Abstract

The aim of this study was to compare the effect of antihypertensive treatment with valsartan or cavedilol on sexual activity in hypertensive men who were never treated for hypertension. A total of 160 newly diagnosed hypertensive men (diastolic blood pressure [DBP] > or = 95 mm Hg and < 110 mm Hg), aged 40 to 49 years, all married and without any previous sexual disfunction, were enrolled. After a 4-week placebo period, the patients were divided into two groups: a) 120 patients were randomized to receive carvedilol 50 mg once daily or valsartan 80 mg once daily for 16 weeks according to a double-blind, cross-over design; after another 4-week placebo period, patients were crossed over to the alternative regimen for a further 16 weeks; b) 40 patients were treated with placebo according to a single-blind design for 16 weeks. At the screening visit and every 4 weeks thereafter, blood pressure (BP) was evaluated and patients were interviewed by a questionnaire about their sexual activity. Blood pressure was significantly lowered by both treatments, with a 48% of normalization with valsartan and 45% with carvedilol. During the first month of therapy, sexual activity (assessed as number of sexual intercourse episodes per month) declined with both drugs as compared with baseline, although the decrease was statistically significant in the carvedilol (from 8.2 to 4.4 sexual intercourse episodes, P < .01) but not in the valsartan-treated patients (from 8.3 to 6.6 sexual intercourse episodes, not significant). Ongoing with the treatment the sexual activity further worsened with carvedilol (3.7 sexual intercourse episodes per month) while fully recovered and also improved with valsartan (10.2 sexual intercourse episodes per month). The results were confirmed by the cross-over. Erectile dysfunction was a complaint of 15 patients with carvedilol (13.5%), one patient with valsartan (0.9%), and one patient in the placebo group. These findings suggest that carvedilol induces a chronic worsening of sexual activity, whereas valsartan not only does not significantly worsen sexual activity but may even improve it.
