Method for preparing film coating tablet for treating chronic renal failure

Abstract

The invention discloses a method for preparing a film coating tablet for treating chronic renal failure. The method comprises the following steps: proportioning various crude medicines of rhubarb, astragalus root, white mulberry root-bark, kuhseng, radix codonopsis pilosulae, white atractylodes rhizome, tuckahoe, prepared fleece flower root, white peony root, radix salviae miltiorrhizae, rhizoma ligustici wallichii, chrysanthemum, pinellia, plantain, radix bupleuri and licorice according to a conventional method, adding water, decocting, filtering, merging decoction, concentrating, drying and pulverizing to obtain medicinal extract powder; the method is characterized by also comprising the following steps: adding microcrystalline cellulose into the medicinal extract powder, mixing evenly, preparing a soft material by an ethanol water solution, granulating, drying, straightening, adding magnesium stearate, mixing evenly, tabletting to obtain a tablet agent and then coating a film coating by a film coating material; the mass ratio of the medicinal extract powder to the microcrystalline cellulose to the magnesium stearate to the film coating powder is 60-75:20-36:0.5-1.3:2-6; and the conditions of the technical parameters of the coating process for coating the film coating are as follows: the concentration of coating liquid prepared by the film coating material is 10-20wt%, the temperature of a tablet bed is 45-48 DEG C, and the liquid spraying speed of the coating liquid is 4-5ml / min.

Description

technical field [0001] The invention relates to a preparation method of a film-coated tablet for treating chronic renal failure. It belongs to the technical field of traditional Chinese medicine and natural medicine research. Background technique [0002] Kidney disease is a common disease, and about 96 to 100 people per million people develop from kidney disease to renal failure every year. Uremia is the end stage of chronic renal failure (CRF). In addition to water and electrolyte metabolism disorders and acid In addition to the imbalance of alkali balance, the accumulation of a large number of metabolites in the human body causes symptoms of poisoning in the digestive tract, heart, lungs, nerves, skin, muscles, blood and other systemic systems, which is one of the most complicated and difficult problems in clinical nephrology. , which belongs to the category of insufficiency, closure, drug addiction, and consumptive fatigue in traditional Chinese medicine. A large numbe...
