APLENZIN vs TRINTELLIX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bupropion is an aminoketone antidepressant that inhibits the reuptake of norepinephrine and dopamine, with no significant effect on serotonin. The exact mechanism of antidepressant action is unknown but is thought to be mediated by noradrenergic and dopaminergic pathways.
Trintellix (vortioxetine) is a serotonin modulator and reuptake inhibitor. Its exact mechanism is not fully understood, but it is thought to work by inhibiting the reuptake of serotonin (5-HT) and by modulating several serotonin receptors, including 5-HT1A agonism, 5-HT1B partial agonism, 5-HT3 and 5-HT7 antagonism.
APLENZIN (bupropion hydrobromide) extended-release tablets: Initial dose 174 mg orally once daily in the morning; after 4 days, increase to 348 mg once daily. Maximum dose 348 mg/day.
10 mg orally once daily initially, then increase to 20 mg orally once daily based on tolerability; maximum 20 mg/day.

Mean terminal half-life of bupropion is 21 hours (SD ±9 hours). Steady state achieved within 8 days. Metabolites have longer half-lives: hydroxybupropion ~24 hours, threohydrobupropion ~37 hours, erythrohydrobupropion ~34 hours.
Terminal elimination half-life is approximately 66 hours (range 58-78 hours) for vortioxetine. This supports once-daily dosing; steady-state is reached within 2-3 weeks.
Primarily renal (87% recovered in urine) with 10% fecal elimination. Unchanged bupropion accounts for <1% of renal excretion; metabolites (hydroxybupropion, threohydrobupropion, erythrohydrobupropion) predominate.
Primarily hepatic metabolism via CYP3A4 and CYP2C19, with approximately 26% of the dose recovered in urine (mostly as metabolites) and 60% in feces (mostly as metabolites). Less than 1% excreted as unchanged drug in urine.
