Hypothermia has previously been shown to be a component of the disulfiram-ethanol reaction (DER). In rats, hypothermia correlated with the hypotension and tachycardia observed when ethanol was administered 8 hours after disfulfiram treatment. These studies have now been extended, and in addition, the role of diethyldithiocarbamate (DDTC) and diethyldithiocarbamate-methyl ester (DDTC-MF) in the DER have been examined. In rats challenged with ethanol (1g/kg, i.p.) 4 and 24 hours after disulfiram (75 mg/kg, i.p.) no hypothermia was observed, but was found when ethanol was given 8, 12 and 16 hours after disulfiram. Hypotension and tachycardia were found at all time periods studied. Low Km ALDH also was inhibited at the 4, 8, 16 and 24 hour time periods. Although pretreatment with DDTC and DDTC-ME failed to produce hypothermia, hypotension and tachycardia were observed in rats challenged with ethanol. As with disulfiram administration, hypothermia did not correlate with ALDH inhibition in the DDTC and DDTC-ME studies. These studies support the known myriad of effects produced during the DER, and provide additional evidence that difference mechanisms contribute to the complexity of the disulfiram-ethanol reaction.
