Mode of Action
Gramicidin is an antibacterial which is too toxic to be used systemically, so it is rather used as a topical and ophth agent and in combination with other antibacterials (neomycin and polymixin B) and also with corticosteroids.
Neomycin is an aminoglycoside antibiotic. It binds to 30S ribosomal subunits of bacterial ribosome thus inhibiting protein synthesis and generating errors in genetic code transcription causing cell death. It acts against many gram-negative aerobes and some gram-positive aerobes. It lacks activity against fungi, viruses and most anaerobic bacteria.
Polymyxin B disrupts the bacterial cytoplasmic membrane of mostly gm-ve organisms allowing leakage of intracellular constituents by binding to membrane phospholipids.
