Abstract

The invention discloses a stable oteracil potassium suspension which comprises the following raw materials in parts by weight: 1-3 parts of oteracil potassium, 0.2-1 part of carboxymethylcellulose and50-60 parts of deionized water. Further, the invention provides a preparation method of the stable oteracil potassium suspension. The preparation method comprises the following steps: weighing oteracil potassium in parts by weight, adding the oteracil potassium into deionized water in one half of the weight parts, and uniformly stirring to obtain oteracil potassium dispersion; weighing carboxymethylcellulose in parts by weight, adding the carboxymethylcellulose into deionized water accounting for 1/4 of the weight parts, and uniformly stirring to obtain a carboxymethylcellulose solution; adding the prepared carboxymethylcellulose solution into the prepared oteracil potassium dispersion, uniformly stirring, adding the rest deionized water accounting for 1/4 of the weight parts, and whirling, so as to obtain the stable oteracil potassium suspension. The oteracil potassium can be uniformly and stably dispersed into the aqueous solution, so that the stable oteracil potassium suspension with excellent dispersion stability and storage simplicity is prepared.

Description

technical field [0001] The invention relates to a suspension. More specifically, the present invention relates to a stable suspension of potassium oxonate, which belongs to the field of biotechnology. Background technique [0002] Potassium oxonate, also known as oteracil potassium, its molecular formula is C 4 h 2 KN 3 o 4 , with a molecular weight of 195.17, is a white crystalline powder, hardly soluble in water, and its molecular structure is as follows: [0003] [0004] Potassium oxonate, as a urate oxidase inhibitor, is mainly used in biological experiments to construct models of hyperuricemia and gout, so as to screen urate-lowering and gout drugs. It is very difficult to inject the potassium oxinate solution into mice, soak the cells, etc. Therefore, how to prepare a stable suspension of potassium oxonate is of great significance to the application of potassium oxonate in medical and pharmaceutical experiments, drug research and development, and the like. ...
