rizatriptaan

Rizatriptan is a medication used to treat migraine headaches. It belongs to a class of drugs called triptans, which work by constricting blood vessels in the brain and blocking pain pathways. Rizatriptan is typically prescribed for acute migraine attacks, meaning it is taken at the onset of symptoms. It is available in tablet form and as a orally disintegrating tablet.

The mechanism of action involves selective activation of serotonin 5-HT1B and 5-HT1D receptors. This activation leads to a reduction in the inflammation of blood vessels that is thought to contribute to migraine pain. Rizatriptan is generally effective in relieving migraine pain, as well as associated symptoms like nausea, vomiting, and sensitivity to light and sound.

Common side effects of rizatriptan can include dizziness, drowsiness, fatigue, and a tingling or warm sensation. More serious, though less common, side effects can include chest pain, shortness of breath, and allergic reactions. It is important to consult a healthcare professional before taking rizatriptan, especially if you have a history of heart disease, stroke, or uncontrolled high blood pressure. Rizatriptan is not intended for the prevention of migraines. The typical dosage for adults is 5 mg or 10 mg taken at the first sign of a migraine. It is not recommended for children under 12 years of age.
