Antihypertensive & Erectile Dysfunction

  • Experimental and clinical have strongly indicated that older antihypertensive drugs exert detrimental effects on erectile function while newer agents exert either neutral or even beneficial effects.
  • Accumulating data indicate that antihypertensive drug therapy is associated with erectile dysfunction, that antihypertensive drugs have divergent effects on erectile function which is either
           a)   Detrimental (diuretics, beta-blockers, centrally acting agents)
               b)   Neutral (calcium antagonists, ACE inhibitors)
               c)   Potentially beneficial (angiotensin receptor blockers, nebivolol)
  • Older antihypertensive drugs (diuretics and beta-blockers) are not ideal candidates for these patients due to their detrimental effects on erectile function, and should be used only if they are absolutely indicated.
  •  In case more than one class is indicated for an individual patient, the choice of an ARB should be considered.
  • Switching from a drug with negative to a drug with positive effects on erectile function seems to be beneficial in hypertensive patients with erectile dysfunction.

Choice of ARB in Erectile Dysfunction




Losartan
  • Based on study, treatment with losartan improved erectile function, sexual satisfaction and frequency of sexual activity in hypertensive patients.
  • Losartan alone or in combination with tadalafil significantly improved ED in diabetic patients, those with mild to moderate ED profiting the most from its use


Irbesartan
  • In mice, irbesartan was shown to improve penile endothelial function by reduction of vascular and cavernosal oxidative stress





Valsartan
  • In large prospective studies, the use of valsartan increased the rate of sexual intercourses per week and caused a reduction in ED, with improved orgasmic function, intercourse and overall sexual satisfaction in hypertensive men.
  • In comparative studies, long-term use of valsartan was also shown to significantly improve sexual activity in comparison with the β-blockers carvedilol and atenolol, with the latter also reducing serum testosterone levels
