Stugeron Forte (Cinnarizine) is a travel sickness medicine that is widely used to prevent vomiting, vertigo and nausea caused by travelling in a boat or car. More recently it has seen use as a memory and cognitive function enhancer (nootropic). It belongs to a class of drugs called antihistamines, and it helps to block the muscarinic and histamine receptors in the part of the brain that controls vomiting, thereby preventing motion sickness symptoms.
