Abstract

The invention relates to suspensoid powder injection of a piperacillin sodium sulbactam medicine composition prepared by applying an emulsification suspensoid technology and freeze drying. The invention further relates to a novel application of the suspensoid powder injection in preparing a medicine treating the infection of the oral cavity.

Description

technical field [0001] The invention relates to a suspension powder injection of a piperacillin sodium sulbactam sodium medicinal composition, a preparation method and a new application thereof. Background technique [0002] The oral cavity is one of the ways for pathogenic microorganisms to invade the body. Because the temperature, humidity and food residues in the mouth are suitable for the growth and reproduction of microorganisms. There are a lot of germs in the mouth of normal people. After the operation, the patient's resistance is reduced, and the mouth drinks and eats less, which often makes the bacteria in the mouth multiply and easily causes oral infection. Under normal circumstances, there are more than ten kinds of bacterial flora in the oral cavity, and they restrict and depend on each other to maintain a relatively balanced oral pH of 6.6 to 7.1. Changes in pH in the oral cavity are associated with the incidence of stomatitis. When the pH is lowered, fungal ...
