Embodiment 3

[0105] Streptococcus (STZ) is a kind of widely used medicine that causes rat diabetes model, male Wistar rat body weight 180-220g, single intraperitoneal injection is dissolved in the STZ of pH=4.5 sodium citrate (27.5mg / mL ), calculated as 55mg / kg based on body weight. The control group was injected with the same volume of solvent sodium proxylate (0.2mL / 100g). Three days after the injection, blood was taken from the tail vein to measure blood sugar. Rats with blood glucose greater than or equal to 16.7mmol / L were selected as experimental rats. The screened rats were divided into groups and oral administration was started. Urine was collected for 12 hours (21:00-9:00) every two weeks from the injection of STZ in rat metabolic cages and the urine protein content was determined. After fasting at 21:00 the night before for days 0, 4, 8, and 12, blood was taken from the tail vein at 9:00 the next morning to measure the blood sugar concentration. After the rats in each group we...

Abstract

The invention relates to the field of compound medical preparations, and especially relates to applications of a compound preparation of diacerein and berberine in the medicine field. The invention discloses an oral pharmaceutical composition, which is composed of pharmaceutical active components and pharmaceutical auxiliary materials; wherein the pharmaceutical active components are composed of berberine/pharmaceutically-acceptable salts of berberine and diacerein/pharmaceutically-acceptable salts of diacerein, and the pharmaceutically-acceptable salts can be hydrochloride or sulfate. The pharmaceutical composition can be made into common tablets, dual-layer tablets, enteric coated tablets, capsules, particles, and powder. The pharmaceutical composition can reduce the blood sugar and blood fat, and prevent/treat diabetic complication, especially diabetic nephropathy.

Description

technical field [0001] The invention relates to the field of compound pharmaceutical preparations, in particular to the application of a compound preparation of berberine and diacetylrhein in the field of medicine. Background technique [0002] Berberine, also known as berberine, is an alkaloid extracted from plants such as Cortex Phellodendron, Coptidis Rhizoma, and Three Needles, and can also be synthesized artificially. At first, berberine tablets were mainly used for intestinal infections such as gastroenteritis and bacterial venereal diseases caused by sensitive pathogenic bacteria. The pharmacodynamics of the drug is that it has a broad antibacterial spectrum, and it has inhibitory effects on a variety of Gram-positive and Gram-negative bacteria in vitro, including hemolytic streptococcus, Staphylococcus aureus, Vibrio cholerae, meningococcus, typhoid Bacillus, diphtheria, etc. have a strong inhibitory effect. The mechanism of action is that microcarpine can reduce t...
