What are 5-HT agonist?
Serotonin 5-HT-receptor agonists are drugs used for treating moderately severe to severe migraine headaches. Migraine occurs when a specific nerve in the blood vessels sends pain signals to the brain.
What are serotonin agonists used for?
Endogenous compounds and drugs that bind to and activate SEROTONIN RECEPTORS. Many serotonin receptor agonists are used as ANTIDEPRESSANTS; ANXIOLYTICS; and in the treatment of MIGRAINE DISORDERS. A triptan used for the treatment of migraines.
What are 5-HT migraine agents?
5-HT1-receptor agonists, commonly known as the ‘triptans’, are the mainstay for acute treatment of migraine headaches. The clinical introduction of sumatriptan in 1992, followed by several other drugs such as zolmitriptan, naratriptan and rizatriptan, has led to major progress in migraine research.
Is an SSRI a serotonin agonist?
SSRI/5HT-1A partial agonists increase the levels of serotonin and also enhance the activity of a specific type of serotonin receptors known as 5HT-1A receptors. Serotonin is an important natural chemical (neurotransmitter) released by nerve cells (neurons) in the brain to transmit nerve signals.
Which serotonin receptor antagonist is used in migraine?
Zolmitriptan (Zomig, Zomig-ZMT) A selective agonist for serotonin 5-HT1B/1D receptors in cranial arteries, zolmitriptan suppresses the inflammation associated with migraine headaches. It has an efficacy of 62% at 2 hours and of 75-78% within 4 hours.
Which of the following drugs is an example of a selective 5 HT receptor agonist?
Rizatriptan is a selective agonist for serotonin 5-HT1 receptors in cranial arteries and suppresses the inflammation associated with migraine headaches.
