Abstract
Alcohol (ethanol) is absorbed slowly from the stomach and rapidly from the small intestine, and the rate of its absorption depends on the rate of gastric emptying. When gastric emptying is fast, the absorption of alcohol is fast. When gastric emptying is slow the absorption of alcohol is delayed and peak blood alcohol concentrations are reduced. Alterations of the gastric emptying rate, which may have a physiologic, pharmacologic or pathologic cause, markedly influence the rate of alcohol absorption. The gastric emptying rate makes an important contribution to inter- and intraindividual variations in the rate of alcohol absorption and therefore the timing and magnitude of the acute intoxicating effect of an oral dose of alcohol.
摘要
酒精（乙醇）在胃中吸收缓慢，在小肠中吸收迅速，其吸收速率取决于胃排空速率。当胃排空快时，酒精吸收快。当胃排空慢时，酒精吸收延迟，血中酒精浓度峰值降低。胃排空速率的改变可能有生理、药理或病理原因，会显著影响酒精吸收速率。胃排空速率对个体间和个体内酒精吸收速率的差异有重要影响，因此也影响口服一定剂量酒精产生急性中毒效应的时间和程度。
