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 pharmaceutical composition of piperacillin sodium and sulbactam sodium, and a preparation method and new application thereof. Background technique [0002] The oral cavity is one of the ways that pathogenic microorganisms invade the body. Due to the temperature, humidity and food residue in the mouth, it is suitable for the growth and reproduction of microorganisms. There are a large number of bacteria in the oral cavity of normal people. After the operation, the patient's resistance to the oral cavity decreases, and the oral cavity drinks less water and eats less, which can often cause the bacteria in the oral cavity to multiply and easily cause oral infection. Under normal circumstances, there are more than a dozen bacterial groups in the oral cavity, which restrict and rely on each other to maintain a relative equilibrium. The oral pH is 6.6 to 7.1. The changes in oral pH are related to the in...
