Xadago

Generic name: Safinamide
Drug class: Dopaminergic antiparkinsonism agents

Usage of Xadago

Xadago is monoamine oxidase inhibitor type B (MAO-B). This medicine works by allowing a chemical called doPamine (DOE pa meen) to work for longer periods of time in the brain. Low levels of dopamine in the brain are associated with Parkinson's disease.

Xadago is given with Levodopa and Carbidopa to treat "wearing-off" episodes (muscle stiffness, loss of muscle control) in people with Parkinson's disease.
