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.
Venlafaxine is a serotonin-norepinephrine reuptake inhibitor (SNRI). It potently inhibits the reuptake of serotonin and norepinephrine, and weakly inhibits dopamine reuptake. It has no significant affinity for muscarinic, histaminergic, or alpha1-adrenergic receptors.
60 mg orally once daily, with or without food. Capsules may be swallowed whole or opened and sprinkled onto applesauce.
75 mg orally once daily; may increase by 75 mg/day increments every 4-7 days to max 225 mg/day.

12-15 hours; steady-state achieved in 2-3 days; no significant accumulation with q12h dosing.
Venlafaxine: 3-7 hours (short, requires extended-release formulation for once-daily dosing); active metabolite O-desmethylvenlafaxine: 9-13 hours (contributes to overall clinical effect). Steady-state achieved within 3 days.
Primarily renal (approx. 70% as unchanged drug and metabolites); 30% fecal/biliary.
Renal: approximately 87% as metabolites (including venlafaxine, O-desmethylvenlafaxine, and other minor metabolites) and ≤5% as unchanged drug. Biliary/fecal: minimal (about 2%).
