Abstract

The present invention discloses an oral solid medicinal combination, comprises 0.5 weight percent to 3 weight percent of rasagiline and salt of rasagiline, less than 60 weight percent of pentahydric alcohol and / or hexahydric alcohol and 0.5 weight percent to 3 weight percent of organic acid. The present invention is used for curing the Parkinsonism.

Description

technical field [0001] The invention relates to a pharmaceutical composition, in particular to a novel rasagiline oral solid pharmaceutical composition for treating Parkinson's disease. Background technique [0002] Parkinson's disease is the second largest neurological chronic disease after Alzheimer's disease. The onset of Parkinson's disease is mainly due to the progressive degeneration of dopaminergic neurons in the substantia nigra-striatum system of the brain, resulting in striatum Depletion of the neurotransmitter dopamine in the major motor areas of the brain. [0003] The current drugs for the treatment of Parkinson's disease include levodopa, DA receptor agonists, MAO-B inhibitors, and COMT inhibitors. Since the 1960s, levodopa has always been the main force in the treatment of Parkinson's disease. Although levodopa has its irreplaceable advantages, it is only used as a precursor of DA to supplement DA content, which is prone to serious complications. disease. C...
