One of the popular treatments for migraine is called Rizatriptan. This drug belongs to a class of medications called triptans which are not pain relievers, but rather reverses the changes in the brain that triggers migraines. By turning the changes around, Rizatriptan functions to heal the source of migraine and also lessens its symptoms.
Rizatriptan functions by energizing the serotonin in the brain. Serotonins are receptors that trigger the contraction of the blood vessels in the brain. The constricting of the blood vessels reverses the expansion. This situation is known to be one of the sources of migraines.
