Losium 25 Tablet contains Losartan 25 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, Losartan 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 renal impairment. Losium 25 is also indicated for the treatment of diabetic nephropathy in patients with type 2 diabetes and hypertension, as it helps to reduce proteinuria and slow the progression of kidney damage. The tablet is typically administered orally once daily, with or without food, and dosage adjustments may be required based on clinical response and patient tolerance. Common adverse effects include dizziness, fatigue, and upper respiratory infections, while serious side effects are rare but may include hyperkalemia and renal function impairment. Losium 25 should be used cautiously in patients with hepatic or renal impairment and is contraindicated during pregnancy due to potential teratogenic effects. Regular monitoring of blood pressure, renal function, and electrolytes is recommended during therapy to ensure safety and efficacy.
