Zolmitriptan: An Effective Treatment for Migraines
Zolmitriptan is a triptan medication used to treat acute migraine attacks with or without aura (visual disturbances). It works by constricting blood vessels in the brain, which become dilated during a migraine attack, and by inhibiting the release of inflammatory chemicals that contribute to migraine pain. Zolmitriptan is most effective when taken as soon as the migraine starts.
Mechanism of Action
Zolmitriptan works by stimulating serotonin receptors (5-HT1B/1D) in the brain. These receptors cause the constriction of dilated blood vessels and inhibit the release of neurotransmitters like substance P, which contribute to the inflammation and pain experienced during a migraine attack.
