Ronopar^®

Ronopar® contains two active ingredients: Levodopa and Benserazide.

Patients with Parkinson’s disease have insufficient dopamine levels in certain areas of the brain, resulting in symptoms such as slowness of movement, muscle rigidity, and tremor. Levodopa is converted to dopamine (the active form) within the brain and helps improve the symptoms of Parkinson’s disease.

Benserazide inhibits the conversion of Levodopa to dopamine before it reaches the brain, allowing a greater amount of Levodopa to enter the central nervous system and thereby enhancing its therapeutic effect.
