Abstract

The comparative effect of famotidine or cimetidine on theophylline disposition was determined in healthy volunteers. Cimetidine, but not famotidine, caused a reduction in the rate of elimination of theophylline. The mean total body clearance of theophylline was reduced from 57.6 ml min-1 before cimetidine to 39.5 ml min-1 during cimetidine; and the half-life was prolonged from 8.7 h before cimetidine to 12 h during cimetidine. The volume of distribution and renal excretion of theophylline were not affected by either famotidine or cimetidine.

摘要

在健康志愿者中测定了法莫替丁或西咪替丁对茶碱处置的比较效果。西咪替丁而非法莫替丁导致茶碱消除速率降低。茶碱的平均全身清除率在服用西咪替丁前为57.6 ml/min,服用西咪替丁期间降至39.5 ml/min;半衰期从服用西咪替丁前的8.7小时延长至服用西咪替丁期间的12小时。法莫替丁和西咪替丁均未影响茶碱的分布容积和肾排泄。
