It contains three antibiotics&colon; neomycin, polymyxin B, and bacitracin. The use of neomycin/polymyxin B/bacitracin, decreases infection rates in minor-contaminated wounds. Protein synthesis inhibitors include the antibiotic neomycin and the toxin ricin. Chinchillas may be treated with chloramphenicol, neomycin, or spectinomycin for digestive problems. The antibiotics neomycin and metronidazole are other antibiotics used to treat hepatic encephalopathy. In most countries, neomycin and chloramphenicol eye drops are used, instead. It is mostly used in complex ointments containing neomycin, nystatin, Thiostrepton and topical steroids. This class includes kanamycin, neomycin, gentamicin, apramycin, hygromycin. Physicians sometimes recommend using antibiotic ointments without neomycin, such as Polysporin. Streptomycin, neomycin, erythromycin and tetracycline are only a few examples of these antibiotics. The aminoglycosides, neomycin and paromomycin, have been found to reduce gastrointestinal (GI) absorption of methotrexate. Like neomycin, polymyxin B is an antibiotic. G418 is an analog of neomycin sulfate, and has similar mechanism as neomycin. Aside from fusidic acid, neomycin, mupirocin, metronidazole, and chlorhexidine are alternative options in this scenario. These include common antibiotics such as Neomycin and Polymyxin B.
