However, imipenem, which first appeared as a carbapenem antibiotic, exhibits excellent antibacterial activity against a wide range of Gram-positive and Gram-negative bacteria, but in vivo renal dehydropeptidase (DH).
P) has a drawback that decomposition / inactivation occurs in a short time. Therefore, imipenem cannot be administered alone and must be used in combination with a DHP inhibitor to suppress its degradation and inactivation. Therefore, a practical formulation of this compound is a DHP inhibitor, cilastatin (I).
It is a combination prescription of imipenem / cilastatin in combination with NN).

Needless to say, it is better to avoid compounding and prescribing as much as possible, as it may be exerted. Therefore, there has been a strong demand for the development of a carbapenem compound having antibacterial activity and resistance to DHP.
