Mechanism of action

Variant angina (Prinzmetal's angina) is caused by episodic coronary artery vasospasm. Calcium channel blockers inhibit L-type calcium channels in vascular smooth muscle, preventing the influx of calcium ions that triggers vasoconstriction. This reduces the frequency and severity of vasospastic episodes and relieves anginal chest pain.
