Abstract

The invention discloses a probenecid slow-release tablet and a preparation method thereof. The components and parts by weight of the slow-release tablet include: 40-50 parts of probenecid, 30-35 parts of sodium bicarbonate, and 20-35 parts of blank pellet cores. 25 parts, 3-5 parts of slow-release material, 0.3-0.6 parts of plasticizer, 0.1-0.3 parts of porogen, 10-15 parts of filler, 0.5-1.0 parts of lubricant, 15-20 parts of disintegrant, package Clothing materials 2 to 5 parts. The preparation method of the sustained-release tablet comprises: preparation of raw materials, preparation of pill-containing cores, preparation of sustained-release pellets, tabletting and coating. Sodium bicarbonate is added to the formulation of the sustained-release tablet. When treating chronic gout, it only needs to be taken with a large amount of water to prevent urate from forming urinary stones in the urinary tract. Moreover, sodium bicarbonate can neutralize excessive gastric acid, and when increasing the effect of penicillins, it has the effect of invigorating the stomach and antacid. Taking it 1-2 times a day increases the patient's compliance.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a probenecid sustained-release tablet 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 ...
