Losacar 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 effectively reduces vasoconstriction and aldosterone secretion, leading to decreased blood pressure and improved cardiovascular outcomes. This medication is indicated for the treatment of essential hypertension, helping to prevent stroke, myocardial infarction, and renal complications associated with high blood pressure. Losacar 25 may also be prescribed for patients with diabetic nephropathy to slow the progression of kidney damage. The tablet is administered orally, typically once daily, with or without food, as directed by a healthcare professional. Common side effects include dizziness, headache, and fatigue, while serious adverse reactions are rare but may include hyperkalemia and renal impairment. Caution is advised in patients with renal or hepatic dysfunction, and it is contraindicated during pregnancy due to potential fetal harm. Regular monitoring of blood pressure, renal function, and electrolyte levels is recommended during therapy. Losacar 25 Tablet should be used under medical supervision to ensure optimal therapeutic efficacy and safety.
