Biological Activity
| Description | Meropenem (SM 7338) is an ultra-broad spectrum injectable antibiotic. |
|---|---|
| In vitro | Meropenem has an antibacterial spectrum which is broadly similar to that of imipenem but, whilst slightly less active against staphylococci and enterococci, it is more active against Pseudomonas aeruginosa, all Enterobacteriaceae and Haemophilus influenzae. [1] Meropenem is two- to four-fold more active than imipenem against Gram-negative organisms and its spectrum of antimicrobial activity is wider than those of all other drugs tested. Meropenem MICs are not significantly influenced by high inocula and the drug is generally bactericidal. Meropenem demonstrates antagonism with several other beta-lactams against strains producing Type I cephalosporinases. [2] Meropenem binds most strongly to penicillin-binding protein 2 of Escherichia coli and Pseudomonas aeruginosa, and to penicillin-binding proteins 1 of Staphylococcus aureus. [3] Meropenem is a new carbapenem antibiotic which differs chemically from imipenem/cilastatin by having a 1-beta-methyl substitution, providing it with excellent intrinsic stability to human renal dehydropeptidase-I. Meropenem has one identified metabolite, a beta-lactam ring-opened form which is devoid of microbiological activity. [4] |
| In vivo | Meropenem significantly increases the plamsa total clearance of valproate to about 1.5 times the control (6.09 mL/min/kg vs. 4.28 mL/min/kg) in rabbits. Meropenem significantly increases the urinary excretion of valproate- glucuronide in rabbits. [5] |
