Zolmitriptan is marketed by AstraZeneca with the brand names Zomig, Zomigon (Argentina, Canada & Greece), AscoTop (Germany) and Zomigoro (France). In 2008, Zomig generated nearly $154 million in sales.
AstraZeneca's U.S. patent on Zomig tablets expired on November 14, 2012, and its pediatric exclusivity extension expired on May 14, 2013. 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.
Zolmitriptan is used for the acute treatment of migraines with or without aura in adults. Zolmitriptan is not intended for the prophylactic therapy of migraine or for use in the management of hemiplegic or basilar migraine.
Zolmitriptan is available as a swallowable tablet, an oral disintegrating tablet, and 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), which contains aspartame.
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. 
Zolmitriptan may increase blood pressure, it should not be given to patients with uncontrolled hypertension, should not be used within 24 hours of treatment with another 5-HT1 agonist, or an ergotamine-containing or ergot-type medication like dihydroergotamine or methysergide, and should not be administered to patients with hemiplegic or basilar migraine.
Concurrent administration of MAOI or use of zolmitriptan within 2 weeks of discontinuation of MAO-A inhibitor therapy is contraindicated.
Drug Interactions: see Zomig package insert for complete list: 
Following administration of cimetidine, the half-life and AUC of zolmitriptan and its active metabolites were approximately doubled (see CLINICAL PHARMACOLOGY in product pamphlet). Cimetidine (INN) (/sɨˈmɛtɨdiːn/ or /saɪˈmɛtɨdiːn/) is a histamine H2-receptor antagonist that inhibits the production of acid in the stomach.
