Product Description:

Oxacillin is a semisynthetic, penicillinase-resistant β-lactam antibiotic that is closely related to methicillin and has largely replaced it in clinical practice. It is part of a class of antibiotics that includes nafcillin, cloxacillin, dicloxacillin, and flucloxacillin. Oxacillin is specifically designed to resist degradation by penicillinase enzymes produced by bacteria such as Staphylococcus aureus, making it highly effective for treating infections caused by penicillin-resistant strains of this bacterium.

Clinically, oxacillin is widely used in the United States to treat serious staphylococcal infections, including skin and soft tissue infections, bone and joint infections, endocarditis, and sepsis. Its mechanism of action involves inhibiting bacterial cell wall synthesis, leading to cell lysis and death. However, the extensive use of oxacillin has contributed to the emergence of methicillin-resistant and oxacillin-resistant Staphylococcus aureus (MRSA/ORSA), which are increasingly prevalent worldwide. These resistant strains require alternative treatments, such as vancomycin or newer antibiotics, to effectively manage infections. Oxacillin remains a cornerstone therapy for penicillinase-producing staphylococcal infections when the bacteria are susceptible, offering reliable efficacy and a well-established safety profile.
