BREKIYA (AUTOINJECTOR)
Brekiya (dihydroergotamine mesylate) is an autoinjector indicated for the acute treatment of migraine headaches, with or without aura, and the acute treatment of cluster headache episodes in adults. It is intended for the immediate management of headache pain and is not indicated for the prophylactic therapy of migraine or cluster headaches.
How BREKIYA (AUTOINJECTOR) Works
Dihydroergotamine binds with high affinity to 5-HT1B, 5-HT1D, and 5-HT1F receptors. Its therapeutic efficacy in migraine is attributed to agonist activity at 5-HT1B and 5-HT1D receptors, which results in the constriction of inflamed intracranial blood vessels and the inhibition of pro-inflammatory neuropeptide release from trigeminal nerve endings. Dihydroergotamine also exhibits affinity for alpha-adrenergic and dopaminergic receptors.

PERIPHERAL ISCHEMIA FOLLOWING COADMINISTRATION WITH POTENT CYP3A4 INHIBITORS Serious and/or life-threatening peripheral ischemia has been associated with the co-administration of dihydroergotamine with potent CYP3A4 inhibitors including protease inhibitors and macrolide antibiotics. Because CYP3A4 inhibition elevates the serum levels of dihydroergotamine, the risk for vasospasm leading to cerebral ischemia and/or ischemia of the extremities is increased.
