title: The effect of proadifen on the metabolism of adinazolam.
abstract: Binding affinities of adinazolam and its metabolite mono-N-demethyladinazolam, U-42352, to the brain tissue are not altered by the presence of proadifen (SKF-525A) in [3H]flunitrazepam [( 3H]FNZ) binding assays in-vitro. Pretreatment of mice with proadifen significantly blocked the ability of intravenously administered adinazolam to inhibit [3H]FNZ binding in the studies ex-vivo. The binding profile of [3H]FNZ to the brain tissue was not significantly different when animals were treated with U-42352 or proadifen with U-42352. These results suggest that proadifen may block the conversion of adinazolam to its active metabolite U-42352.
