Patient summary

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.
