General Info:

Cinnarizine is an antihistamine drug. It is usually used to control vomiting as an effect of motion sickness. It is widely distributed worldwide by Janssen Pharmaceutica since 1955 under the trade name Stugeron.

Cinnarizine works by creating interference on the transmission of signals between the vestibular apparatus of your inner ear and the vomiting center of your hypothalamus. Since the signal transmission is disturbed, your brain will be slightly confused whether you are actually moving or not. Thus, it prevents vomiting to happen. Vomiting induced by motion sickness is signaled by the brain to prevent any more motion to occur so it can adapt to the current signal. Aside from its antihistaminic properties, Cinnarizine also has nootropic powers that boost the supply of oxygen in the brain.
