Which carbapenem requires daily administration via IV/IM?

Ertapenem is the carbapenem that requires daily administration via IV/IM. This is primarily due to its pharmacokinetic profile, which allows for effective once-daily dosing. Ertapenem has a longer half-life compared to other carbapenems, making it convenient for once-daily dosing. This dosing schedule can improve patient compliance and ease of administration, especially in outpatient settings. In contrast, drugs like Imipenem and Meropenem typically require more frequent dosing due to their shorter half-lives. Cilastatin is not a carbapenem itself but rather a protective agent that inhibits the enzyme dehydropeptidase, which can inactivate Imipenem. Thus, it does not pertain to the question regarding administration frequency of carbapenems.
