LONITAB 2 5MG TAB

About

Minoxidil is a potent direct-acting peripheral vasodilator primarily utilized in the management of severe, refractory hypertension that has not responded adequately to conventional antihypertensive regimens. Its mechanism involves the opening of ATP-sensitive potassium channels in vascular smooth muscle cells, leading to hyperpolarization and subsequent relaxation of arterial walls. This reduction in peripheral vascular resistance effectively lowers both systolic and diastolic blood pressure. However, this potent vasodilatory action often triggers reflex tachycardia and significant fluid retention, necessitating co-administration with a beta-blocker to control heart rate and a diuretic to manage edema. Due to its pronounced side effect profile, including the potential for pericardial effusion and hypertrichosis, its use is generally reserved for patients with severe, life-threatening hypertension where other treatments have failed or are contraindicated. Careful patient selection and close monitoring are crucial during therapy.

Uses

• Management of severe hypertension.
• Treatment of refractory hypertension.

Safety Measures

• Alcohol - Avoid or limit alcohol consumption as it can exacerbate hypotensive effects and dizziness.

• Liver - Use with caution in patients with liver impairment as metabolism may be affected; dose adjustment might be necessary.
• Kidney - Use with caution in patients with kidney disease, especially those with fluid retention; close monitoring of fluid and electrolyte balance is crucial.
• Lung - No specific contraindications related to lung conditions, but monitor for fluid overload which can worsen pulmonary edema.
