详细说明

DrugBank - DB00948

• Drug Groups: approved
• Description: Semisynthetic ampicillin-derived acylureido penicillin. It has been proposed for infections with certain anaerobes and may be useful in inner ear, bile, and CNS infections. [PubChem]
• Indication: Used to treat serious gram–negative infections of the lungs, urinary tract, and skin.
• Pharmacology: Mezlocillin is a penicillin beta-lactam antibiotic used in the treatment of bacterial infections caused by susceptible, usually gram-positive, organisms. The name "penicillin" can either refer to several variants of penicillin available, or to the group of antibiotics derived from the penicillins. Mezlocillin has in vitro activity against gram-positive and gram-negative aerobic and anaerobic bacteria. The bactericidal activity of mezlocillin results from the inhibition of cell wall synthesis and is mediated through mezlocillin binding to penicillin binding proteins (PBPs). Mezlocillin is stable against hydrolysis by a variety of beta-lactamases, including penicillinases, and cephalosporinases and extended spectrum beta-lactamases. Mezlocillin can be used to treat susceptible strains of H. influenzae, Klebsiella species, Pseudomonas species, Proteus mirabilis, E. coli, Enterobacter species, Streptococcus faecelis, Peptococcus species, Peptostreptococcus species, Bacteriodes species (including B. fragilis), Morganella morganii, Serratia species, N. gonorrhoeae, P. vulgaris, and Providencia rettgeri. This drug is discontinued in the U.S.
• Toxicity: Symptoms of overdose include rash, fever, chills, and peeling skin.
• Affected Organisms: Enteric bacteria and other eubacteria
• Biotransformation: Unlike many other penicillins, mezlocillin is either extensively metabolized or is subject to biliary excretion, as only about 50% of the dose was accounted for in normal urine.
• Half Life: 1.3 to 4.4 hours
• Protein Binding: 16-59%
