Lithium antagonism of ethanol-induced intoxication: relationship to intracellular lithium levels.

Seventeen detoxified chronic alcoholics participated in a double-blind trial comparing placebo and lithium (Li+) effects on acute ethanol (1 g/kg) intoxication. In a repeated measures, split-half crossover design, subjects were maintained for 7 days on Li+ or placebo before the ethanol challenge. Plasma Li+ levels on day 7 averaged 1.
