Cloxacillin

What is Cloxacillin?

Cloxacillin is a semi-synthetic antibiotic that belongs to the penicillin class of medications. It is used to treat various bacterial infections, particularly those caused by susceptible strains of Streptococcus and Staphylococcus bacteria. Cloxacillin has a broad spectrum of activity against Gram-positive bacteria but is less effective against Gram-negative organisms. The medication is typically administered orally or intravenously for moderate to severe bacterial infections and is considered an intermediate-acting penicillin antibiotic, with a duration of action that lasts approximately 6 hours.

What is Cloxacillin used for?

Cloxacillin is an oral cephalosporin antibiotic, a type of beta-lactam antimicrobial agent that belongs to the first generation of this class. Structurally similar to methicillin and penicillin G, cloxacillin has been used in the treatment of various bacterial infections, particularly those caused by Staphylococcus aureus, Streptococcus pyogenes, and Escherichia coli. As an antimicrobial agent, cloxacillin exerts its bacteriolytic action through inhibition of cell wall synthesis in susceptible bacteria.

Cloxacillin’s effectiveness stems from its ability to inhibit the bacterial enzyme penicillin-binding protein (PBP), a key target for beta-lactam antibiotics. This mechanism prevents the bacteria from producing their cell walls, ultimately leading to their death or lysis. Clinically, cloxacillin has been administered orally and intravenously in various clinical settings, including urinary tract infections, skin and soft tissue infections, respiratory tract infections, septicemia, and bone and joint infections. Cloxacillin’s efficacy and pharmacokinetic profile have positioned it as a valuable option for the treatment of bacterial infections.
