IMKELDI vs NEMLUVIO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Imkelde (imipenem/cilastatin/relebactam) is a combination antibacterial agent. Imipenem inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs). Cilastatin inhibits renal dehydropeptidase I, preventing renal metabolism of imipenem. Relebactam is a beta-lactamase inhibitor that protects imipenem from degradation by certain serine beta-lactamases, including KPC and some AmpC enzymes.
Nemolizumab is a humanized monoclonal antibody that binds to the interleukin-31 receptor alpha (IL-31RA), blocking IL-31 signaling. IL-31 is a cytokine involved in pruritus, inflammation, and barrier dysfunction in atopic dermatitis and other conditions.

Terminal elimination half-life: 12 hours (range 10-14 hours) in healthy adults; extended to 24-30 hours in moderate renal impairment (CrCl 30-50 mL/min). Clinical context: Steady state achieved after 3-4 days. Twice-daily dosing maintains therapeutic levels.
The terminal elimination half-life is approximately 40 hours (range 35-50 hours), supporting once-daily dosing for sustained therapeutic effect.
Primarily renal excretion of unchanged drug and metabolites; 70% recovered in urine (60% unchanged, 10% as glucuronide conjugate) and 30% in feces (mainly metabolites) over 72 hours.
Renal excretion of unchanged drug accounts for approximately 30% of the administered dose; fecal elimination via biliary excretion accounts for approximately 60%; the remainder is metabolized and excreted as metabolites.
