Levodopa tablets

Function and Efficacy

This product is a dopamine-like anti-Parkinson's disease drug. Levodopa is a precursor substance for synthesizing dopamine in the body. It has no pharmacological activity itself. It enters the central nervous system through the blood-brain barrier and is converted into dopamine by dopa decarboxylase to exert its pharmacological effects and improve the symptoms of Parkinson's disease. Since this product can increase neurotransmitters such as dopamine and norepinephrine in the brain, it can also improve the brain's tolerance to ammonia, and is used to treat hepatic coma, improve central nervous system function, make patients sober, and improve symptoms.
