Compared to other blood pressure medications, ACE inhibitors (such as Zestril, Capoten, or Lotensin), alpha-blockers, calcium channel blockers (such as Verapamil and Diltiazem), and ARBs or angiotensin II receptor blockers (such as Losartan) are less likely to cause ED. ARBs have actually been known to improve sexual function and satisfaction in men with high blood pressure.
