Answer:
c. in renal dysfunction, dosage reduction is necessary to avoid seizures
Explanation:
Imipenem is an antibiotic which is given in combination with cilastatin. It is used to treat pneumonia, joint infections, urinary tract infections, sepsis etc. It kills bacteria by interfering with its cell wall formation process. It is metabolized in kidney reducing its half life so cilastatin is given with it to halt its renal metabolism.
