Neomycin/polymyxin B/bacitracin, also known as triple antibiotic ointment, is an antibiotic medication used to reduce the risk of infections following minor skin injuries. [ 1 ] [ 2 ] It contains the three antibiotics neomycin , polymyxin B , and bacitracin . [ 1 ]
Polymyxin B, sold under the brand name Poly-Rx among others, is an antibiotic used to treat meningitis, pneumonia, sepsis, and urinary tract infections. [1] While it is useful for many Gram negative infections, it is not useful for Gram positive infections. [ 1 ]
Neomycin comes in oral and topical formulations, including creams, ointments, and eyedrops. Neomycin belongs to the aminoglycoside class of antibiotics that contain two or more amino sugars connected by glycosidic bonds. Neomycin was discovered in 1949 by microbiologist Selman Waksman and his student Hubert Lechevalier at Rutgers University.
Polymyxin B1, in turn, comprises several isomers, like isoleucine-polymyxin B1 and B1-1. [15] The major impediment in the purification and isolation of one isomer is due to the minimal structural differences between Polymyxin B1 and B2, differing only in one carbon at the 6th position of the fatty acyl side chain linked to the D-Phenylalanine ...

Bacitracin is a polypeptide antibiotic derived from a bacterium, Bacillus subtilis, and acts against bacteria through the inhibition of cell wall synthesis. [6] It does this by inhibiting the removal of phosphate from lipid compounds, thus deactivating its function to transport peptidoglycan; the main component of bacterial cell membranes, to the microbial cell wall.
