Abstract

The invention provides a pharmaceutical composition for preventing or treating gouty arthritis, which is prepared by extracting 10% v / v-90% v / v ethanol aqueous solution from Qinpi, Smilax smilax and Achyranthes bidentata. The invention also provides the preparation method and application of the pharmaceutical composition, as well as the pharmaceutical preparation containing the pharmaceutical composition and the preparation method thereof. The pharmaceutical composition of the invention has good anti-inflammatory and antibacterial effects, and can effectively prevent or treat gouty arthritis. Although the pharmaceutical composition of the present invention has few raw materials and medicinal flavors, the combined use of the three has better detoxification and synergistic effects. The source of raw materials of the pharmaceutical composition of the invention is easy to obtain, easy to be industrialized, can be made into various dosage forms according to needs, and provides more convenient, more effective and more controllable modern Chinese medicine for clinical practice.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine, and relates to a pharmaceutical composition for preventing or treating gouty arthritis, a preparation method and application thereof, and a pharmaceutical preparation containing the pharmaceutical composition and a preparation method thereof. Background technique [0002] Gout is a disease in which urate is deposited in tissues due to the disorder of purine metabolism, which leads to increased blood uric acid level and / or decreased excretion of uric acid. Urate deposition in joints can lead to acute and chronic arthritis, which is called gouty arthritis . [0003] Acute gouty arthritis is an inflammatory response caused by urate sodium salt microcrystals. Its clinical symptoms are joint swelling, unbearable pain, and recurrent attacks. The solubility of uric acid in body fluids is low. At pH=7.4, the highest solubility of uric acid is 380 μmol / L. When the solubility is exceeded, a sup...
