Oxacillin

Description:

Oxacillin is a semisynthetic antibiotic belonging to the penicillin class, primarily used to treat infections caused by penicillinase-producing staphylococci. It is characterized by its beta-lactam structure, which is essential for its antibacterial activity. Oxacillin is effective against a range of Gram-positive bacteria, particularly Staphylococcus aureus, and is resistant to degradation by certain beta-lactamases, making it a valuable option in treating resistant infections. The compound is typically administered via injection or orally, depending on the formulation. Its pharmacokinetics involve rapid absorption, with peak plasma concentrations occurring shortly after administration. Oxacillin is metabolized in the liver and excreted primarily through the kidneys. Common side effects may include allergic reactions, gastrointestinal disturbances, and potential impacts on liver function. Due to its specific action against resistant strains, oxacillin remains an important tool in the antibiotic arsenal, although its use must be guided by susceptibility testing to ensure effectiveness and minimize resistance development.
