Lonitab 5 Tablet contains Minoxidil 5 mg, a potent vasodilator primarily indicated for the treatment of hypertension that is resistant to conventional therapy. Minoxidil works by directly relaxing vascular smooth muscle, leading to peripheral vasodilation and a consequent reduction in systemic vascular resistance, which effectively lowers blood pressure. This medication is typically reserved for patients who have not achieved adequate blood pressure control with standard antihypertensive agents such as diuretics, beta-blockers, or ACE inhibitors. Lonitab 5 Tablet should be administered under strict medical supervision due to its potent pharmacological effects and potential for adverse reactions. Common side effects may include hypertrichosis, tachycardia, fluid retention, and pericardial effusion; therefore, concurrent use of a beta-blocker and a diuretic is often recommended to mitigate these risks. It is contraindicated in patients with pheochromocytoma and hypersensitivity to Minoxidil. Regular monitoring of blood pressure, heart rate, and electrolyte levels is essential during therapy. Patients should be advised to adhere to prescribed dosages and report any unusual symptoms promptly. Lonitab 5 Tablet offers an effective option for managing severe hypertension when used as part of a comprehensive treatment regimen.
