Problems solved by technology

[0003] Berberine hydrochloride tablets currently on the market have a single specification, mainly 0.1g. For example, the treatment of diabetes and its complications has great limitations. very good blood levels
If simply changing the specifications of berberine hydrochloride, its dissolution rate and bioavailability cannot reach the Pharmacopoeia standard

Abstract

The invention discloses a preparation method of a berberine hydrochloride tablet, and the preparation method is applied to the field of pharmaceutical preparation. The berberine hydrochloride tablet consists of a tablet core and a coating material, wherein the tablet core consists of berberine hydrochloride and auxiliary materials, each tablet contains 300mg of the berberine hydrochloride, and the auxiliary materials contains one or a plurality of a filling agent, a disintegrating agent, a lubricant, a surfactant and a wetting agent; a coating layer consists of the coating material and water; the coating layer further contains a plasticizer or an antiadherent, wherein the filling agent contains one or a random composition of starch, lactose, pregelatinized starch and microcrystalline cellulose; the disintegrating agent contains one or a random composition of crosslinking sodium carboxymethyl cellulose, polyvinylpolypyrrolidone, sodium carboxymethyl starch, hydroxypropyl starch and low-substitution hydroxyl propyl cellulose; and the lubricant contains one or a random composition of aerosol, talc powder and magnesium stearate. The method is suitable for the large-scale and long-time production of production departments, and has the advantages of stable technology, no dependence on tablet machines, good particle liquidity and formation, controllable tablet weight difference, stable quality, high tablet core hardness, difficulty in wearing and coating suitability.

Description

technical field [0001] The invention relates to a berberine hydrochloride tablet in the field of pharmaceutical preparations and a preparation method thereof. Background technique [0002] Berberine hydrochloride, also known as berberine, is an alkaloid extracted from plants such as Cortex Phellodendron, Coptidis Rhizoma, and Three Needles, and can also be synthesized artificially. Initially, berberine hydrochloride tablets were mainly used for intestinal infections such as gastroenteritis and bacillary dysentery caused by sensitive pathogenic bacteria. The pharmacodynamics of the drug is that it has a broad antibacterial spectrum, and it has inhibitory effects on a variety of Gram-positive and Gram-negative bacteria in vitro, including hemolytic streptococcus, Staphylococcus aureus, Vibrio cholerae, meningococcus, typhoid Bacillus, diphtheria, etc. have a strong inhibitory effect. The mechanism of action is that berberine hydrochloride can reduce the number of military ca...
