Abstract

The invention discloses a probenecid slow release capsule and a preparation method. The slow release capsule comprises the following ingredients in parts by weight: 5-8 parts of cefalexin, 5-8 parts of probenecid and 20-25 parts of medicinal auxiliary material. The preparation method of the slow release capsule comprises the steps of material preparation, preparation of cefalexin medicated pellets, preparation of probenecid medicated pellets, preparation of slow release pellets, and capsule loading. Cefalexin and probenecid are organically combined into the slow release capsule; the usage of active ingredients is saved; the usage of the medicinal auxiliary material is reduced to the greatest extent; the influence of reduction of blood concentration of cefalexin on the curative effect due to forget of taking probenecid is avoided; and the patient compliance is good. A preparation technology has high stability, the production efficiency is improved, and the whole technology does not adopt a toxic organic reagent and is green, environment-friendly and good in stability.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a probenecid slow-release capsule and a preparation method thereof. Background technique [0002] Hyperuricemia (HUA) refers to hyperuricemia when the blood uric acid level on an empty stomach exceeds 420 μmol / L for men and 360 μmol / L for women on two different days in a normal purine diet. Uric acid is the terminal metabolite of human purine compounds. Disorders of purine metabolism lead to hyperuricemia. According to reports on the prevalence of hyperuricemia in various places in recent years, there are currently about 120 million hyperuricemia patients in my country, accounting for about 10% of the total population. trend. [0003] Probenecid is a white crystalline powder, odorless, slightly bitter taste, soluble in acetone, slightly soluble in ethanol or chloroform, almost insoluble in water, soluble in dilute sodium hydroxide solution, almost insoluble in dilu...
