Abstract

The invention provides a powdered oseltamivir phosphate medicinal composition, which comprises a therapeutic or prevention effective amount of oseltamivir phosphate, sodium glutamate and any one or more pharmaceutically acceptable excipients. The invention also provides the use of the solid medicinal composition in the preparation of oral liquid medicines and further provides a liquid medicinal composition which comprises the solid medicinal composition provided by the invention and a water-containing medium. When prepared into suspension with water, the solid medicinal composition has a stable advantage.

Description

technical field [0001] The present invention relates to a novel pharmaceutical composition of oseltamivir phosphate. Background technique [0002] Neuraminidase (NA) inhibitors are a class of anti-influenza virus drugs developed in recent years. As a newly developed neuraminidase inhibitor, oseltamivir phosphate is effective against both type A and type B influenza viruses, It is not easy to drug resistance, well tolerated by patients, and has high safety. It is clinically used for the prevention and treatment of influenza. [0003] Oseltamivir (Oseltamivir, used as its phosphate salt) is a therapeutic drug for the prevention and control of influenza pandemics by the World Health Organization and the Ministry of Health of my country, and it is also a national strategic reserve drug for the prevention and control of influenza pandemics in my country and other countries in the world. [0004] At present, in my country, the commercially available oseltamivir phosphate dosage f...
