Embodiment 1

[0028] Embodiment 1: the preparation of pharmaceutical composition 1, its formulation prescription (prescription quantity 100) is:

[0029]

[0030]

[0031] Preparation method: Take the prescribed amount of purified water, boil and cool to 80°C. Weigh 50 g sodium sulfobutylbeta cyclodextrin (substitution degree 6.2-6.9, average substitution degree 6.4, molecular weight 2145.2 g / mol), 90 g sodium chloride, add to 8 L 80 ° C purified water, stir to dissolve completely. Weigh 2.5 g of butylphthalide, add it to the sodium sulfobutylbeta cyclodextrin solution, stir in an oil bath at 80°C for 90 minutes to dissolve completely. Allow to cool to room temperature, add 0.2M hydrochloric acid solution to adjust the pH value to 4.5, and add purified water to 10L. Filter through a 0.45 μm filter membrane with a circulating water-type multi-purpose vacuum pump. Fill the prepared solution in 100ml / bottle. After filling, it was sterilized at 121° C. for 15 minutes at high temperatur...

Abstract

The invention discloses application of a butylphthalide composition in preparation of a medicine for preventing or treating nephropathy, and relates to the field of chemistry and medicine. According to the application of the composition in preparation of the medicine for preventing or treating the nephropathy, the composition comprises butylphthalide with an effective dose or pharmaceutically acceptable salt of butylphthalide, and further comprises a pharmaceutically acceptable carrier sulfobutyl beta-cyclodextrin sodium. The composition disclosed by the invention has a kidney protection effect on both acute kidney injury and chronic kidney injury. The composition not only can be used for treating acute or chronic renal insufficiency nephropathy, but also can be used for treating cerebral apoplexy complicated nephropathy.

Description

technical field [0001] The present invention relates to the field of chemistry and medicine, specifically, the present invention relates to the new application of the composition containing butylphthalide or its salt, more specifically relates to the preparation of the composition containing butylphthalide or its salt in the medicine for preventing or treating nephropathy Applications. Background technique [0002] The incidence rate of chronic kidney disease (CKD) in my country is about 10.8%. Chronic kidney disease has become a public health problem. Studies have shown (Wang Hailong et al. Meta-analysis of the relationship between chronic kidney disease and stroke [J]. Chinese General Medicine, 2012, v.15; No.321(05):485-489): Chronic kidney disease can increase the risk of stroke is a risk factor for stroke. The probability of stroke in CKD patients is 1.31 times that of normal people; in addition, the probability of ischemic stroke in CKD patients is higher than that o...
