Flunarizine is mainly employed for the prevention of migraine attacks and to lessen their severity. It's well absorbed from the gastrointestinal tract, with 85% being absorbed after oral administration. In the body, 99% of Flunarizine is transported bound to Plasma proteins. It has an elimination half-life of up to 18 days. It's important to note that there are drug interactions associated with Flunarizine​​.

This medication acts as a selective calcium-entry blocker and is used for migraine prophylaxis, particularly in patients who have severe and frequent migraine episodes and haven't responded well to more common treatments. Flunarizine also possesses calmodulin binding properties and histamine H1 blocking activity​​.

The effect of flunarizine might not be observed for several weeks, and it's advised not to stop taking the medication due to a lack of effect within the first six to eight weeks​​.

Furthermore, Flunarizine has been utilized in the medical field for over 25 years. Initially, it was introduced as a medication to enhance blood flow and is recognized as a calcium channel blocker. It has been predominantly used in the treatment of dizziness, vertigo, and the prevention of migraines. Flunarizine has proven effective in reducing the frequency of migraine attacks​​.
