In a double‐blind, placebo‐controlled study involving five male alcoholic volunteers, oral administration of 0.7 mglkg of calcium carbimide (CC) 12 hr before ingestion of ethanol (0.125, 0.25, and 0.5 gm/kg) produced an interaction consisting of increased blood acetaldehyde level, tachycardia, and decreased diastolic blood pressure. The order of intensity of the interaction with regard to ethanol dose was 0.5 > 0.25 > 0.125 gm/kg. The subjects were aware of a CC‐ethanol interaction only for 0.25 and 0.5 gm/kg of ethanol, for which heart rate was elevated above 100 bpm. With the criterion of heart rate above 100 as indicative of the CC‐ethanol interaction, the onset was 0.25 and 0.38 hr for the 0.5 and 0.25 gm/kg ethanol doses and the duration of the interaction was 1.0 and 0.38 hr, respectively. There were positive, linear correlations between blood acetaldehyde level and both heart rate and pulse pressure. There was appreciable individual variability in the intensity and duration of the interaction. Pretreatment with CC reduced the rate of ethanol metabolism at the 0.5 gm/kg ethanol dose.
