Betamethasone dipropionate was patented by Merck in 1987 as an augmented cream/lotion, Diprolene in the ., and Disprosone in Europe.  These patents expired in 2003 and 2007 respectively leading to generic production of betamethasone dipropionate. During this time other topical corticosteroids such as triamcinolone acetonide and clobetasol propionate also became available as generic creams. Merck filed for "pediatric exclusivity" in 2001 launching a clinical trial to prove betamethasone dipropionate's safety and efficacy for use in pediatrics.
