Contain the active ingredient: Eletriptan, which is a type of medicine called a serotonin (or 5HT) agonist. This type of medicine is also commonly known as a 'triptan'. It is a painkiller specifically used to relieve migraine attacks.
Although the cause of migraine attacks is not fully understood, it is thought that widening of blood vessels in the brain causes the throbbing pain of migraine headaches. Eletriptan relieves this pain by causing the blood vessels in the brain to narrow.
Eletriptan works by stimulating receptors called serotonin (or 5HT) receptors that are found in the brain. A natural substance called serotonin normally acts on these receptors, causing blood vessels in the brain to narrow. Eletriptan mimics this action of serotonin by directly stimulating the serotonin receptors in the brain. This narrows the blood vessels and so relieves the pain of migraine headaches.
The dose of eletriptan should be taken as early as possible after the migraine headache has started, though it is also effective if taken at a later stage during the migraine attack. It should not be taken during the aura or warning phase of a migraine, as it will not prevent the headache.
