描述：

Meropenem is an ultra-broad-spectrum injectable β-lactam antibiotic used to treat a wide variety of infections. Meropenem has been shown to inhibit penicillinase-negative, -positive and methicillin-susceptible staphylococci [1].

In vitro: The meropenem MICs for penicillin-resistant Streptococcus pneumoniae were higher than for the penicillin-susceptible strains but the organisms remained susceptible. Clinical susceptibility in vitro to meropenem was defined by MICs of ≤ 4 mg/L, intermediate susceptibility by MICs of 8 mg/L and MICs of ≥ 16 mg/L define resistance; equivalent figures for zones of growth inhibition were ≥ 14 (susceptible), 12-13 (intermediate) and ≤ 11 (resistant) mm[1].Meropenem was 2- to 4-fold more active than imipenem against Gram-negative organisms and its spectrum of antimicrobial activity was wider than those of all other drugs tested.Meropenem inhibited all anaerobic bacteria at less than or equal to 8 mg/l and 0.25 mg/l inhibited 50% of strains. Meropenem MICs were not significantly influenced by high inocula and the drug was generally bactericidal [2].Meropenem bound most strongly to penicillin-binding protein 2 of Escherichia coli and Pseudomonas aeruginosa, and to penicillin-binding proteins 1 of Staphylococcus aureus [3].Meropenem had one identified metabolite, a β-lactam ring-opened form which is devoid of microbiological activity[4].

In vivo: In rabbits, meropenem significantly increased the plamsa total clearance of valproate to about 1.5 times compared to the control (6.09 mL/min/kg vs. 4.28 mL/min/kg). Meropenem significantly increased the urinary excretion of valproate- glucuronide in rabbits [5].
