Zolmitriptan is a member of the triptan class of agents with anti-migraine properties. Zolmitriptan selectively binds to and activates serotonin (5-HT) 1B receptors expressed in intracranial arteries and 5-HT 1D receptors located on peripheral trigeminal sensory nerve terminals in the meninges and central terminals in brainstem sensory nuclei. Receptor binding results in constriction of cranial vessels, reduction of vessel pulsation and inhibition of nociceptive transmission, thereby providing relief of migraine headaches. Zolmitriptan may also relieve migraine headaches by inhibition of pro-inflammatory neuropeptide release.
Zolmitriptan is a Serotonin-1b and Serotonin-1d Receptor Agonist. The mechanism of action of zolmitriptan is as a Serotonin 1b Receptor Agonist, and Serotonin 1d Receptor Agonist.

FDA Label


5 Pharmacology and Biochemistry
5.1 Pharmacology

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. Zolmitriptan is also 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. In addition, chest/throat/neck/jaw pain, tightness, and/or pressure has been reported, along with the possibility of medication overuse headaches and serotonin syndrome. Patients with phenylketonuria should be advised that ZOMIG-ZMT contains phenylalanine.

5.5 Absorption, Distribution and Excretion

Absorption

Zolmitriptan tablets have a mean absolute oral bioavailability of approximately 40%, with food having no effect on the rate or extent of absorption. The dosing kinetics are linear over a range of 2.5 to 50 mg with 75% of the eventual Cmax being attained within 1 hour of dosing. The median Tmax for the tablet form is 1.5 hours, while for the orally disintegrating tablet form, it is 3 hours. The AUC across studies was in the range of 84.4-173.8 ng/mL*h while the Cmax was between 16 and 25.2 ng/mL. Zolmitriptan administered as a nasal spray is detected in the plasma within 2-5 minutes, compared to 10-15 minutes for the tablet form; the faster kinetics likely reflect fast absorption across the nasal mucosa. The bioavailability compared to the tablet is 102%, and plasma zolmitriptan concentration is maintained for 4-6 hours after intranasal delivery. The active N-desmethyl metabolite of zolmitriptan has a mean plasma concentration that is roughly two-thirds of zolmitriptan, regardless of dosage route or concentration.


Route of Elimination

Zolmitriptan is primarily excreted in urine (approximately 65%) and feces (approximately 30%). Within urine, the most common form is the indole acetic acid metabolite (31%), followed by the N-oxide (7%), and N-desmethyl (4%) metabolites; the majority of zolmitriptan recovered in feces remains unchanged.


Volume of Distribution

Zolmitriptan has a volume of distribution between 7 and 8.4 L/kg.


Clearance

Zolmitriptan has a clearance of 31.5 mL/min/kg for oral tablets and 25.9 mL/min/kg for nasal administration; one-sixth of the clearance is renal.


5.6 Metabolism/Metabolites

Zolmitriptan is metabolized in the liver, and studies using cytochrome P450 inhibitors like [cimetidine] suggest that it is likely metabolized by CYP1A2, as well as by monoamine oxidase (MAO). Zolmitriptan metabolism results in three major metabolites: an active N-desmethyl metabolite (183C91) as well as inactive N-oxide (1652W92) and indole acetic acid (2161W92) metabolites.


Zolmitriptan has known human metabolites that include N-Desmethylzolmitriptan and Zolmitriptan N-oxide.

S73 | METXBIODB | Metabolite Reaction Database from BioTransformer | DOI:10.5281/zenodo.4056560


5.7 Biological Half-Life

Zolmitriptan has a mean elimination half-life of approximately three hours, while its active N-desmethyl metabolite has a slightly longer (approximately 3.5 hours) half-life.


5.8 Mechanism of Action

Migraines are complex physiological events characterized by unilateral throbbing headaches combined with photophobia and other aversions to sensory input. Migraine attacks are generally divided into phases: the premonitory phase, which typically involves irritability, fatigue, yawning, and stiff neck; the headache phase, which lasts for between four and 72 hours; and the postdrome phase, which lasts for up to a day following resolution of pain and whose symptoms are similar to those of the premonitory phase. In addition, neurological deficits, collectively termed migraine aura, may precede the headache phase. The underlying pathophysiology of migraines is a matter of active research but involves both neurological and vascular components. The head pain associated with migraine is thought to be a consequence of activation of the nociceptive nerves comprising the trigeminocervical complex (TCC). Terminals of nociceptive nerves that innervate the dura matter release vasoactive peptides, such as calcitonin gene-related peptide (CGRP), resulting in cranial vasodilation. Finally, when present, migraine aura appears to correlate with a transient wave(s) of cortical depolarization, termed cortical spreading depression (CSD). Triptans, including zolmitriptan, are proposed to act in three ways. The main mechanism is through modulation of nociceptive nerve signalling in the central nervous system through 5-HT1B/1D receptors throughout the TCC and associated areas of the brain. In addition, triptans can enhance vasoconstriction, both through direct 5-HT1B-mediated dilation of cranial blood vessels, as well as through 5-HT1D-mediated suppression of CGRP release. Although triptans are classically described solely in terms of their effects on 5-HT1B/1D receptors, they also act as 5-HT1F agonists as well. This 5-HT subtype is also found throughout the TCC, but is not present appreciably in cerebral vasculature; the significance of triptan-mediated 5-HT1F activation is currently not well described. Additionally, CSD that initiates in the ipsilateral parietal region may exert its effects in a manner that relies on 5-HT1B/1D receptor activation, suggesting that triptans may have some effect on CSD-mediated symptoms.
