RELPAX (eletriptan hydrobromide)
RELPAX (eletriptan hydrobromide) is a serotonin (5-HT 1B/1D) receptor agonist indicated for the acute treatment of migraine with or without aura in adults. The medication is intended for use only after a clear diagnosis of migraine has been established and is not indicated for the preventive treatment of migraines or for cluster headaches. If a patient does not respond to the initial treatment, the diagnosis should be reconsidered before further administration.
How RELPAX Works
RELPAX functions as an agonist at 5-HT 1B/1D receptors located on intracranial blood vessels and sensory nerves within the trigeminal system. By activating these receptors, the drug promotes the constriction of cranial vessels and inhibits the release of pro-inflammatory neuropeptides. These actions counteract the local cranial vasodilation and neuropeptide release thought to be responsible for migraine symptoms.
