NCIt definition : The benzoate salt form of rizatriptan, a member of the triptan class agents with anti-migraine
property. Rizatriptan benzoate selectively binds to and activates serotonin (5-HT)
1B receptors expressed in intracranial arteries, and to 5-HT 1D receptors located
on peripheral trigeminal sensory nerve terminals in the meninges and central terminals
in brain stem sensory nuclei. Receptor binding results in constriction of cranial
vessels and inhibition of nociceptive transmission, thereby providing relief of migraine
headaches. Rizatriptan benzoate may also relief migraine headaches by inhibition of
pro-inflammatory neuropeptide release.;
