FlunarizineAbout FlunarizineCalcium channel blocker and H1 blocker, Diphenyl Piperazine derivative, Antivertigo,Anti migraine, vasodilator, anticonvulsant.Mechanism of Action of FlunarizineFlunarizine is the diflourinated derivative of Cinnarizine. Flunarizine has H1 antihistaminic, sedative and calcium channel blocking actions. It is a cerebro selective calcium ion (Ca +2) channel blocker.

It inhibits the vasospasm induced by mediators such as serotonin and prostaglandins.
Antihistamines are the mainstay of the treatment of vertigo. Flunarizine suppresses end organ receptors or inhibit central cholinergic pathway in vestibular nuclei and produces antivertigo action
