Flunarizine, sold under the brand name Sibelium among others, is a drug classified as a calcium antagonist which is used for various indications. It is not available by prescription in the United States or Japan. The drug was discovered at Janssen Pharmaceutica (R14950) in 1968.
==Medical uses== Flunarizine is effective in the prophylaxis of migraine, occlusive peripheral vascular disease, vertigo of central and peripheral origin, and as an add-on in the treatment of epilepsy where its effect is weak and not recommended. It has been shown to significantly reduce headache frequency and severity in both adults and children.
