A comparative study of the interactions of alcohol with amitriptyline, fluoxetine and placebo in normal subjects

Abstract

1. Twelve normal volunteer subjects were given amitriptyline, fluoxetine and placebo in clinically relevant doses, each for a period of 7 days. A minimum of 28 days intervened between each drug treatment. 2. A battery of physiological, psychomotor and subjective tests was administered before drugs and on days 4 and 8. 3. On day 8 a measured dose of alcohol was given and the tests repeated 1 hour and 3 hours later. 4. Before alcohol, little effect was shown on physiological or psychomotor activity. Subjective ratings indicated that amitriptyline was less-well tolerated than fluoxetine. 5. Significant differences were found for many measures after alcohol but there were few differences with respect to the drugs.
