Abstract

Acute tolerance to the cardiovascular effects of cocaine has been hypothesized from experiments in which the plasma concentrations of cocaine were rapidly changing. We studied the cardiovascular responses of 8 male human subjects for 4 hours following intravenous bolus doses of cocaine, and compared these to responses in the same subjects after intravenous bolus doses of cocaine followed by continuous intravenous infusions of cocaine designed to maintain steady state plasma levels of cocaine. We found little evidence of tolerance to the tachycardia and hypertensive effects of cocaine during a four hour exposure. Lack of tolerance to the cardiovascular effects of cocaine may be a factor in some types of cocaine related toxicity among cocaine abusers.
