FLUOCET vs POHERDY
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) that potentiates serotonergic activity in the CNS by blocking the reuptake of serotonin into presynaptic neurons.
POHERDY is a monoclonal antibody targeting the human epidermal growth factor receptor 2 (HER2), binding to domain IV of the extracellular segment, thereby inhibiting ligand-independent HER2 signaling and mediating antibody-dependent cellular cytotoxicity (ADCC).
20 mg orally once daily in the morning.
POHERDY: No approved drug. No dosing available.

Fluoxetine: 4-6 days (single dose), 4-6 days (chronic); Norfluoxetine: 16 days. Clinical context: Steady state achieved after 4-5 weeks; extended half-life reduces withdrawal risk but prolongs washout.
Terminal half-life 12–18 hours (mean 15 h); requires dose adjustment in renal impairment (CrCl <30 mL/min)
Renal: 80% as fluoxetine and its metabolites (60% as glucuronide conjugates, 20% as parent and norfluoxetine). Fecal: 15% (biliary).
Renal: 60% unchanged; fecal/biliary: 30%; 10% metabolized
