  • AdministrationN/A
  • PharmacologyAn acylampicillin antibiotic with an extended spectrum of activity and greater in vitro potency than the carboxy penicillins.
  • Absorption_value0.0
  • Absorption (description)Azlocillin is poorly absorbed from the gastro-intestinal tract but is widely distributed following intravenous administration in body tissues and fluids.

  • Blood/Plasma Partitioning ratio (D_blood)N/A
  • MetabollsmIt is metabolised to a limited extent
  • Half life1 h
  • ExcretionAbout 50 to 70% of a dose is excreted unchanged in the urine by glomerular filtration and tubular secretion. This occurs within 24 h of administration, therefore, producing high urinary concentrations. It is partly excreted in bile. Concomitant administration of probenecid increases plasma concentrations. It can be removed by haemodialysis.
