Can Cozaar generic be substituted for DiovanHCT320mg/25mg? I need a cheaper drug than Diovan?

Cozaar (losartan potassium) is a prescription medicine that has been licensed to treat several conditions related to the heart and blood vessels. It is part of a class of drugs called angiotensin II receptor blockers, or ARBs for short.

Uses of Cozaar include: High blood pressure (hypertension) control &
Diabetic nephropathy treatment.

The medication is not a cure for high blood pressure or diabetic nephropathy. It has also been approved for use in children ages six and older to treat high blood pressure.

Diovan HCT (valsartan and hydrochlorothiazide) is a prescription medicine that has been licensed to treat high blood pressure (hypertension) in adults. The medication has not been approved for use in children.

Diovan HCT is a combination of two medicines -- Diovan and
hydrochlorothiazide. Diovan is a newer type of blood pressure medicine known as an angiotensin II receptor blocker, or ARB for short. As the name implies, Diovan blocks angiotensin II receptors. This decreases the effectiveness of a chemical known as angiotensin II, which normally causes blood vessels to narrow (constrict). By blocking the effects of angiotensin II, Diovan causes blood vessels to relax.

Hydrochlorothiazide is a diuretic, which is commonly referred to as a "water pill." It works by increasing the amount of salt and water the kidneys remove from the blood. This extra salt and water is passed out through the urine. By increasing the amount of water removed from the blood, hydrochlorothiazide causes a decrease in blood volume.

Because of its combined effects, Diovan HCT causes a greater drop in blood pressure than when either medicine is used alone.

Both meds are different, please do talk a doc before you substitute the med. you could perhaps try taking to a pharmacist for a cheaper substitute.

Please take care.
