EPRONTIA vs VIGPODER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective serotonin reuptake inhibitor (SSRI); potentiates serotonergic activity in the CNS by inhibiting presynaptic serotonin reuptake.
VIGPODER (vigabatrin) is an irreversible inhibitor of GABA transaminase, leading to increased brain levels of gamma-aminobutyric acid (GABA), a major inhibitory neurotransmitter.
Adults: 200-800 mg twice daily orally, starting at 200 mg twice daily, increasing by 200 mg/day weekly to maintenance.
150 mg orally twice daily with or without food.

Terminal elimination half-life is 20–30 hours in adults with normal renal function; prolonged to 40–60 hours in moderate to severe renal impairment (CrCl <50 mL/min), requiring dose adjustment.
12 hours (range 10–14 hours) in healthy adults; prolonged to 24–30 hours in moderate renal impairment (CrCl 30–50 mL/min).
Renal excretion of unchanged drug accounts for approximately 70% of elimination, with 30% metabolized hepatically; metabolites are also renally excreted. Fecal elimination is minimal (<5%).
Renal: 70% as unchanged drug; biliary/fecal: 20% as metabolites; 10% via other routes.
