Opioids are not recommended for treatment of acute migraines due to their significant side effect profile, including twice the risk of medication overuse headache when compared to NSAIDS, acetaminophen or triptans. [3] In addition, their strength of efficacy has showed to be low or insufficient for pain relief of migraines. [3]
The most common side effects [14] reported by at least 2% of patients in controlled trials of sumatriptan (25-, 50-, and 100-mg tablets) for migraine are atypical sensations (paresthesias and warm/cold sensations) reported by 4% in the placebo group and 5–6% in the sumatriptan groups, pain and other pressure sensations (including chest pain ...
Nausea is a common side effect. [8] It has similar actions to the triptans, acting as an agonist to the serotonin receptors and causing vasoconstriction of the intracranial blood vessels, but also interacts centrally with dopamine and adrenergic receptors. It can be used to treat acute intractable headache or withdrawal from analgesics.
Often, patients can only recognize their prodrome symptoms when they get to the pain phase and look back, Singh says. During a prodrome period, the Mayo Clinic and American Migraine Foundation say ...
Eletriptan blocks the release of substances from nerve endings that cause more pain and other symptoms like nausea, and sensitivity to light and sound. It is thought that these actions contribute to relief of symptoms by eletriptan. Eletriptan is a serotonin receptor agonist, specifically an agonist of certain 5-HT 1 family receptors.
[5] [6] The risk of triptan side effects is also in general low, according to a systematic review. [7] Side effects include: sensations of warmth/heat, dizziness, drowsiness, tingling of the hands or feet, nausea, dry mouth and unsteadiness, chest pain/pressure, throat pain/pressure, unusually fast/slow/irregular pulse, and mental/mood changes. [6]
Triptans are a mid-line treatment suitable for many migraineurs with typical attacks. They may not work for atypical or unusually severe migraine attacks, transformed migraine, or status migrainosus (continuous migraine). Triptans are highly effective, reducing the symptoms or aborting the attack within 30 to 90 minutes in 70–80% of patients. [6]
The neurotransmitter serotonin (illustration) has various receptors. A serotonin receptor agonist is an agonist of one or more serotonin receptors. They activate serotonin receptors in a manner similar to that of serotonin (5-hydroxytryptamine; 5-HT), a neurotransmitter and hormone and the endogenous ligand of the serotonin receptors.
