APLENZIN vs QMIIZ ODT
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.
QMIIZ ODT is a centrally acting alpha-2 adrenergic agonist that modulates norepinephrine release by binding to presynaptic alpha-2 adrenergic receptors, reducing sympathetic outflow from the brainstem and lowering blood pressure.
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.
20 mg sublingually once daily in the morning.

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 10–12 hours in healthy adults, allowing once-daily dosing.
Primarily renal (87% recovered in urine) with 10% fecal elimination. Unchanged bupropion accounts for <1% of renal excretion; metabolites (hydroxybupropion, threohydrobupropion, erythrohydrobupropion) predominate.
Primarily renal (90% as unchanged drug in urine), with minor fecal excretion (<5% as metabolites).
