Migrium 10 mg Tablet contains Flunarizine, a calcium channel blocker used primarily for the prevention of migraines. It works by reducing the influx of calcium into brain cells, helping to stabilize nerve activity that can trigger migraines. Apart from migraine prevention, it is also used to treat vestibular disorders such as vertigo, and sometimes as an adjunct therapy in epilepsy or other conditions related to blood flow or nerve sensitivity. It is taken orally and typically administered once daily, usually at night, due to its sedative effects.
