生物活性:
BMY-25271 is a histamine H2 receptor antagonist.

体内研究:
BMY-25271 is a histamine H2 receptor antagonist. The dose response curves are parallel and oral ED50 values derived from probit analysis are 0.093, 0.97 and 6.9 mg/kg for BMY-25271, ranitidine and cimetidine, respectively. BMY-25271, therefore, is about 10 and 74 times more potent than ranitidine and cimetidine, respectively. Pretreatment with the highest dose of BMY-25271 does not significantly affect the absorption of aspirin or the formation of its major metabolite, salicylic acid.
