Side effects include neck/throat/jaw pain/tightness/pressure, dizziness, paresthesia, asthenia, somnolence, warm/cold sensations, nausea, heaviness sensation, and dry mouth.[3] The drug acts as a selective serotonin 5-HT1B and 5-HT1D receptor agonist.[3] Structurally, it is a triptan and a tryptamine derivative.[3][4]

It was patented in 1990 and was approved for medical use in 1997.[5][3]

Medical uses

edit

Migraine

edit

Zolmitriptan is used for the acute treatment of migraines with or without aura in adults.[3] It is not intended for the prophylactic therapy of migraine or for use in the management of hemiplegic or basilar migraine.[3]

Off-label uses

edit

Available forms

edit

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.[7]

A 2014 Cochrane review has shown that zolmitriptan 5 mg nasal spray was significantly more effective than the 5 mg oral tablet.[8]

Contraindications

edit

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.[6] It is also contraindicated in hemiplegic migraine.[6]

Side effects

edit

Side effects include neck/throat/jaw pain/tightness/pressure, dizziness, paresthesia, asthenia, somnolence, warm/cold sensations, nausea, heaviness sensation, and dry mouth.[3]

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.[6]

Zolmitriptan has a weak affinity for serotonin 5-HT1A receptors; these receptors have been implicated in the development of serotonin syndrome.[6]

Interactions

edit

Following administration of cimetidine, the elimination half-life and total exposure of zolmitriptan and its active metabolite were approximately doubled.[6]

Pharmacology

edit

Mechanism of action

edit

Zolmitriptan is a selective serotonin 5-HT1B and 5-HT1D receptor agonist with weak affinity for the serotonin 5-HT1A receptor.[9] It also has affinity for other serotonin receptors, including the serotonin 5-HT1E, 5-HT1F, 5-HT2B, 5-HT5A, and 5-HT7 receptors.[9] Conversely, its affinities for the serotonin 5-HT2A, 5-HT2C, 5-HT3, 5-HT4, and 5-HT6 receptors are negligible or undetectable.[9]

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.[6]

Pharmacokinetics

edit

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 2.4L/kg after intravenous administration.[6] 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.[10]

Zolmitriptan is a more lipophilic compound with greater central permeability than certain other triptans like sumatriptan.[11][12] It has been found to cross the blood–brain barrier and enter the central nervous system both in animals and humans.[13] In a clinical pharmacokinetic study, brain concentrations were about 20% of plasma concentrations.[14] 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.[13][15][14]

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. It 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.[6]

Chemistry

edit

Zolmitriptan is a triptan and a substituted tryptamine.[3][4] It is specifically the derivative of N,N-dimethyltryptamine (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.[4]

The experimental log P of zolmitriptan is 1.6 to 1.8.[4] For comparison, the experimental log P of sumatriptan is 0.93.[16] It is much more lipophilic than sumatriptan.[9]

Analogues of zolmitriptan include other triptans like sumatriptan, naratriptan, rizatriptan, eletriptan, almotriptan, and frovatriptan.[9]

Society and culture

edit

Brand names

edit

Zolmitriptan is marketed by AstraZeneca with the brand names Zomig, Zomigon (Argentina, Canada & Greece), AscoTop (Germany) and Zomigoro (France).

Economics

edit

In 2008, Zomig generated nearly $154 million in sales.[17]

AstraZeneca's U.S. patent on Zomig tablets expired on November 14, 2012, and its pediatric exclusivity extension expired on May 14, 2013.[18] 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.[19]

edit

In Russia versions of zolmitriptan, which are not registered in the National registry of medications, may be regarded as narcotic drugs (derivatives of dimethyltriptamine).[20]

Research

Zolmitriptan, in a modified-release formulation that is being referred to by the developmental 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.[21][22][23][24][25][26] As of June 2023, it 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.[21][22][23]
