Comparison of Single and Combination Diuretics in Low-Renin Hypertension

Summary

The purpose of this study is to determine whether the routine combination of optimal thiazide and K+-sparing diuretic will both increase efficacy of BP reduction and reduce risk of glucose intolerance; and whether K+-sparing diuretics alone may have a neutral or even beneficial effect upon glucose tolerance.
