It acts as a bactericidal antibiotic that interferes with phospholipids of bacterial cell wall and promotes the leakage of intracellular components that leads to subsequent cell death. It acts against gram-negative organisms mainly that include P. aeruginosa, E.coli, Klebsiella species and Enterobacter.
It interferes with the incorporation of amino acid into cell walls that leads to no bacterial cell growth. It mainly acts on gram negative bacteria such as staphylococci, streptococci, anaerobic cocci, corynebacteria, and clostridia.
