Hexartan 80 Tablet contains Telmisartan 80 mg, an angiotensin II receptor antagonist primarily indicated for the treatment of hypertension. By selectively blocking the binding of angiotensin II to the AT1 receptor, Telmisartan inhibits vasoconstriction and aldosterone secretion, resulting in vasodilation and reduction of blood pressure. This mechanism helps to decrease the risk of stroke, myocardial infarction, and cardiovascular mortality in patients with hypertension or high cardiovascular risk. Hexartan 80 is typically administered once daily, with or without food, and dosage adjustments may be necessary based on patient response and clinical condition. It is contraindicated in patients with hypersensitivity to Telmisartan or any component of the formulation, and caution is advised in individuals with renal impairment, hepatic dysfunction, or volume depletion. Common adverse effects include dizziness, hypotension, and fatigue, while serious adverse events are rare but may involve hyperkalemia or renal function deterioration. Regular monitoring of blood pressure, renal function, and electrolytes is recommended during therapy. Hexartan 80 should not be used during pregnancy due to potential fetal toxicity. This medication is an effective option for managing hypertension and reducing cardiovascular risk when used as part of a comprehensive treatment plan under medical supervision.
