Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Trastuzumab deruxtecan is a HER2-targeted antibody-drug conjugate (ADC). The antibody binds to HER2 on tumor cells, leading to internalization and intracellular release of the topoisomerase I inhibitor payload (DXd), which causes DNA damage and apoptosis.
Rimantadine is a tricyclic amine antiviral that inhibits influenza A virus replication by blocking the M2 proton ion channel, preventing viral uncoating and release of viral RNA into host cells.
