Veracal 80 mg is a sustained-release tablet containing 80 mg of verapamil hydrochloride, a calcium channel blocker used to treat cardiovascular conditions. It works by inhibiting calcium ion influx into cardiac and smooth muscle cells, leading to vasodilation, reduced heart rate, and decreased myocardial oxygen demand. This makes it effective in managing essential hypertension, preventing angina pectoris, and controlling certain supraventricular arrhythmias. The tablet is designed for once- or twice-daily dosing, depending on the specific condition being treated. Common side effects include constipation, dizziness, headache, and bradycardia. Veracal should be used with caution in patients with heart failure, AV block, or low blood pressure. It is important to follow the prescribed dosage and consult a healthcare provider for proper management.
