Effects of this medicine
This medicine is a combination preparation of levodopa and carbidopa. Levodopa is taken up into the brain and changes into dopamine to supplement insufficient dopamine, and consequently improves Parkinson's disease. Carbidopa enhances the transfer of levodopa into the brain. The medicine takes effect on akinesia, muscle rigidity and tremor associated with Parkinson's disease and parkinsonian syndrome, and improves body movements in daily life. It also improves other accompanying symptoms.
It is usually used for the treatment of Parkinson's disease and parkinsonian syndrome.
