Embodiment 1

[0016] A pharmaceutical composition containing istradefylline, prepared from the following raw materials in parts by weight: istradefylline: 20 parts, puerarin: 10 parts, starch: 5 parts, low-substituted hydroxypropyl cellulose: 1 part, magnesium stearate: 2 parts, antioxidant: 2 parts, mannitol: 3 parts, micronized silica gel: 2 parts, chitin: 2 parts, sodium alginate: 2 parts, lactose: 3 parts;

[0017] Preparation process: Weigh the prescription amount of istradefylline, puerarin, starch, low-substituted hydroxypropyl cellulose, magnesium stearate, antioxidant, mannitol, micropowder silica gel, chitin, sodium alginate, lactose and mix uniform. Another appropriate amount of 60% ethanol is added to the mixed powder, mixed evenly to make a soft material, granulated through a 16-mesh sieve, and dried below 60°C. After drying, use an 18-mesh sieve to carry out granulation, sieve out the fine powder in the dry granules, mix with the sieved magnesium stearate, and then mix with t...

Abstract

The invention discloses an istradefylline containing pharmaceutical composition. The composition is prepared from, by weight, 20-50 parts of istradefylline, 10-20 parts of puerarin, 5-12 parts of starch, 1-9 parts of low-substituted hydroxypropyl cellulose, 2-6 parts of magnesium stearate, 2-8 parts of antioxidant, 3-5 parts of mannitol, 2-10 parts of superfine silica powder, 2-10 parts of chitosan, 2-8 parts of sodium alginate and 3-10 parts of lactose. A preparation process of the composition includes the steps of weighing and evenly mixing istradefylline, puerarin, starch, low-substituted hydroxypropyl cellulose, magnesium stearate, antioxidant, mannitol, superfine silica powder, chitosan, sodium alginate and lactose according to the amounts in the formula, additionally adding a proper amount of 60% ethyl alcohol to mixed powder to be evenly mixed to prepare a soft material, conducting granulating through a 16-mesh screen, conducting drying at 60 DEG C or below, conducting size stabilizing after drying is completed, evenly mixing granules with dry particles, and conducting tabletting to obtain the composition. The composition has the advantage of treating the Parkinson's disease.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a pharmaceutical composition containing istradefylline. Background technique [0002] Parkinson's disease, also known as parkinsonism, is the most common degenerative disease of the central nervous system in middle-aged and elderly people. Tremor refers to the trembling and shaking of the head and limbs, and paralysis refers to the inability of a part or all of the limbs to move voluntarily, including movement disorders, tremors, and muscle stiffness. As my country gradually enters into an aging population society, its incidence rate has been increasing year by year in recent years, and the incidence rate gradually increases with age. The age of onset generally begins at the age of 50 to 65. The incidence rate at the age of 60 is about 1‰, and at the age of 70 it reaches 3‰ to 5‰. There are currently more than 1.7 million people suffering from this disease in China. Data show ...
