Flurizin 5

Generic

Flunarizine

 

Indication

Flurizin® is indicated in:

– Prophylaxis of classic (with aura) or common (without aura) migraine.

– Symptomatic treatment of vestibular vertigo (functional disorder of the vestibular system).

Pharmacology

Flunarizine is a selective calcium antagonist. It prevents cellular calcium overload by reducing excessive transmembrane calcium in­uxes. Flunarizine does not interfere with normal cellular calcium homeostasis. Flunarizine also has antihistaminic properties. The e‑ects of Flunarizine in the prophylaxis of migraine are most pronounced with regards to the reduction of the frequency of attacks.

 

Dose and Administration

Migraine Prophylaxis

Starting Dose: 10 mg at night in patients less than 65 years of age and 5 mg daily in patients older than 65 years. If, after 2 months of this initial treatment, no signicant improvement is observed, the patient should be considered a non-responder and administration should be discontinued.

Maintenance Treatment: If a patient is responding satisfactorily and if a maintenance treatment is needed, the dose should be decreased to 5 days treatment at the same daily dose with two successive medicine free days every week. Even if the prophylactic maintenance treatment is successful and well tolerated, it should be interrupted after 6 months and it should be re-initiated only if the patient relapses.

Vertigo: The same dosage should be used as for migraine, but the starting treatment should not be given longer than needed for symptom control, which generally takes less than two months.
