Actions 

Vasoconstriction: Drug is known for its very strong vasoconstrictive effect, mainly on the smooth muscles of blood vessels. It works as an agonist of 5-HT1B and 5-HT1D (serotonin receptors) in the walls of blood vessels, which results in their contraction. This vasoconstrictive effect is beneficial to ease the pain that comes with migraine and cluster headache. 

 Anti-inflammatory effects: This drug also possesses anti-inflammatory activity via inhibition of the release of pro-inflammatory cytokines and histamines. This action may also contribute to the relief of headaches and associated symptoms.

Pregnancy & breastfeeding: 

Pregnancy consideration: 

USFDA pregnancy category: Not assigned 

Breastfeeding warnings: 

Data about the excretion of the drug into human milk is not known 

Pregnancy category: 

  • Category A: well-controlled and satisfactory studies show no risk to the fetus in the first or later trimester. 
  • Category B: There was no evidence of risk to the fetus in animal studies, and there were not enough studies on pregnant women. 
  • Category C: There was evidence of risk of adverse effects in animal reproduction studies, and no adequate evidence in human studies must take care of potential risks in pregnant women. 
  • Category D: Adequate data with sufficient evidence of human fetal risk from various platforms, but despite the potential risk, and used only in emergency cases for potential benefits. 
  • Category X: Drugs listed in this category outweigh the risks over benefits. Hence, these categories of drugs need to be avoided by pregnant women. 
  • Category N: No data for the drug under this category is available. 

Pharmacology: 

Dihydroergotamine is a medication which belongs to a class of drugs known as ergot alkaloids and derived from a fungus called Claviceps purpurea. It is indicated as an abortive therapy in treating migraines. 

Pharmacodynamics: 

Dihydroergotamine (DHE) usage is recommended for the treatment of migraine headache with or without aura. Beside cluster headache episodes, DHE has its therapeutic effects, which supposedly include nervous and vascular mechanisms. As a serotonin agonist, DHE may help decrease the activity of the neurotransmitter glutamate, which is the trigeminal system that leads to cortical spreading depression and migraines. Furthermore, its serotonin agonist activity triggers the blood vessels to narrow, which can bring about the frequent side effect of tightness of the chest, and can possibly offer therapeutic advantages through the vasodilation action produced in response to the release of calcitonin gene-related peptide (CGRP) during migraine. 

Pharmacokinetics: 

Absorption: 

The bioavailability of the drug is found to be about 40% when administered intranasally. The absorption is poor in case of oral formulations due to first-pass metabolism. 100% bioavailability can be achieved when given through IV or IM. 

Distribution: 

The volume of distribution of the drug is found to be 800L. 93% of the drug is bound to plasma proteins. 

Metabolism: 

It undergoes hepatic metabolism and produces four metabolites of which 8-β-hydroxy dihydroergotamine is the active and major metabolite with potency equivalent to 5-HT and adrenergic receptors.  

Elimination/Excretion: 

It is eliminated primarily through biliary excretion. Less 10% of the drug is eliminated through urine and most of the drug is mainly excreted in feces. 

Half-life: It shows biphasic elimination half-lives with 0.7 to 1 hour and 10 to 13 hours.  

Administration: 

It can be administered as an IM, IV, or SC injection. For IV administration, 1 mg or a smaller portion should be given over a period of 1 minute. It is important to note that this medication is not suitable for regular, long-term use.
