A 2014 Cochrane review has shown that zolmitriptan 5mg nasal spray was significantly more effective than the 5mg oral tablet.[9]
Contraindications
Zolmitriptan is contraindicated in patients with cerebrovascular or cardiovascular disease because serotonin5-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]
There is limited experience with overdose of zolmitriptan and there is no specific antidote for zolmitriptan overdose.[4] A dose of zolmitriptan of 50mg, which is 10- to 40-fold the clinically used dose range of 1.25 to 5mg, commonly resulted in sedation in patients in a clinical study.[4] Zolmitriptan has a relatively short elimination half-life of 3hours, and so symptoms of overdose may be expected to resolve within around 15hours post-intake.[4]
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]
Zolmitriptan has a rapid onset of action and has been detected in the brain as early as within 5minutes of intranasal administration. On average, zolmitriptan has an oralbioavailability of 40%, a mean volume of distribution of 8.3L/kg after oral administration, and 2.4L/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.[28]
The experimental log P of zolmitriptan is 1.6 to 1.8.[5][34] For comparison, the experimental log P of sumatriptan is 0.8 to 0.93.[35][34] Zolmitriptan is much more lipophilic than sumatriptan.[12][34]
Zolmitriptan is marketed by AstraZeneca with the brand names Zomig, Zomigon (Argentina, Canada, and Greece), AscoTop (Germany) and Zomigoro (France).
Economics
In 2008, Zomig generated nearly $154 million in sales.[40]
AstraZeneca's U.S. patent on Zomig tablets expired on November 14, 2012, and its pediatric exclusivity extension expired on May 14, 2013.[41] 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.[42]
Legal status
In Russia, versions of zolmitriptan which are not registered in the National registry of medications may be regarded as narcotic drugs (derivatives of dimethyltriptamine).[43]

[...] 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).

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.

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).

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).
