Valsartan is an angiotensin II receptor blocker (ARB) used to manage high blood pressure and heart failure. It helps to relax blood vessels and improve blood flow.
Mechanism of Action
Valsartan works by blocking the action of angiotensin II, a hormone that causes blood vessels to constrict. By inhibiting this action, valsartan helps to relax and widen blood vessels, which lowers blood pressure and reduces strain on the heart.
Uses
- High Blood Pressure: Valsartan is used to treat hypertension and reduce the risk of stroke and heart attack.
- Heart Failure: It helps manage heart failure by reducing fluid buildup and improving heart function.
- Post-Heart Attack: Valsartan can be used to improve survival rates after a heart attack.
Side Effects
Common side effects of valsartan include:
- Dizziness: Patients may experience dizziness or lightheadedness.
- Hyperkalemia: Elevated potassium levels can occur.
- Kidney Problems: Valsartan can affect kidney function, leading to kidney impairment.
Precautions
To use valsartan safely, consider these precautions:
- Monitor Blood Pressure and Kidney Function: Regular monitoring is necessary to ensure efficacy and detect any adverse effects.
- Avoid Potassium Supplements: High potassium levels can be exacerbated by valsartan, so avoid potassium supplements unless prescribed.
- Be Aware of Drug Interactions: Inform healthcare providers about all current medications to avoid potential interactions.
