The α₁- and β-adrenoceptor antagonist carvedilol reduced MDMA-induced increases in blood pressure, heart rate, and body temperature in healthy subjects, but did not affect the subjective or psychotropic effects of MDMA, such as drug liking, high, or stimulation. Carvedilol also did not alter plasma exposure to MDMA. These findings suggest that α₁- and β-adrenoceptors contribute to the cardiostimulant and thermogenic effects of MDMA in humans but not to its psychological effects, indicating carvedilol could be useful for treating cardiovascular and hyperthermic complications associated with ecstasy use.
