Cinnarizine is an antihistamine and calcium channel blocker of the diphenylmethylpiperazine group. It is prescribed for nausea and vomiting due to motion sickness or other sources such as chemotherapy, vertigo, or Ménière's disease. Cinnarizine is one of the leading causes of drug-induced parkinsonism.

Cinnarizine was first synthesized as R1575 by Janssen Pharmaceutica in 1955. The nonproprietary name is derived from the cinnamyl substituent on the free nitrogen atom of the benzhydrylpiperazine core, combined with the generic ending "-rizine" for "antihistaminics/cerebral (or peripheral) vasodilators". It is not available in the United States or Canada. It has also been cited as one of the most used drugs for seasickness within the British Royal Navy.
