Summary
This study was designed to test whether a new fixed-dose combination of two blood pressure medicines (olmesartan and chlorthalidone) works as well as an existing combination (olmesartan and hydrochlorothiazide) in people with untreated high blood pressure. The trial was withdrawn before any participants were enrolled, so no data were collected.
