摘要: Carbapenems differ from conventional penicillins (penams) in having no sulfur atom their 5-membered ring and a double bond between carbons 2 3 (figure 1). Imipenem, the first commercially-available carbapenem, (Merck Sharp Dohme) has been used for nearly 10 years is now being joined by second agent, meropenem (Zeneca/Sumitomo). The development of third biapenem (Lederle) recently discontinued. In contrast to all useful cephalosporins, various experimental carbapenems, these three agents carry substituents β-lactam trans configuration. This factor critical β-lactamase stability carbapenems.1
