Carbapenems
Broadest-spectrum beta-lactam cell-wall class
kar-buh-PEN-ems
High-yield clue
Beta-lactams stable against many ESBLs, so carbapenem resistance via carbapenemases defines the CRE study concept.
Overview
A beta-lactam antimicrobial class (imipenem, meropenem, ertapenem, doripenem) studied for the broadest spectrum among beta-lactams and for its central role in carbapenem-resistance vocabulary.
Classification
- Beta-lactam
- Bactericidal
- Binds penicillin-binding proteins (PBPs)
- Inhibits peptidoglycan cross-linking
Lab & identification clues
- Carbapenemase production vocabulary (KPC, NDM, OXA-48, VIM, IMP)
- Modified carbapenem inactivation concept
- MIC-based susceptibility interpretation
- Imipenem paired with cilastatin to block renal dehydropeptidase
Associations
- Carbapenem-resistant Enterobacterales (CRE) framing
- Reserved / last-resort stewardship vocabulary
- Broad Gram-positive, Gram-negative, and anaerobe coverage concept
Commonly confused with
- Monobactams (aztreonam)
- Cephalosporins
