What kind of infections does cloxacillin treat?

Cloxacillin is prescribed for various infections, including skin and soft tissue infections, bone and joint infections, respiratory tract infections, and endocarditis, when caused by susceptible bacteria [3][4]. Its primary use is against strains of Staphylococcus that produce the enzyme penicillinase, which would otherwise inactivate other penicillin antibiotics [2].

How does cloxacillin work?

As a beta-lactam antibiotic, cloxacillin works by inhibiting the synthesis of the bacterial cell wall [5]. It binds to penicillin-binding proteins (PBPs) that are essential for building the peptidoglycan layer of the bacterial cell wall. This inhibition leads to cell lysis and bacterial death [6].
