Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective serotonin reuptake inhibition, resulting in increased synaptic serotonin concentrations and enhanced serotonergic neurotransmission.
Inhibits serotonin and norepinephrine reuptake by blocking the serotonin transporter (SERT) and norepinephrine transporter (NET), increasing extracellular concentrations of serotonin and norepinephrine in the CNS.
60 mg orally once daily, with or without food. Capsules may be swallowed whole or opened and sprinkled onto applesauce.
Initial: 75 mg/day PO in 2-3 divided doses; may increase by 75 mg/day increments at intervals of 4 days or more; max 375 mg/day. Extended-release: initial 37.5-75 mg PO once daily, titrate up to max 225 mg/day.

12-15 hours; steady-state achieved in 2-3 days; no significant accumulation with q12h dosing.
Venlafaxine: ~5 ± 2 hours; ODV (active metabolite): ~11 ± 2 hours. At steady state, effective half-life for total active moiety (venlafaxine + ODV) is ~11 hours. Clinical context: requires twice-daily dosing for immediate-release; extended-release formulations allow once-daily dosing.
Primarily renal (approx. 70% as unchanged drug and metabolites); 30% fecal/biliary.
Primarily renal (≈87% of dose eliminated in urine), with approximately 29% as unchanged venlafaxine, 26% as unconjugated O-desmethylvenlafaxine (ODV), and the remainder as other metabolites. Fecal elimination accounts for <10%. Biliary excretion is negligible.
