Pharmacology

Mechanism of Action

Bacitracin: Inhibits bacterial cell wall synthesis by preventing the incorporation of amino acids and nucleotides into the cell wall

Neomycin: Interferes with bacterial protein synthesis by binding to 30S ribosomal subunits

Polymyxin B: Bactericidal; causes leakage of bacterial membrane

Hydrocortisone: Decrease inflammation by stabilizing leukocyte lysosomal membranes, preventing release of destructive acid hydrolases from leukocytes
