Eritel 80-AM Tablet is a combination antihypertensive medication containing Telmisartan 80 mg and Amlodipine 5 mg. Telmisartan is an angiotensin II receptor blocker (ARB) that selectively inhibits the binding of angiotensin II to the AT1 receptor, thereby preventing vasoconstriction and aldosterone secretion, which leads to a reduction in blood pressure. Amlodipine is a dihydropyridine calcium channel blocker that inhibits the influx of calcium ions into vascular smooth muscle and cardiac muscle, resulting in vasodilation and decreased peripheral resistance. The synergistic action of these two agents effectively lowers blood pressure in patients with essential hypertension, improving cardiovascular outcomes and reducing the risk of stroke, myocardial infarction, and renal complications. Eritel 80-AM is indicated for the management of hypertension in patients who require combination therapy for adequate blood pressure control. It is generally well tolerated, with common adverse effects including peripheral edema, dizziness, and headache. This combination tablet offers the convenience of once-daily dosing, enhancing patient compliance. Eritel 80-AM should be used under medical supervision, with periodic monitoring of blood pressure, renal function, and electrolytes to ensure safety and efficacy. It is contraindicated in patients with hypersensitivity to its components and should be used cautiously in those with hepatic or renal impairment.
