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.
Gabapentin is a structural analog of GABA but does not bind to GABA receptors. It binds to the α2δ subunit of voltage-gated calcium channels, reducing calcium influx and decreasing the release of excitatory neurotransmitters.
Adults: 200-800 mg twice daily orally, starting at 200 mg twice daily, increasing by 200 mg/day weekly to maintenance.
Initial dose: 300 mg orally once daily on day 1, 300 mg twice daily on day 2, then 300 mg three times daily on day 3; titrate as needed up to 1800-3600 mg/day in three divided doses. Maximum single dose: 1200 mg. Dose adjustments for renal impairment should be made based on creatinine clearance.

Clinical Note
moderateGabapentin + Fluticasone propionate
"The risk or severity of adverse effects can be increased when Gabapentin is combined with Fluticasone propionate."
Clinical Note
moderateGabapentin + Erythromycin
"The metabolism of Erythromycin can be decreased when combined with Gabapentin."
Clinical Note
moderateGabapentin + Fluconazole
"The serum concentration of Fluconazole can be increased when it is combined with Gabapentin."
Clinical Note
moderateGabapentin + Clemastine
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.
5-7 hours (normal renal function); prolonged to 50-140 hours in end-stage renal disease; half-life independent of dose due to linear kinetics.
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: 76-81% unchanged in urine; biliary/fecal: <5% as metabolites; remainder (10-20%) as minor metabolites via urine.
