[0032] The preparation process description of bazedoxifene acetate tablet:
[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. Comparative example: in vitro release test of prepared samples
