Ranitidine 15-25 N-acetyltransferase 1 Rattus norvegicus 52-55 1371435-1 1992 This investigation examined the effect of cimetidine, famotidine, and ranitidine on rat liver acetyl CoA:arylamine N-acetyltransferase (NAT) activity. Ranitidine 70-80 N-acetyltransferase 1 Rattus norvegicus 136-139 1371435-3 1992 At an inhibitor:substrate ratio of 2:1, ranitidine, cimetidine, and famotidine reduced NAT II activity by 9, 48, and 75%, respectively. Ranitidine 40-50 N-acetyltransferase 1 Rattus norvegicus 87-90
