The effects of delapril in combination with indapamide on glomerular filtration rate in elderly hypertensive patients.

We performed a placebo-controlled trial on the effects of a combined antihypertensive treatment with delapril, a new nonsulfhydryl angiotensin-converting enzyme inhibitor, and indapamide, a sulfonamide diuretic. We studied 28 elderly patients aged 65-85 years (mean age, 69 +/- 1 years) who took 30 mg delapril in combination with 1.25 mg indapamide once daily for 24 weeks. In the present study (performed simultaneously with our trial on the effects of delapril/indapamide on left ventricular mass in elderly patients with hypertension and on the same patients), we report the effects of this drug combination on glomerular filtration rate. Sitting arterial pressure (mean +/- SE) decreased from 156 +/- 1. 5/101 +/- 1 mm Hg at baseline to 133 +/- 1/73 +/- 1 mm Hg at the end of the 24-week treatment period (p < 0.0001). No significant changes in heart rate or episodes of orthostatic hypotension were observed. Glomerular filtration rate increased from 91.8 +/- 4.42 mL/min at baseline to 106.3 +/- 4.5 mL/min (p < 0.001) at the end of treatment. Our results show that the combination of delapril and indapamide is effective in the elderly hypertensive patient, with a favorable effect on the prevention of deterioration of kidney function.
