Xartus 40 Tablet contains Telmisartan 40 mg, an angiotensin II receptor blocker (ARB) primarily indicated for the management of hypertension. By selectively inhibiting the binding of angiotensin II to the AT1 receptor, Telmisartan promotes vasodilation, thereby reducing peripheral vascular resistance and lowering blood pressure. This mechanism helps prevent complications associated with hypertension, such as stroke, myocardial infarction, and kidney damage. Xartus 40 is also utilized in reducing cardiovascular risk in patients with a history of coronary artery disease or those intolerant to angiotensin-converting enzyme (ACE) inhibitors. The tablet is administered orally, typically once daily, with or without food, and dosage adjustments may be necessary based on clinical response and renal function. Common adverse effects include dizziness, headache, and fatigue, while serious side effects are rare but may involve hyperkalemia and renal impairment. Contraindications include hypersensitivity to Telmisartan or any tablet components, and caution is advised in patients with bilateral renal artery stenosis or severe hepatic impairment. Regular monitoring of blood pressure, renal function, and electrolytes is recommended during therapy. Xartus 40 Tablet should be used under medical supervision to ensure optimal therapeutic outcomes and minimize potential risks.
