COMPAZINE vs EMRELIS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dopamine D2 receptor antagonist in the chemoreceptor trigger zone; also blocks alpha-1 adrenergic, histamine H1, and muscarinic M1 receptors.
Emrelis is a monoclonal antibody that inhibits the interaction between programmed cell death protein 1 (PD-1) and its ligands PD-L1 and PD-L2, thereby activating T-cell-mediated antitumor immune response.
5-10 mg IM/IV every 3-4 hours as needed; or 25 mg PO/PR twice daily for severe nausea/vomiting.
100 mg subcutaneously once weekly.
