Eslo-Tel 5mg Tablet is a combination antihypertensive medication containing Telmisartan 40mg and Amlodipine 5mg. Telmisartan is an angiotensin II receptor antagonist that selectively blocks the binding of angiotensin II to the AT1 receptor, thereby inhibiting vasoconstriction and aldosterone secretion, which results in vasodilation and reduced blood pressure. Amlodipine is a calcium channel blocker that inhibits the influx of calcium ions into vascular smooth muscle and cardiac muscle, leading to relaxation of peripheral arterioles and decreased peripheral vascular resistance. The synergistic action of these two agents effectively lowers blood pressure in patients with essential hypertension, reducing the risk of cardiovascular events such as stroke and myocardial infarction. Eslo-Tel 5mg is indicated for the management of hypertension in patients who require combination therapy for optimal blood pressure control. It is generally well tolerated, with common adverse effects including dizziness, peripheral edema, and headache. Dosage should be individualized based on patient response and tolerability. Regular monitoring of blood pressure, renal function, and electrolytes is recommended during therapy. Eslo-Tel 5mg should be used under medical supervision, particularly in patients with hepatic or renal impairment, and is contraindicated in pregnancy and patients with known hypersensitivity to its components.
