K-Cor 10 Tablet contains Nicorandil 10 mg, a potent vasodilatory agent primarily indicated for the management of angina pectoris. Nicorandil acts through a dual mechanism: it functions as a nitrate donor, releasing nitric oxide which induces vasodilation of the coronary arteries, and it activates ATP-sensitive potassium channels in vascular smooth muscle, leading to hyperpolarization and relaxation of vascular tone. This combined action results in improved myocardial oxygen supply and reduced cardiac workload by decreasing both preload and afterload. K-Cor 10 is effective in the prevention and treatment of chronic stable angina and is particularly beneficial in patients who remain symptomatic despite conventional anti-anginal therapy. The tablet is administered orally, typically once or twice daily, with dosage adjustments based on clinical response and tolerability. Common adverse effects may include headache, dizziness, flushing, and gastrointestinal disturbances, which are generally mild and transient. Caution is advised in patients with hypotension, severe renal or hepatic impairment, and those concurrently using other vasodilators or phosphodiesterase inhibitors. K-Cor 10 should be prescribed under medical supervision, with regular monitoring of blood pressure and symptomatology to optimize therapeutic outcomes and ensure patient safety.
