Avapro is FDA-approved for treating essential hypertension (high blood pressure) in adults and pediatric patients (ages 6-16). It is also indicated to slow the progression of diabetic nephropathy in patients with type 2 diabetes, hypertension, and renal disease.
Avapro contains irbesartan, which blocks the action of angiotensin II—a hormone that causes blood vessels to constrict. By inhibiting this hormone, Avapro allows blood vessels to relax and widen, which reduces blood pressure and improves blood flow.
Avapro should not be used during pregnancy as it may cause harm to the fetus. Common side effects may include dizziness, fatigue, and orthostatic hypotension. Patients should avoid potassium supplements or salt substitutes containing potassium unless directed by their healthcare provider. This medication may interact with other blood pressure medications, lithium, or NSAIDs.
