Rizatriptan is in the triptan class and is believed to work by activating the 5-HT 1 receptor. [3] Rizatriptan was patented in 1991 and came into medical use in 1998. [5] [6] It is available as a generic medication. [4] In 2022, it was the 190th most commonly prescribed medication in the United States, with more than 2 million prescriptions. [7 ...
Rizatriptan has central trigeminal antinociceptive activity. Other possibilities of triptans in antimigraine effects are modulation of nitric oxide dependent signal transduction pathways , nitric oxide scavenging in the brain, and sodium dependent cell metabolic activity.

Gepants have been suggested to have less pain relief at 2 hours compared to triptans.

In addition to being 5-HT 1B agonists, triptans (i.e. sumatriptan, almotriptan, zolmitriptan, naratriptan, eletriptan, frovatriptan and rizatriptan) are also agonists at the 5-HT 1D receptor, which contributes to their antimigraine effect caused by vasoconstriction of blood vessels in the brain. The same is true for ergotamine.
