FDA Drug Information
Indications & Usage
1 INDICATIONS AND USAGE Sumatriptan injection is indicated in adults for (1) the acute treatment of migraine, with or without aura, and (2) the acute treatment of cluster headache. Limitations of Use: Use only if a clear diagnosis of migraine or cluster headache has been established. If a patient has no response to the first migraine or cluster headache attack treated with sumatriptan injection, reconsider the diagnosis before sumatriptan injection is administered to treat any subsequent attacks. Sumatriptan injection is not indicated for the prevention of migraine or cluster headache attacks. Sumatriptan injection is a serotonin (5-HT 1B/1D ) receptor agonist (triptan) indicated for: Acute…
Mechanism of Action
12.1 Mechanism of Action Sumatriptan binds with high affinity to human cloned 5-HT 1B/1D receptors. Sumatriptan presumably exerts its therapeutic effects in the treatment of migraine and cluster headaches through agonist effects at the 5-HT 1B/1D receptors on intracranial blood vessels and sensory nerves of the trigeminal system, which result in cranial vessel constriction and inhibition of pro-inflammatory neuropeptide release.

Drug Interactions
7 DRUG INTERACTIONS 7.1 Ergot-Containing Drugs Ergot-containing drugs have been reported to cause prolonged vasospastic reactions. Because these effects may be additive, use of ergotamine-containing or ergot-type medications (like dihydroergotamine or methysergide) and sumatriptan injection within 24 hours of each other is contraindicated. 7.2 Monoamine Oxidase-A Inhibitors MAO-A inhibitors increase systemic exposure by 2-fold. Therefore, the use of sumatriptan injection in patients receiving MA…
