Eletriptan (Relpax)- Dosage, Uses, and Side Effects

Eletriptan is used in the treatment of migraine. It narrows blood vessels around the brain and reduces the substance that triggers pain or migraine symptoms.

Migraine is of different types- with or without aura. Eletriptan is used to treat both. It is helpful if a migraine has started. It doesn’t reduce or prevent the attack.

Eletriptan should not be used in the treatment of headaches other than migraine. Only use this medication if a doctor has identified your symptoms as migraine headaches. The drug belongs to the triptan group of medicines.

After using eletriptan, many patients find that their headaches are completely gone. Others notice that, despite the fact that their headaches are still present, they are far less unpleasant and can resume their regular activities. This medicine is helpful for those who find other painkillers ineffective.

A migraine is a sharp pain on one side of the head that cannot go away without taking medicine. At Specialty Care Clinics, we assist with medication after confirming the symptoms of migraine. Medicine should always be taken with the advice of a doctor.

Mechanism of Action of Eletriptan

Eletriptan binds with high affinity to 5-HT1B, 5-HT1D, and 5-HT1F receptors, has a modest affinity for 5-HT1A, 5-HT1E, 5-HT2B, and 5-HT7 receptors, and little or no affinity for 5-HT2A, 5-HT2C, 5-HT3, 5-HT4, 5-HT5A and 5-HT6 receptors. Eletriptan has no significant affinity or pharmacological activity at adrenergic alpha1, alpha2, or beta; dopaminergic D1 or D2; muscarinic; or opioid receptors.

The effectiveness of 5-HT receptor agonists in the treatment of migraine has been explained by two possibilities.

According to one theory, migraine relief is associated with vasoconstriction caused by 5-HT1 receptor activation on intracranial blood vessels, including those on arteriovenous anastomoses.

According to other theory, 5-HT1 receptor activation on sensory nerve terminals in the trigeminal system inhibits pro-inflammatory neuropeptide release.
