Lizy 5 Tablet contains Lisinopril 5 mg, an angiotensin-converting enzyme (ACE) inhibitor used primarily in the management of hypertension and heart failure. By inhibiting the ACE enzyme, Lisinopril reduces the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor, thereby promoting vasodilation and lowering blood pressure. This mechanism helps decrease the workload on the heart and improves cardiac output. Lizy 5 is indicated for the treatment of essential hypertension, congestive heart failure, and for improving survival after myocardial infarction. It may also be prescribed for diabetic nephropathy to protect renal function. The usual dosage varies based on the patient’s condition and response, with careful titration recommended to minimize adverse effects. Common side effects include cough, dizziness, headache, and hyperkalemia. Rare but serious adverse reactions may involve angioedema and renal impairment. Patients with a history of hypersensitivity to ACE inhibitors or those with bilateral renal artery stenosis should avoid this medication. Regular monitoring of blood pressure, renal function, and electrolytes is advised during therapy. Lizy 5 should be used under medical supervision, with adherence to prescribed dosing to ensure optimal therapeutic outcomes and minimize risks.
