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.

This product is a non-narcotic analgesic with analgesic, sedative, hypnotic and tranquilizing effects. Its analgesic effect is stronger than that of general antipyretic analgesics. The analgesic effect appears 10 minutes after taking the medicine and can last for 2-5 hours. It has a good analgesic effect on dull pain caused by the gastrointestinal system, but has a poor effect on severe pain such as trauma. It is also effective for menstrual pain, and is more suitable for insomnia, especially insomnia caused by pain, and has no sequelae after waking up.
