Embodiment 1

[0028] Prescription: Dosage per 1000 capsules:

[0029] Bazedoxifene Acetate 2.26g

[0030] Vitamin ETPGS5.0g

[0031] Stearic acid 42.74g

[0032] Specifications: main drug content 2.26mg / grain, pill weight 50mg / grain.

[0033] Process: Grind and finely grind bazedoxifene acetate raw materials to more than 150 mesh; weigh vitamin ETPGS and stearic acid according to the prescription; heat and melt the hydrophilic matrix, add bazedoxifene acetate and mix well, then add hydrophobic Mix the base of the dropping pills to form a suspension; keep the above eutectic solution at 80-85°C and keep warm; transfer the above solution into a dropping device for dripping, control the temperature of the solution at 80-85°C, and drop it into the dimethylformamide at room temperature In the base silicone oil, remove and drain the silicone oil, and wipe off the silicone oil attached to the surface of the dripping pills with medicinal gauze.

Abstract

The invention discloses a bazedoxifene acetate sustained release preparation with excellent performance and a preparation process thereof. The preparation is a sustained release dropping pill, which comprises the following components in percentage by weight: 1-25 percent of bazedoxifene acetate, 40-70 percent of hydrophobic dropping pill matrix, and 5-40 percent of hydrophilic matrix. The sustained release dropping pill has a higher chemical stability, physical stability (low-crystal form conversion rate) and in-vivo drug-release behavior (higher bioavailability and smooth and durable plasma concentration).

Description

【Technical field】 [0001] The present invention relates to a particularly stable bazedoxifene preparation with excellent properties. More specifically, the present invention relates to a bazedoxifene acetate sustained-release preparation with excellent performance, especially stable one, and its preparation process. 【technical background】 [0002] Bazedoxifene, a new generation of SERM bazedoxifene, can competitively inhibit the binding of 1713-estradiol to estrogen receptors ERoc and ER13, has estrogen agonist activity on bones, and can improve spine and hip Therefore, it can significantly reduce the risk of vertebral fracture in postmenopausal women with osteoporosis. Its main indication is the prevention and treatment of postmenopausal bone. [0003] 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: [0004] [0005] Polymorph A of ...
