The correct answer is B

The main drug in the carbapenam class is a drug called IMIPENEM – this drug has excellent, quite broad antimicrobial activity against both g+ and g- organisms, anaerobes, and Psuedomonas infections; it is given with a molecule called cilastatin, which is an inhibitor of the renal enzyme dehydropeptidase – this renal enzyme would otherwise break down the drug too quickly, and would make the drug ineffective in the treatment of UTI’s – thus by giving imipenem with the cilastatin, the half life of the drug is prolonged and it can be used to treat UTI’s.
