A Study of Valsartan Administered Once Daily Versus Twice Daily, in Patients With Stable, Chronic Heart Failure

A 12-Week Multicenter, 2-Arm Regimen, Exploratory Study to Evaluate the Tolerability and Safety of Valsartan Administered Once Daily vs Daily, in Patients With Stable, Chronic Heart Failure (NYHA Class Ll-lll)

This study will evaluate the tolerability and safety of valsartan in patients with stable, chronic heart failure (NYHA Class ll-lll). The 12-week double blind study has a 2-week (maximum) screening, and a 10-week active treatment phase. In each of the treatment arms (QD and BID), patients are up-titrated to a maximum valsartan total daily dose of 320 mg. Patients remain on their prior CHF standard care therapy throughout the study period, and the up-titration of valsartan is based on patient tolerability.
