Example Embodiment

[0082] Example 1

[0083]

[0084] Preparation:

[0085] The hypromellose was configured as a 5% aqueous solution, and anhydrous citric acid was added and stirred until dissolved. Put levodopa, benserazide hydrochloride, and starch into a PMA-25 high-speed stirring granulator (GEA Company, Germany) after crushing and sieving, start mixing, add slurry soft materials, and pass through a YK-60 oscillating granulator (Shanghai) Tianxiang Jiantai Pharmaceutical Machinery Co., Ltd.) sieves the wet granules, then the wet granules are dried on the FL-5 type fluidized granulator (Shanghai Huafa Pharmaceutical Machinery Complete Set Development Company), granulated, and magnesium stearate is added. After mixing by a V-type high-efficiency mixer (Shanghai Tianhe Pharmaceutical Machinery Co., Ltd.), GKF-120 capsule filling machine (Bosch Packaging Technology (Hangzhou) Co., Ltd.) fills the capsules.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a pharmaceutical composition containing a dopamine prodrug for treating Parkinson's disease and symptomatic Parkinson's syndrome and a preparation method thereof. Background technique [0002] Parkinson's disease is a degenerative disease of the central nervous system that seriously endangers the health of middle-aged and elderly people. The cause of its onset is the lack of dopamine in the basal ganglia of patients. At present, the drugs for the treatment of Parkinson's disease are roughly divided into five categories: dopamine prodrugs, dopamine receptor agonists, levodopa potentiators, cholinergic receptor blockers, and dopamine release-stimulating drugs. Dopamine prodrugs (levodopa-like drugs, such as levodopa, etid-levodopa) have been the most basic drugs for the treatment of Parkinson's disease since the 1960s. Dopamine cannot enter the central nervous system through the ...
