Aldactazine/captopril combination, safe and effective in mild to moderate systemic hypertension: report on a...

The safety and efficacy of a thiazide/potassium-sparing diuretic and an angiotensin-converting enzyme inhibitor used concomitantly was evaluated in a large, multicenter study. Aldactazine was administered alone for 2 months, after which time captopril was added in those whose blood pressure had not normalized (332 patients). At the end of the 6-month study, control of blood pressure was achieved in 88% of the patients with one or the other regimen. No clinically significant changes were recorded for a number of biologic parameters. Specifically, there was 1 case of hyperkalemia (6 mmol/liter), a very low incidence of hypotension (1.6%), and a low rate of adverse effects. Therefore, such a combination could provide important therapeutic benefits in hypertensive patients.
