Less common uses include prophylactic treatment of migraine headaches, treatment of arterial vasospasm due to Raynaud's disease, esophageal spasm, and pulmonary hypertension.1 For the last 50 years, CCBs have accounted for more poisoning deaths than any other cardiovascular drug and are the second most common cause of prescription drug poisoning death.
