Winpace 5 Tablet contains S-Amlodipine 5 mg, a calcium channel blocker primarily indicated for the management of hypertension and angina pectoris. S-Amlodipine, the pharmacologically active enantiomer of amlodipine, exerts its therapeutic effects by inhibiting the influx of calcium ions through L-type calcium channels in vascular smooth muscle and cardiac muscle. This action results in vasodilation, leading to a reduction in peripheral vascular resistance and subsequently lowering blood pressure. The drug also improves myocardial oxygen delivery by dilating coronary arteries and arterioles, making it effective in the treatment of stable and variant angina. Winpace 5 is typically administered once daily due to its long half-life, ensuring sustained blood pressure control over 24 hours. It is well-tolerated, with common adverse effects including peripheral edema, headache, dizziness, and flushing. Caution is advised in patients with severe hypotension, aortic stenosis, or heart failure. Dose adjustments may be necessary in hepatic impairment. Winpace 5 should be used under medical supervision, with regular monitoring of blood pressure and clinical response to optimize therapeutic outcomes and minimize potential side effects. It is contraindicated in patients with known hypersensitivity to amlodipine or other dihydropyridine calcium channel blockers.
