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 competitive angiotensin converting enzyme inhibitor, which prevents angiotensin I from converting into angiotensin II, thereby reducing peripheral vascular resistance and reducing water and sodium retention by inhibiting aldosterone secretion. This product can also dilate peripheral blood vessels by interfering with the degradation of bradykinin. For patients with heart failure, this product can also reduce pulmonary capillary wedge pressure and pulmonary vascular resistance, increase cardiac output and exercise tolerance time.

Antiviral drug. It has an inhibitory effect on herpes simplex virus, varicella zoster virus, cytomegalovirus, etc. in vitro. It is phosphorylated into activated acyclovir triphosphate, which inhibits viral replication in two ways: ① interfering with viral DNA polymerase; ② binding to the growing DNA chain to cause the extension of the DNA chain to be interrupted. It has a special affinity for viruses, but has low toxicity to mammalian host cells.
