Abstract

Renal function declines progressively in patients who have diabetic nephropathy, and the decline may be slowed by antihypertensive drugs. The purpose of this study was to determine whether captopril has kidney-protecting properties independent of its effect on blood pressure in diabetic nephropathy. We performed a randomized, controlled trial comparing captopril with placebo in patients with insulin-dependent diabetes mellitus in whom urinary protein excretion was > or = 500 mg per day and the serum creatinine concentration was < or = 2.5 mg per deciliter (221 mumol per liter). Blood-pressure goals were defined to achieve control during a median follow-up of three years. The primary end point was a doubling of the base-line serum creatinine concentration. Two hundred seven patients received captopril, and 202 placebo. Serum creatinine concentrations doubled in 25 patients in the captopril group, as compared with 43 patients in the placebo group (P = 0.007). The associated reductions in risk of a doubling of the serum creatinine concentration were 48 percent in the captopril group as a whole, 76 percent in the subgroup with a baseline serum creatinine concentration of 2.0 mg per deciliter (177 mumol per liter), 55 percent in the...Continue Reading

Antihypertensive Agents: Mechanisms of Action

Antihypertensive drugs are used to treat hypertension (high blood pressure) which aims to prevent the complications of high blood pressure, such as stroke and myocardial infarction. Discover the latest research on antihypertensive drugs and their mechanism of action here.
