Abstract

Atomoxetine hydrochloride, a selective norepinephrine reuptake inhibitor, and oxybutynin chloride, a muscarinic antagonist, have recently gained attention not only for their primary therapeutic applications—attention-deficit/hyperactivity disorder (ADHD) and overactive bladder, respectively—but also for their synergistic role in managing obstructive sleep apnea (OSA). This review provides a comprehensive overview of their physicochemical properties, mechanisms of action, and clinical relevance in OSA. In addition, it summarizes official pharmacopeial methods (IP, USP, BP) and reported analytical techniques, including HPLC, RP-HPLC, HPTLC, spectrophotometry, and micellar liquid chromatography, for the estimation of both drugs individually and in combination with other agents. Critical evaluation of chromatographic parameters, detection wavelengths, and mobile phases highlights the advancements and challenges in method development and validation. This review underlines the significance of robust, sensitive, and stability-indicating methods for routine quality control and pharmacokinetic studies, offering a consolidated reference for researchers and analysts working on atomoxetine and oxybutynin.
