Penicillinase-resistant penicillins

Cloxpen 500 mg inhibits bacterial cell wall synthesis by binding to 1 or more of the penicillin-binding proteins (PBPs) which in turn inhibit the final transpeptidation step of peptidoglycan synthesis in bacterial cell walls. Bacteria eventually lyse due to ongoing activity of cell wall autolytic enzymes (autolysins and murein hydrolases) while cell wall assembly is arrested.

May diminish the effect of BCG and typhoid vaccine. May increase risk of methotrexate toxicity. May diminish the therapeutic effect of Na picosulfate. May decrease serum concentrations of mycophenolate. May prolong bleeding time with anticoagulants. Increased serum concentrations with probenecid. Tetracycline may antagonise the bactericidal effect of Cloxpen 500 mg.

Cloxpen 500 mg should not be given to patients known to be hypersensitive to penicillin.

Common side effects are skin rash, transient diarrhoea, nausea, heartburn, pruritus and disturbance of blood electrolyte. Rarely anaphylactic shock.
