Zolmitriptan, like other triptans, is a serotonin (5-hydroxytryptamine; 5-HT) receptor agonist, with enhanced specificity for the 5-HT1B and 5-HT1D receptor subtypes. It is through the downstream effects of 5-HT1B/1D activation that triptans are proposed to provide acute relief of migraines. It has a weak affinity for 5-HT 1A receptor. Zolmitriptan is a vasoconstrictor, leading to possible adverse cardiovascular effects such as myocardial ischemia/infarction, arrhythmias, cerebral and subarachnoid hemorrhage, stroke, gastrointestinal ischemia, and peripheral vasospastic reactions.
