Dihydroergotamine (/dˌhdr.ɜrˈɡɒtəmn/ dy-hy-droh-ur-got-ə-meen; brand names D.H.E. 45 and Migranal) is an ergot alkaloid used to treat migraines. It is a derivative of ergotamine. It is administered as a nasal spray or injection and has an efficacy similar to that of sumatriptan. Nausea is a common side effect.

It has similar actions to the triptans but also interacts centrally with dopamine and adrenergic receptors. It can be used to treat acute intractable headache or withdrawal from analgesics.

Description

Dihydroergotamine (DHE) is a semi-synthetic form of ergotamine approved in the US in 1946. Oral bioavailability is poor and it is not available in oral form in the US. DHE is available as Migranal nasal spray and in ampules for subcutaneous, intramuscular and intravenous injection. Efficacy is variable in the nasal spray form with bioavailability 32% of injectable administration. Subcutaneous and intramuscular injections are generally more effective than the nasal spray and can be self-administered by patients. Intravenous injection is considered very effective for severe migraine or status migrainosus. DHE is also used in the treatment of medication overuse headache.

Nausea is a common side effect of IV administration and less common in other modes. Antiemetics can be given prior to DHE to counteract the nausea. Risks and contraindications are similar to the triptans. DHE and triptans should not be taken within 24 hours of each other due to the potential for coronary artery vasospasm. DHE produces no dependence.[1]

MAP Pharmaceuticals submitted an inhaled version of DHE (Levadex) for FDA approval in May 2011.
