Eritel 80 Tablet contains Telmisartan 80 mg, an angiotensin II receptor antagonist used primarily for the management of hypertension. By selectively blocking the binding of angiotensin II to the AT1 receptor in vascular smooth muscle, Telmisartan promotes vasodilation, thereby reducing peripheral vascular resistance and lowering blood pressure. This mechanism helps prevent complications associated with hypertension, including stroke, myocardial infarction, and renal impairment. Eritel 80 is indicated for the treatment of essential hypertension and may be used alone or in combination with other antihypertensive agents to achieve optimal blood pressure control. The tablet is typically administered once daily, with or without food, to enhance patient compliance. Telmisartan is also beneficial in reducing cardiovascular risk in patients with high cardiovascular risk factors. Common side effects include dizziness, headache, and fatigue, though it is generally well tolerated. Caution is advised in patients with impaired renal or hepatic function, and it is contraindicated during pregnancy due to potential fetal toxicity. Regular monitoring of blood pressure, renal function, and electrolytes is recommended during therapy. Eritel 80 Tablet offers an effective and well-established option for long-term hypertension management under medical supervision.
