MULTISOL AEROSOL SPRAY

MECHANISM OF ACTION OF BACITRACIN BACITRACIN IS AN ANTIBIOTIC PRODUCED BY THE STRAIN OF BACILLUS SUBTILIS. IT ACTS BY INHIBITING BACTERIAL CELL WALL SYNTHESIS. IT IS ACTIVE AGAINST A VARIETY OF GRAM POSITIVE AND A FEW GRAM NEGATIVE ORGANISMS. MECHANISM OF ACTION OF NEOMYCIN AMINOGLYCOSIDES LIKE NEOMYCIN "IRREVERSIBLY" BIND TO SPECIFIC 30S-SUBUNIT PROTEINS AND 16S RRNA. SPECIFICALLY NEOMYCIN BINDS TO FOUR NUCLEOTIDES OF 16S RRNA AND A SINGLE AMINO ACID OF PROTEIN S12. THIS INTERFERES WITH DECODING SITE IN THE VICINITY OF NUCLEOTIDE 1400 IN 16S RRNA OF 30S SUBUNIT. MECHANISM OF ACTION OF POLYMYXIN B POLYMYXIN B SULFATE HAS A BACTERICIDAL ACTION AGAINST ALMOST ALL GRAM-NEGATIVE BACILLI EXCEPT THE PROTEUS GROUP. POLYMYXIN B SULFATE INTERACTS WITH THE LIPOPOLYSACCHARIDE OF THE CYTOPLASMIC OUTER MEMBRANE OF GRAM-NEGATIVE BACTERIA ALTERING MEMBRANE PERMEABILITY AND CAUSING CELL DEATH. IT DOES NOT NEED TO ENTER THE CELL.
