Doripenem is a new parental 1-beta-methyl carbapenem which, unlike imipenem, does not require the addition of cilastatin on administration because of the protection afforded to doripenem by the 1-beta-methyl component. It combines the in vitro activities of imipenem and ertapenem against gram-positive bacteria with the in vitro activity of meropenem against gram-negative bacteria. It has excellent bactericidal activity against Streptococcus neumoniae. Carbapenem resistant mutants were selected with less frequency and lower minimum inhibitory concentrations (MICs) after exposure to doripenem than to imipenem or meropenem. High concentration levels of doripenem may be achieved in plasma. The half life of doripenem is higher than imipenem or meropenem. This new antibiotic has excellent in vitro activity and pharmacological properties. but how it may best be utilized still needs to be determined.
多利培南是一种新型的母体 1-β-甲基碳青霉烯类抗生素,与亚胺培南不同,由于 1-β-甲基成分的保护,多利培南不需要在给药时添加西司他丁。它结合了亚胺培南和厄他培南对革兰氏阳性菌的体外活性,以及美罗培南对革兰氏阴性菌的体外活性。它对肺炎链球菌具有极好的杀菌活性。与亚胺培南或美罗培南相比,多利培南暴露后选择碳青霉烯耐药突变体的频率较低,最低抑菌浓度(MIC)也较低。多利培南在血浆中的浓度可能很高。多利培南的半衰期高于亚胺培南或美罗培南。这种新型抗生素具有极好的体外活性和药理学特性。但如何最好地利用它仍有待确定。
