Zolmitriptan, sold under the brand name Zomig among others, is a serotonergic medication which is used in the acute treatment of migraine attacks with or without aura and cluster headaches. [4] It is taken by mouth as a swallowed or disintegrating tablet or as a nasal spray. [4]
Side effects include tightness in the neck or throat, jaw pain, dizziness, paresthesia, asthenia, somnolence, warm/cold sensations, nausea, chest pressure, and dry mouth. [4] The drug acts as a selective serotonin 5-HT1B and 5-HT1D receptor agonist. [4] Structurally, it is a triptan and a tryptamine derivative. [4] [5]
It was patented in 1990 and was approved for medical use in 1997. [6] [4]
Zolmitriptan is used for the acute treatment of migraines with or without aura in adults. [4] It is not intended for the prophylactic therapy of migraine or for use in the management of hemiplegic or basilar migraine. [4]
Zolmitriptan is available as a swallowed tablet, an orally disintegrating tablet, and as a nasal spray, in doses of 2.5 and 5 mg. People who get migraines from aspartame should not use the disintegrating tablet (Zomig ZMT) as it contains aspartame. [8]
A 2014 Cochrane review has shown that zolmitriptan 5 mg nasal spray was significantly more effective than the 5 mg oral tablet. [9]
Zolmitriptan is contraindicated in patients with cerebrovascular or cardiovascular disease because serotonin 5-HT1B receptors are present in coronary arteries. Such conditions include, but are not limited to, coronary artery disease, stroke, and peripheral vascular disease. [7] It is also contraindicated in hemiplegic migraine. [7]
Side effects include neck/throat/jaw pain/tightness/pressure, dizziness, paresthesia, asthenia, somnolence, warm/cold sensations, nausea, heaviness sensation, and dry mouth. [4]
As for cardiovascular side effects, zolmitriptan can increase systolic blood pressure in the elderly and increase diastolic blood pressure in both the elderly and young people. Additionally, there is the side effect of a dose-related increase in sedation. There is a risk for medication withdrawal headache or medication overuse headache. [7]
Zolmitriptan has a weak affinity for serotonin 5-HT1A receptors; these receptors have been implicated in the development of serotonin syndrome. [7]
There is limited experience with overdose of zolmitriptan and there is no specific antidote for zolmitriptan overdose. [4] A dose of zolmitriptan of 50 mg, which is 10- to 40-fold the clinically used dose range of 1.25 to 5 mg, commonly resulted in sedation in patients in a clinical study. [4] Zolmitriptan has a relatively short elimination half-life of 3 hours, and so symptoms of overdose may be expected to resolve within around 15 hours post-intake. [4]
Following administration of the non-selective cytochrome P450 inhibitor cimetidine, the elimination half-life and total exposure of zolmitriptan and its active metabolite were approximately doubled. [7] The major metabolite of zolmitriptan, N-desmethylzolmitriptan (183C91), which is active and has several-fold greater affinity for the serotonin 5-HT1B and 5-HT1D receptors than zolmitriptan, is metabolized into an inactive form by monoamine oxidase A (MAO-A). [3] The reversible inhibitor of MAO-A (RIMA) moclobemide combined with zolmitriptan has been found to increase N-desmethylzolmitriptan exposure and peak levels by 1.5- to 3-fold. [3]

Zolmitriptan is a selective serotonin 5-HT1B and 5-HT1D receptor agonist with weak affinity for the serotonin 5-HT1A receptor. [12] It also has affinity for other serotonin receptors, including the serotonin 5-HT1E, 5-HT1F, 5-HT2B, 5-HT5A, and 5-HT7 receptors. [12] Conversely, its affinities for the serotonin 5-HT2A, 5-HT2C, 5-HT3, 5-HT4, and 5-HT6 receptors are negligible or undetectable. [12] [22] It is likewise inactive as a serotonin 5-HT2A receptor agonist. [22]
Zolmitriptan's major metabolite, N-desmethylzolmitriptan (183C91), is also active and has about 2- to 6-fold the affinity of zolmitriptan for the serotonin 5-HT1B and 5-HT1D receptors. [3]
Its action on serotonin 5-HT1B and 5-HT1D receptors causes vasoconstriction in intracranial blood vessels; as well it can inhibit the release of pro-inflammatory neuropeptides from trigeminal perivascular nerve endings. It crosses the blood–brain barrier as evidenced by the presence of radiolabeled zolmitriptan within the cells of the trigeminal nucleus caudalis and nucleus tractus solitarii. [7]
Zolmitriptan has a rapid onset of action and has been detected in the brain as early as within 5 minutes of intranasal administration. On average, zolmitriptan has an oral bioavailability of 40%, a mean volume of distribution of 8.3 L/kg after oral administration, and 2.4 L/kg after intravenous administration. [7] According to a study of healthy volunteers, food intake seems to have no significant effect on the effectiveness of zolmitriptan in both men and women. [27]
Zolmitriptan is a more lipophilic compound with greater central permeability than certain other triptans like sumatriptan. [28] [29] It has been found to cross the blood–brain barrier and enter the central nervous system both in animals and humans. [30] In a clinical pharmacokinetic study, brain concentrations were about 20% of plasma concentrations. [31] However, in another clinical study, the drug achieved relatively low occupancy of central serotonin 5-HT1B receptors (4–5%) as measured by positron emission tomography (PET) imaging. [30] [32] [31]
Zolmitriptan is metabolized into three major metabolites by the human hepatic cytochrome P450 enzymes—primarily CYP1A2. Two-thirds of the parent compound breaks down into the active metabolite N-desmethylzolmitriptan (183C91), while the remaining one-third separates into the other two inactive metabolites: zolmitriptan N-oxide and an indole acetic acid derivative. [3] N-Desmethylzolmitriptan circulates at higher levels than those of zolmitriptan. [3] This metabolite is deaminated by monoamine oxidase A (MAO-A). [3]
Zolmitriptan has an elimination half-life of about 3 hours before it undergoes renal elimination; its clearance is greater than the glomerular filtration rate suggesting that there is some renal tubular secretion of the compound. [7]
Zolmitriptan, also known as [(4S)-2-oxo-1,3-oxazolidin-4-yl]methyl-N,N-dimethyltryptamine, is a tryptamine derivative and a 5-substituted derivative of the psychedelic drug dimethyltryptamine (DMT). [4] [5] It is specifically the derivative of DMT in which the hydrogen atom at position 5 of the indole ring has been substituted with a [(4S)-2-oxo-1,3-oxazolidin-4-yl]methyl group. [5]
The experimental log P of zolmitriptan is 1.6 to 1.8. [5] [33] For comparison, the experimental log P of sumatriptan is 0.8 to 0.93. [34] [33] Zolmitriptan is much more lipophilic than sumatriptan. [12] [33]
Analogues of zolmitriptan include other triptans like sumatriptan, naratriptan, rizatriptan, eletriptan, almotriptan, and frovatriptan. [12] [33]
Zolmitriptan was patented in 1990 [6] and was first described in the scientific literature by 1994. [35] [36] [37] It was first introduced for medical use in the United States in 1997. [6] [4] [38]
Zolmitriptan is marketed by AstraZeneca with the brand names Zomig, Zomigon (Argentina, Canada, and Greece), AscoTop (Germany) and Zomigoro (France).
In 2008, Zomig generated nearly $154 million in sales. [39]
AstraZeneca's U.S. patent on Zomig tablets expired on November 14, 2012, and its pediatric exclusivity extension expired on May 14, 2013. [40] The patent in certain European countries has already expired too, and generic drug maker Actavis released a generic version in those countries, starting in March 2012. [41]
In Russia, versions of zolmitriptan which are not registered in the National registry of medications may be regarded as narcotic drugs (derivatives of dimethyltriptamine). [42]
Zolmitriptan showed no effect on obsessive–compulsive disorder (OCD) symptoms nor on mood or anxiety in a clinical study. [43] [44]
Zolmitriptan, in a modified-release formulation with code name ML-004 (or ML004), is under development by MapLight Therapeutics for the treatment of pervasive developmental disorders (e.g., autism), agitation, and aggression. [45] [46] [47] [48] [49] [50] The drug has been found to reduce aggression in rodents [51] [52] [53] and has also been reported to decrease aggression in humans. [54] [55] As of June 2023, zolmitriptan is in phase 2 clinical trials for pervasive developmental disorders, phase 1 clinical trials for agitation, and is in the preclinical stage of development for aggression. [45] [46] [47]
[...] the N-demethylated metabolites from zolmitriptan and eletriptan are both active at the 5-HT1B/1D sites. In particular, the N-desmethyl-zolmitriptan acts on 5-HT1B/1D receptors with an affinity about two- to six-fold of that of zolmitriptan and its steady state concentration is also higher than the parent drug. Therefore, N-desmethyl-zolmitriptan may have important contribution to the overall zolmitriptan drug effects. This active metabolite undergoes selective MAO-A-mediated deamination metabolism, resulting in an inactive indole acetic acid derivative (21) (Fig. 3). Because zolmitriptan is extensively N-demethylated and N-desmethyl-zolmitriptan is primarily excreted via deamination, potent MAO-A inhibitors are anticipated to alter the pharmacokinetics of N-desmethyl-zolmitriptan in humans. Indeed, concurrent use of selective MAO-A inhibitor, moclobemide, has been shown to cause 1.5- to 3-fold increase in the systemic exposure (AUC) and peak drug concentration (Cmax) of N-desmethyl-zolmitriptan (25).

The central mechanisms of triptans are a subject of intense debate and have been investigated in several studies. Brain PET studies reported that zolmitriptan crosses the BBB and binds to central 5-HT1B receptors with relatively low occupancy (77,78). It is still unknown whether sumatriptan has a central effect.

Interest in 5-HT1B as a target for ASD is further evidenced by the ongoing Phase 2 clinical trial of ML-004, a modified release form of the 5-HT1B/1D agonist zolmitriptan, which is being evaluated for the treatment of social communication deficits in adolescent and adult subjects with ASD (NCT05081245).
Purpose: The purpose of this study is to find out whether ML-004, an extended-release version of zolmitriptan, can support with sociability and emotional regulation in adults with ASD.
In addition, the 5-HT1B receptors are of potential importance as target for treatment of different disorders such as depression, schizophrenia, Parkinson's disease, and impulsive disorders [133]. Drugs acting as agonists at 5- HT1B receptors, when administered systemically, potently and efficaciously inhibit several types of aggressive behavior in mice [17,135; and for review see 63]. Systemically administered 5-HT1B receptor agonists such as CP-94,253, ampirtoline and zolmitriptan exert anti-aggressive effects in mice with moderate or high levels of aggression, without impairing non-aggressive activities [17, 23, 129,135]. Further support for the significant role of this receptor subtype derives from the finding of increased aggression in mutant 129Sv mice lacking the 5-HT1B receptor gene [136, and see 137].
Using such an ethopharmacological approach in either rats or mice, it has recently been claimed that only certain specific 5-HT1A receptor agonists (i.e., alnespirone and S-15535; de Boer et al., 1999, 2000), a mixed 5-HT1A/1B receptor agonist (i.e., eltoprazine; Olivier et al., 1995) and several specific 5-HT1B receptor agonists (i.e., CGS12066b, CP-94,253, anpirtoline, zolmitriptan, sumatriptan; Bell and Hobson, 1994; Fish et al., 1999; De Almeida et al., 2001; Miczek et al., 2004) exert behavioral specific anti-aggressive effects. In particular, it was claimed that agonists acting on the 5-HT1B receptors have more selective anti-aggressive effects in mice than those acting on 5-HT1A receptors (Miczek et al., 2004; Olivier, 2004).
A high proportion of violent acts are committed under the influence of alcohol. Aggressive behaviour can also be primed in the mouse by exposure to alcohol (De Almeida et al. 2001). In findings that are consistent with our knowledge of the relationship between serotonin and aggression (Pihl and Lemarquand 1998), this impact of alcohol can be ameliorated by treatment with the 5-HT1B/1D receptor agonist zolmitriptan, an approved anti-migraine drug. However, these findings have seemingly been overlooked despite the consistency of rodent and human data (Gowin et al. 2010).
