HOW DO SEROTONIN 5-HT-RECEPTOR AGONISTS WORK?
Migraine occurs when a specific nerve in the blood vessels sends pain signals to the brain. As a result, inflammatory substances get released into the nerves and blood vessels of the head, causing dilation and inflammation of these blood vessels.
There are two types of antimigraine agents:
Abortive agents: These agents abort an established migraine attack.
Preventive antimigraine agents: These agents are given prophylactically to reduce the number of migraine attacks.
Serotonin 5-HT-receptor agonists work as abortive agents. Abortive agents constrict the blood vessels and prevent inflammation by stimulating 5-HT-receptors in the brain. 5-HT-receptor agonists bind to the 5-HT-receptors in the brain and inhibit the release of serotonin to reduce pain, nausea, and other symptoms of migraine.
HOW ARE SEROTONIN 5-HT-RECEPTOR AGONISTS USED?
