Diovan 80mg is a prescription medication containing valsartan, an angiotensin II receptor blocker used to treat high blood pressure and heart failure. Each pack contains 28 film-coated tablets manufactured by Novartis Pharmaceuticals. The tablets help relax blood vessels to lower blood pressure. The active ingredient valsartan works by blocking the action of angiotensin II, a natural substance that causes blood vessels to tighten, thereby helping to lower blood pressure. The medication comes in a light blue and white box with clear Novartis branding. The tablets should be taken once daily with or without food, as prescribed by your healthcare provider. This is a prescription-only medication that requires proper medical supervision.
