Nifedipine works by inhibiting the influx of calcium ions into cardiac and smooth muscle cells. This action results in the relaxation of blood vessels, which in turn reduces the workload on the heart and lowers blood pressure. By decreasing the force of contraction in the heart muscle, Nifedipine effectively alleviates symptoms of angina and helps in managing hypertension.

In what forms is Nifedipine available?

Nifedipine is available in several dosage forms, including immediate-release tablets and extended-release tablets.
