Abstract

The invention relates to a carbidopa / levodopa / folic acid compound medicine composition and the use thereof, and belongs to the technical field of pharmacy. The medicine combination comprises the carbidopa with an officinal dose, the levodopa with an officinal dose, the folic acid compounds with an officinal dose, and a carrier which can be accepted in pharmacy. The dose of the carbidopa is 10-60 mg, the dose of the levodopa is 100-300 mg, and the dose of the folic acid compounds is 0.2-1.6 mg. The medicine combination has the advantages that through synergistic effect of multiple target points, curative effect on the Parkinson's disease is improved, life quality of a patient is improved, through a homocysteine (Hcy) target point, cerebral apoplexy of the patient with the Parkinson's disease can be effectively prevented, occurring risk of the cerebral apoplexy can be effectively lowered, and in addition, the patient can conveniently take medicine.

Description

technical field [0001] The invention relates to a pharmaceutical composition of carbidopa / levodopa / folate compound and its application, belonging to the technical field of pharmacy. Background technique [0002] Parkinson's disease (PD) is a chronic progressive disease of extrapyramidal dysfunction in the central nervous system. The main pathological manifestations of PD are the degeneration of dopamine (DA) neurons in the substantia nigra, and the decrease of the content of central neurotransmitter DA, and the degree of depletion of DA is consistent with the severity of PD; at the same time, it can also be accompanied by acetylcholine (Ach), 5- Abnormality and imbalance of various neurotransmitters such as serotonin (5-HT), norepinephrine (NE), γ-aminobutyric acid, and neuropeptides, resulting in a series of clinical symptoms, such as muscle tremors, stiffness, and postural disturbances , movement difficulties, etc. According to reports, there are about 1.5 million PD pat...
