title: Effects of carbamazepine on acute responses to smoked cocaine-base in human cocaine users.
abstract: A double-blind, placebo-controlled cross-over study was conducted to determine the effects of carbamazepine on the acute physiological and subjective responses to a single dose of smoked cocaine-base. Male cocaine users (N = 6) were given 400 mg carbamazepine or placebo, each for a period of 5 days. At the end of the 5-day period, a 40 mg dose of smoked cocaine was administered. The results showed a significantly higher heart rate, diastolic blood pressure elevation, and blood pressure-heart rate product under the carbamazepine compared to the placebo condition. There were no effects of carbamazepine on the subjective responses from cocaine. The increase in cardiovascular functions indicates a need to be cautious in the use of carbamazepine in the treatment of cocaine abusers.
