The effect of labetalol and propranolol on the pressor response to sexual arousal in women.

Abstract

1 The effect of a single oral dose of labetalol (100 mg), propranolol (80 mg) and placebo on the pressor response to sexual autostimulation has been studied in six female volunteers. 2 Labetalol but not propranolol significantly reduced the increase in blood pressure that occurred at orgasm. 3 The subjective features of the sexual response were assessed by each subject using visual analogue scales. 4 Subjects reported a significant reduction in vaginal lubrication with labetalol compared to both placebo and propranolol. 5 No other effects were noted.
