Bind to the membrane and cause rapid depolarization, resulting in a loss of
membrane potential leading to inhibition of protein, DNA and RNA synthesis
Macrolides

destabilizes the outer membrane. They act
like a detergent against the cytoplasmic membrane, which alters its permeability. Polymyxin B and E are bactericidal even in an isosmotic solution. Quinolones
