Abstract

The invention relates to pharmaceutical composition of piribedil / folic acid compound and purpose thereof and belongs to the technical field of pharmacy. The pharmaceutical composition contains medical dose piribedil, medical dose folic acid compound and pharmaceutical acceptable carriers, wherein the dose of the piribedil is 25-100mg, and the dose of the folic acid compound is 0.2-1.6mg. The pharmaceutical composition has the advantages that by means of synergistic effects of multiple target points, curative effects on anti-Parkinson disease are enhanced, and life quality of patients is improved; stroke risk of Parkinson patients can be effectively prevented and reduced through homocysteine (Hcy) target points; and in addition, patients can take medicine conveniently.

Description

technical field [0001] The invention relates to a pharmaceutical composition of piribedil / 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 patients in ...
