Spironolactone and altizide used in combination with enalapril: Twenty-four-hour ambulatory recording of blood pressure

The addition of enalapril or acebutolol to a regimen of altizide + spironolactone in patients with moderate hypotension was investigated in a multicenter study of S3 patients. The patients underwent semiambulatory 24-hour blood pressure monitoring, especially to observe hypotensive episodes. In the 25 patients uncontrolled with altizide + spironolactone alone, enalapril and acebutolol were about equally effective in reducing blood pressure. The incidence of hypotension was low and comparable for both treatment groups, provided that the initial dose of angiotensin-converting enzyme inhibitor was low (5 mg).
