Diovan HCT 320/25 contains two active ingredients: valsartan (320 mg) and hydrochlorothiazide (25 mg).
Valsartan’s Role
Valsartan is an angiotensin II receptor blocker (ARB). It works by blocking the action of angiotensin II, a hormone that narrows blood vessels. This blockage causes blood vessels to relax and widen, lowering blood pressure.
Hydrochlorothiazide’s Role
Hydrochlorothiazide is a thiazide diuretic. It increases the excretion of sodium and water from the body through urine. This reduces blood volume, further contributing to lower blood pressure.
Combined Action
The combination of valsartan and hydrochlorothiazide provides a synergistic effect. Valsartan’s action on blood vessels complements hydrochlorothiazide’s effect on blood volume, leading to more effective blood pressure control than either drug alone. This makes it particularly useful for individuals whose blood pressure isn’t adequately controlled with a single medication.
Important Considerations
- This medication is prescribed for hypertension (high blood pressure). Always follow your doctor’s instructions regarding dosage and administration. Report any side effects, such as dizziness, lightheadedness, or changes in urination, to your doctor immediately. Inform your doctor about other medications you are taking, including over-the-counter drugs and supplements, to avoid potential interactions. Regular blood pressure monitoring is crucial while taking this medication.
