Abstract

The invention belongs to the field of medicinal preparations, and relates to a lasofoxifene tartrate orally disintegrating tablet for treating postmenopausal osteoporosis and a preparation method thereof. Proper medical auxiliaries are selected according to physicochemical properties of lasofoxifene tartrate, and the orally disintegrating tablet comprises a filling agent, a disintegrating agent, a flavoring agent, a lubricant, a glidant and the like. The medicine can be prepared by granulating and tabletting by a wet method, directly tabletting, or granulating and tabletting by a dry method. The invention aims to provide the lasofoxifene tartrate orally disintegrating tablet with simple preparation process, convenience in administration, quick response to indications, exact curative effect and high bioavailability.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and relates to a medicine convenient for taking and a preparation method thereof, in particular to an orally disintegrating tablet of lasofoxifene tartrate for preventing and treating postmenopausal osteoporosis and a preparation method thereof. Background technique [0002] Osteoporosis is a worldwide health problem that attracts more and more attention. Osteoporosis refers to the reduction of bone mass per unit volume and the change of normal bone structure, which leads to the reduction of bone toughness and stiffness. Clinically, low back pain, kyphosis, and fractures can be induced by minor trauma. Metabolic bone disease threatening the health of the elderly. At present, my country has entered an aging society, and the prevention and treatment of geriatric diseases, especially osteoporosis, has become an important research topic. Osteoporosis occurs more rapidly in women and progr...
