Patient summary
utilized to alleviate hypertension and manage cardiac arrhythmias through systemic vascular resistance reduction.
Mechanism of action
Calan Sr acts as a calcium channel blocker, inhibiting the influx of calcium ions into cardiac and vascular smooth muscle cells. This process relaxes coronary arteries and systemic peripheral vessels, improving blood flow, reducing blood pressure, and slowing the heart rate, thereby decreasing the cardiac workload.
Pregnancy and breastfeeding
Pregnancy: Use only if clearly indicated and after risk assessment. Breastfeeding: Excreted in breast milk; monitor infants closely.
