Biochem/physiol Actions
Carbapenem class broad-spectrum β-lactam antibiotic, active metabolite of Tebipenem pivoxil (L-084I; SPR994; Tebi-pivoxil; TBM-P).
Tebipenem (LJC 11,036; SPR859; TBM) is a carbapenem class broad-spectrum β-lactam antibiotic against both gram-positive and gram-negative bacteria, including penicillin-resistant S. pneumoniae (PRSP) and many β-lactamase-producing strains (respective MIC ≤6-200 and ≤25-390 ng/mL), while being less effective against methicillin-resistant S. aureus (MRSA), S. marcescens, and P. aeruginosa (respective MIC ranges 0.2 to12.5, 0.05 to100, 3.13 to >100 μg/mL). TBM is 2- to 64-fold more potent than imipenem, cefdinir, and faropenem against clinical isolates from respiratory and urinary-tract infections.
