Abstract

A slowly releasing conjugated oestrogen composition for preventing and treating femal climacteric syndrome, osteoporosis and coronary heart disease and male senile dementia is composed of slow-releasing layer and core containing conjugated oestrogen and progestogen.

Description

technical field [0001] The present invention relates to a pharmaceutical composition containing conjugated estrogen and a preparation method thereof. After oral administration, the sustained release composition of conjugated estrogen drug releases medicine regularly and slowly to treat and prevent menopausal syndrome occurring during female physiological or artificial menopause , prevention and treatment of osteoporosis and coronary heart disease, prevention and treatment of male Alzheimer's disease. Background technique [0002] Since 1930, it was suggested that estrogen be used for the prevention and treatment of menopausal syndrome, thus establishing the basis of estrogen replacement therapy. In the 1950s, the United States first started the commercial production of estrogen replacement therapy products. At present, it is believed that the lack of estrogen after menopause should be adjusted, supplemented and treated like other endocrine gland dy...
