Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective serotonin reuptake inhibitor (SSRI); paroxetine is the active ingredient. Enhances serotonergic activity by blocking serotonin reuptake into presynaptic neurons, augmenting serotonin levels in the synaptic cleft.
Selective serotonin reuptake inhibitor (SSRI); potentiates serotonergic activity in the CNS by blocking the reuptake of serotonin at the presynaptic neuronal membrane, resulting in increased serotonin concentrations in the synaptic cleft.
8 mg orally once daily, taken at bedtime.
50 mg orally once daily, increased by 50 mg increments at 1-week intervals up to 200 mg/day for depression, OCD, panic disorder, PTSD, PMDD, social anxiety disorder.

Terminal elimination half-life is approximately 9-11 hours for paroxetine (the active ingredient in Brisdelle). This supports once-daily dosing; steady-state is achieved within 7-14 days.
26 hours (terminal elimination half-life); steady state achieved in ~1 week; metabolite desmethylsertraline half-life 66 hours.
Primarily renal excretion as metabolites; approximately 60% of a radiolabeled dose is recovered in urine and 30% in feces over 10 days. Less than 1% excreted unchanged.
Renal: <0.5% unchanged; extensive hepatic metabolism; metabolites excreted renally and fecally.
