preparation example Construction

[0045] Some embodiments of the present invention provide a method for preparing a controlled-release tablet containing policosanol as described above, comprising the following steps:

[0046] mixing policosanol, surfactant, carrier material, binder and solvent to obtain a drug-containing solution; the drug-containing solution, filler and lubricant are wet granulated to obtain drug-containing layer particles;

[0047] Provide booster layer particles and coating material solutions respectively;

[0048] Compressing the drug-containing layer granules and the booster layer granules to obtain a double-layer tablet core;

[0049] The double-layer tablet core is coated with the coating material solution, and then punched to obtain a controlled-release tablet containing policosanol.

[0050] Wherein, the specific types and dosages of the active ingredients of the drug and each auxiliary material are as described in the previous prescription. In a specific embodiment of the present i...

Abstract

The invention relates to the technical field of policosanol preparations, and provides a policosanol-containing solid dispersion, the policosanol-containing solid dispersion comprises policosanol, a surfactant and a carrier, and the surfactant is a nonionic surfactant used for auxiliary dispersion; the particle size of the solid dispersion is not greater than 5 microns. The invention provides a controlled-release tablet containing policosanol and a preparation method of the controlled-release tablet. The tablet comprises a double-layer tablet core and a controlled-release film layer wrapping the double-layer tablet core; the double-layer tablet core is composed of a drug-containing layer and a boosting layer; the drug-containing layer comprises policosanol, a surfactant, a filler, a carrier, an adhesive and a lubricant; the content of policosanol in each controlled-release tablet is more than or equal to 5mg. The particle size of policosanol in the drug can be greatly reduced, the dispersity and solubility of policosanol can be improved, the release rate of policosanol can be controlled, the release time and the medicine taking interval can be prolonged, and then the bioavailability of policosanol in a human body and the medicine taking compliance of policosanol can be improved.

Description

technical field [0001] The invention relates to the technical field of policosanol preparations, in particular to a solid dispersion containing policosanol, a controlled-release tablet and a preparation method thereof. Background technique [0002] Policosanol is a mixture of eight higher fatty alcohols, including octacosanol, which is extracted from cane wax. Through animal experiments, it was found that policosanol can reduce the serum cholesterol and low-density lipoprotein (LDL-C) levels of normal and endogenous hypercholesterolemic animals. Studies in various animal models have shown that policosanol can lower cholesterol in the liver, adipose tissue, and heart. The active ingredient drug has almost no acute toxicity when taken orally, and no genotoxicity, reproductive toxicity and carcinogenicity have been seen. [0003] Policosanol tablets were first developed by Cuba Dalma Laboratories Co., Ltd., and were approved by the Cuban Food and Drug Administration in 1991 t...
