: any of a class of broad-spectrum beta-lactam antibiotics (such as imipenem) having a five-membered ring system similar to the penicillins but containing a carbon atom instead of a sulfur atom It rendered the Klebsiella, which was already resistant to many antibiotics used in critical care medicine, insensitive to the only remaining group that worked reliably and safely—the carbapenems, the so-called drugs of last resort.—Maryn McKenna, Scientific American, April 2011
