Propranolol mechanism of action for migraines
WebbMigraine headache is associated with trigeminal nerve activation and calcitonin gene-related peptide (CGRP) release from the trigeminovascular system. Administration of triptans (5-HT(1B/1D) receptor agonists) causes the headache to subside and the levels of CGRP to normalize. Webbwith migraine treated for cardiovascular dis- ease with propranolol, a beta-adrenergic re- ceptor blocker. These observations coupled with our experimental results of propranolol's effects on cerebral blood flow and metabolism* prompted a controlled study on the efficacy of this substance as a modifier of the migraine
