1. What Imigran Novum is and what it is used for
Imigran Novum containing sumatriptan belonging to a group of drugs called triptans ( also known as 5-HT 1 – receptor agonists).
Imigran Novum is used for treating migraines.
The migraine symptoms are probably caused by a temporary dilation of the blood vessels in the head. Imigran Novum is considered to reduce the dilation of these blood vessels. This contributes to the disappearance of the headache as well as other migraine symptoms such as nausea, vomiting, and sensitivity to light and sound.
