Paroxetine Hydrochloride Clinical Pharmacology & DailyMed Monograph

RxCUI 32937 • NDC 00378-7002-93

Highest biochemical SERT binding affinity (Ki ~0.13 nM) in the SSRI class; approved both at 20–40 mg for severe social/panic anxiety and at ultra-low 7.5 mg (Brisdelle) as a non-hormonal hypothalamic thermoregulatory treatment for menopausal vasomotor hot flashes.

CMS National Average Drug Acquisition Cost (NADAC) tracking places Paroxetine Hydrochloride (Paxil / Brisdelle (7.5 mg vasomotor), RxCUI 32937) at $0.0520 per unit, whereas walk-in chain pharmacies bill cash patients an average of $36.00 monthly—creating a 85% ($30.50/mo) wholesale arbitrage spread down to $5.50.

Systemic exposure to Paroxetine Hydrochloride reflects 64% oral after saturable first-pass absorption kinetics and potent cyp2d6 mechanism-based inhibitor (never combine with tamoxifen—blocks endoxifen activation!), sustaining receptor engagement across a 21 hours (non-linear autoinhibition of CYP2D6) half-life window (2 weeks vasomotor hot-flash drop; 3–4 weeks panic control response profile).

Dosing protocols (7.5 mg PO QHS (non-hormonal vasomotor hot flashes) or 10–20 mg PO daily or 40 mg PO daily) balance efficacy (76.40% patient satisfaction across 27 logs) against discontinuation dizziness without slow taper (33% of reports), weight gain (28% of reports), anticholinergic dry mouth (19% of reports), with strict avoidance in tamoxifen co-administration (abolishes cyp2d6 endoxifen breast-cancer protection); maoi within 14 days; first-trimester pregnancy (cardiac septal risk).
