Dihydroergotamine is a derivative of ergotamine and an agonist of the serotonin (5-HT) receptor subtypes 5-HT1B and 5-HT1D (Kis = 0.3 and 2.5 nM, respectively, for human receptors).{41322} It binds to dopamine D2 and D3 as well as 5-HT2A receptors (K0.5s = 5, 16, and 38 nM, respectively) but has lower affinity for D1, 5-HT2C, and 5-HT3 receptors (K0.5s = 2,779, 298, and >10,000 nM, respectively).{41323} Dihydroergotamine also binds to α-adrenergic receptors.{41324} Dihydroergotamine (50 and 100 mg/kg) increases the mechanical pain threshold in a rat model of neuropathic pain following chronic constriction injury to the infraorbital nerve. Formulations containing dihydroergotamine have been used in the treatment of migraine headaches.{41321}
