Pharmacology
- Indication
Used to treat serious gram–negative infections of the lungs, urinary tract, and skin.
- Pharmacodynamics
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.
- Mechanism of action
By binding to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, mezlocillin inhibits the third and last stage of bacterial cell wall synthesis. Cell lysis is then mediated by bacterial cell wall autolytic enzymes such as autolysins; it is possible that mezlocillin interferes with an autolysin inhibitor.

Drug Interaction (R)-warfarin Mezlocillin may increase the anticoagulant activities of (R)-warfarin. (S)-Warfarin Mezlocillin may increase the anticoagulant activities of (S)-Warfarin. 4-hydroxycoumarin Mezlocillin may increase the anticoagulant activities of 4-hydroxycoumarin. Acemetacin Acemetacin may decrease the excretion rate of Mezlocillin which could result in a higher serum level. Acenocoumarol Mezlocillin may increase the anticoagulant activities of Acenocoumarol. Adenovirus type 7 vaccine live The therapeutic efficacy of Adenovirus type 7 vaccine live can be decreased when used in combination with Mezlocillin. Alcuronium The therapeutic efficacy of Alcuronium can be increased when used in combination with Mezlocillin. Amikacin The serum concentration of Amikacin can be decreased when it is combined with Mezlocillin. Anthrax immune globulin human The therapeutic efficacy of Anthrax immune globulin human can be decreased when used in combination with Mezlocillin.
