ARYNTA vs OXAYDO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ARYNTA (pembrolizumab) is a humanized monoclonal antibody that binds to the programmed death-1 (PD-1) receptor on T cells, blocking its interaction with PD-L1 and PD-L2, thereby restoring anti-tumor immune responses.
Oxycodone is a full opioid agonist with relative selectivity for mu-opioid receptors, although it can bind to kappa-opioid receptors at higher doses. The principal therapeutic action of oxycodone is analgesia. Like all full opioid agonists, there is no ceiling effect to analgesia for oxycodone.
400 mg orally once daily
Oral, 5-10 mg every 4-6 hours as needed for pain; maximum 60 mg per day.

Terminal elimination half-life is 2-4 hours in healthy adults, prolonged to 6-12 hours in moderate to severe renal impairment (CrCl <30 mL/min).
Terminal elimination half-life is 3.5-5.5 hours for immediate-release oxycodone; clinically dose every 4-6 hours for sustained analgesia.
Primarily renal elimination (70-80% unchanged), with 10-15% fecal excretion via biliary secretion.
Primarily renal as unchanged drug and metabolites; ~90% excreted in urine (approx 10% unchanged oxycodone, rest as noroxycodone and oxymorphone conjugates) and <10% in feces via biliary elimination.
