BRISDELLE vs PEXEVA
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.
Paroxetine is a selective serotonin reuptake inhibitor (SSRI); it potentiates serotonergic activity in the CNS by inhibiting the reuptake of serotonin at the presynaptic neuronal membrane.
8 mg orally once daily, taken at bedtime.
Initial 10 mg orally once daily, increased gradually based on response and tolerability; maximum 50 mg once daily (paroxetine hydrochloride equivalent).

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.
60-120 hours (chronic dosing); steady-state achieved in 4-5 weeks
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.
Primarily renal (70% as metabolites, 2% unchanged); fecal (27%)
