Moxalactam (latamoxef) is a new synthetic oxa-beta-lactam antibiotic administered intravenously or intramuscularly. It has a broad spectrum of activity against Gram-positive and Gram-negative aerobic and anaerobic bacteria, is particularly active against Enterobacteriaceae and is resistant to hydrolysis by beta-lactamases. Moxalactam has moderate activity against Pseudomonas aeruginosa, but on the basis of present evidence can not be recommended as sole antibiotic treatment of known or suspected pseudomonal infections. Like the related compounds, the cephalosporins, moxalactam is effective in the treatment of complicated urinary tract infections and lower respiratory tract infections caused by Gram-negative bacilli. Latamoxef works by inhibiting bacterial cell wall biosynthesis. Latamoxef is primarily indicated in conditions like Bone and joint infection, GI infections, Gynecological infections, Meningitis, Respiratory tract infections, Septicaemia, Skin infections, Soft tissue infections, UTI. Latamoxef is no longer available in the United States.
