and 6 nM, respectively[1][2][3]. |
