Abstract

The invention relates to application of Yinhua Miyanling Pian in preparation of a drug for reversing drug resistance of escherichia coli, belonging to the field of a drug. The Yinhua Miyanling Pian is applied to preparing the drug for inducing the drug resistance of escherichia coli under the pressure of levofloxacin. The bacteria passaged by a drug combination group of the Yinhua Miyanling Pian and the levofloxacin can not generate mutation of parC genes, which shows that the Yinhua Miyanling Pian is capable of reversing the drug resistance of the bacteria caused by antibiotics.
