Calcium Channel Blockers

These agents inhibit the initial vasoconstrictive phase of CH.

Verapamil (Calan, Verelan, Verelan PM, Covera-SR)

Perhaps the most effective calcium channel blocker for CH prophylaxis, verapamil inhibits calcium ions from entering slow channels, select voltage-sensitive areas, or vascular smooth muscle, thereby producing vasodilation. It can be combined with ergotamine or lithium.
