Calcium-channel blocking agents and chest pain

Abstract

Calcium-channel blocking agents can relieve anginal and chest pain associated with hypermotility of the esophagus. Although calcium-channel antagonists differ in their effects on the esophageal body and the lower esophageal sphincter, reduction of lower esophageal sphincter pressure theoretically could result in gastroesophageal reflux and pain. This pain may be difficult to differentiate from chest pain of cardiac origin. An association between calcium-channel blocking agents and chest pain is speculative at this time. However, the possibility of such an effect should be considered by clinicians in the total management of patients. Future clinical studies are warranted to address the issue of the incidence of such an effect and to define more precisely the potential interrelationship among the calcium-channel antagonists, their efficacy in relieving cardiac pain, and their potential liability in inducing chest pain of noncardiac origin.
