Duoval (Valsartan+Hydrochlorothiazide)

Valsartan and hydrochlorothiazide (HCTZ) are often combined in a single medication for the treatment of high blood pressure (hypertension). Valsartan belongs to the class of medications known as angiotensin II receptor blockers (ARBs), which work by blocking the action of angiotensin II, a hormone that constricts blood vessels, leading to relaxation and dilation of blood vessels, thereby reducing blood pressure. Hydrochlorothiazide is a diuretic that works by increasing urine output, reducing the volume of fluid in the body, and lowering blood pressure. When used together, valsartan and HCTZ complement each other's actions, resulting in improved blood pressure control compared to either medication alone. This combination medication is often prescribed to patients who require additional blood pressure reduction beyond what can be achieved with valsartan or HCTZ alone. However, it's essential to use this medication under the guidance of a healthcare professional, as it may cause side effects and require monitoring of electrolyte levels and kidney function.
