DIHYDROERGOTAMINE MESYLATE
Dihydroergotamine Mesylate Injection is a pharmaceutical agent indicated for the acute treatment of migraine headaches, including cases with or without aura. It is also approved for the acute treatment of cluster headache episodes. The medication is intended for the immediate management of these conditions rather than for preventative use.
How DIHYDROERGOTAMINE MESYLATE Works
Dihydroergotamine acts as an agonist at the 5-HT1B, 5-HT1D, and 5-HT1F receptors. Its efficacy in treating migraine is attributed to two primary mechanisms: 1) activation of 5-HT1B receptors located on intracranial blood vessels, leading to vasoconstriction, and 2) activation of 5-HT1D receptors on sensory nerve endings of the trigeminal system, which inhibits the release of pro-inflammatory neuropeptides (such as calcitonin gene-related peptide, or CGRP). It also interacts with alpha-adrenergic and dopaminergic receptors, which contributes to its complex pharmacological profile and potential side effects.
