CO-DIOVAN 160MG/12.5MG is a prescription medication designed to manage high blood pressure (hypertension) in adults. This formulation combines Valsartan, an angiotensin II receptor blocker, with Hydrochlorothiazide, a diuretic. The combination works synergistically to lower blood pressure by relaxing blood vessels and reducing fluid retention. It is often prescribed for patients who require a stronger dose to achieve optimal blood pressure control.
