[0033] Sodium lauryl sulfate and purified water are prepared into a solution with a concentration of about 10% for later use.

[0034] The bazedoxifene acetate, filler, binder, disintegrant, and antioxidant are weighed and mixed together, and after mixing, a wetting agent solution is added to carry out wet granulation or fluidized bed granulation process. After granulation, dry at 50-60°C to control the water content to 1-4%, pass through a 40-mesh sieve for granulation. Add the rest of the materials, mix them, compress into tablets and coat them.

Abstract

The invention discloses a bazedoxifene (Viviant) acetate composition and a bazedoxifene acetate film-coated tablet preparation method, and relates to the technical field of medicines. The bazedoxifene acetate composition comprises the following components by weight of 20-26 parts of bazedoxifene acetate, 250-350 parts of a filling agent, 30-50 parts of an adhesive, 8-15 parts of a disintegrating agent, 3-6 parts of an antioxidant, 2-6 parts of a flow aid, 0.1-0.5 part of a lubricant, 1-3 parts of a wetting agent, and a proper amount of a purified water solvent, wherein bazedoxifene acetate is a BCS II type medicine, and the particle size D90 is 30 microns; the antioxidant is vitamin C; and the filling agent is composed of lactose and microcrystalline cellulose, and the ratio of the lactose to the microcrystalline cellulose is 1: 2-2: 1 according to the weight fraction. The fluidized bed granulation technology adopting the process for preparation is simple in process, lower in cost and easy for industrial production.

Description

technical field [0001] The invention relates to the technical field of medicine preparation, in particular to a bazedoxifene acetate composition and a method for preparing bazedoxifene acetate film-coated tablets. Background technique [0002] The chemical name of bazedoxifene acetate is (1-[4-(2-azepan-1-yl-ethoxy)-benzyl]-2-(4-hydroxy-phenyl)-3-methyl base-1H-indole-5-ol acetic acid), has the chemical structure shown below: [0003] [0004] It is a new type of third-generation selective estrogen receptor modulators (selective estro-genreceptor modulators, SERMs), which can competitively inhibit the binding of 17β-estradiol to estrogen receptors ERα and ERβ, thereby Activates estrogen receptors in skeletal tissue, thereby increasing bone density in the spine and hip. The drug is mainly used for the prevention and treatment of osteoporosis in postmenopausal women. It has almost no stimulation to the breast and uterus, and will not cause hyperplasia of the breast and en...
