Abstract

The invention relates to a cefixime liposome, a preparation method thereof and a dispersible tablet containing the cefixime liposome. The dispersible tablet comprises the cefixime liposome and a pharmaceutically acceptable carrier, wherein the cefixime liposome comprises the following components in parts by weight: 1 part of cefixime, 1.25-5 parts of hydrogenated soybean lecithin, 1.25-5 parts of hydrogenated egg yolk lecithin, 1.25-10 parts of cholesterol and 0.2-3.5 parts of polysorbate 80. The dispersible tablet not only conforms to the requirements of a Chinese pharmacopoeia, but also has the advantages of more stable storage under normal temperature and remarkable improvement of bioavailability compared with the ordinary cefixime medicament composition, and can take effect more rapidly.

Description

Technical field [0001] The invention relates to a cefixime liposome, a preparation method thereof and a dispersible tablet containing it. The cefixime dispersible tablet has the characteristics of being more stable when stored at normal temperature and exerting a greater efficacy than ordinary cefixime pharmaceutical compositions. The advantages of rapid and significantly improved bioavailability belong to the field of medical technology. Background technique [0002] Acute pelvic inflammatory disease refers to the acute inflammation of female pelvic reproductive organs and surrounding connective tissue and pelvic peritoneum, including metritis, fallopian tube oophoritis, pelvic connective tissue inflammation and pelvic peritonitis. It can occur in one or several places at the same time. It is a common disease in women. One of the common diseases. The development of acute pelvic inflammatory disease can cause diffuse peritonitis, sepsis, septic shock, and severe cases can b...
