Drug Mode of Action ::  

Cefalexin binds to one or more of the penicillin-binding proteins (PBPs) which inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell wall, thus inhibiting biosynthesis and arresting cell wall assembly resulting in bacterial cell death.

Drug Interactions ::

Concurrent use w/ metfromin may result to fatal lactic acidosis. May enhance the anticoagulant effect of vit K antagonists (e.g. warfarin). Increased risk of nephrotoxicity w/ potent diuretics (e.g. ethacrynic acid, furosemide) and other potentially nephrotoxic antibiotics (e.g. aminoglycosides, polymyxin, colistin). Prothrombin time may be prolonged when used concomitantly w/ oral anticoagulants. May reduce the effects of OCs. Hypokalaemia may result from concomitant use of cefalexin and cytotoxic drugs for leukaemia. Uricosuric drugs (e.g. probenecid) may suppress renal excretion, resulting to increased plasma levels of cefalexin. May diminish the therapeutic effect of Na picosulfate, BCG and typhoid vaccine. May reduce serum level w/ multivitamins/minerals.
