Neomycin 20% WSP is a bactericidal Amino-glycoside which antibacterial action result by fixation on subunit 30S of bacterial ribosome. It impede the initiation phase of bacterial growth, provokes disturbance in mRNA ordinance and incorrect lecture of bacterial genetic
Code affected by tRNA. It acts inside the cell by binding to the ribosome in such a way that incorrect amino acid sequences are entered into peptide chains. The abnormal proteins that result are fatal to the microbe. It also modifies the permeability of the bacterial cell membrane.
