EMTRIVA vs EMZAHH
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nucleoside reverse transcriptase inhibitor; emtricitabine is phosphorylated to emtricitabine 5'-triphosphate which competes with deoxycytidine 5'-triphosphate for incorporation into viral DNA, resulting in chain termination.
EMZAHH is a monoclonal antibody that targets and binds to the human epidermal growth factor receptor 2 (HER2), inhibiting downstream signaling pathways involved in cell proliferation and survival.
Emtricitabine 200 mg orally once daily.
10 mg orally twice daily without regard to meals.

Terminal elimination half-life 12 hours, requiring twice-daily dosing for steady state
Renal excretion of unchanged drug (~86%) by glomerular filtration and active tubular secretion; fecal excretion (<1%)
Renal 40% unchanged, fecal 50% as metabolites, biliary 10%
