Armodafinil improves wakefulness and long-term episodic memory in nCPAP-adherent patients with excessive sleepiness associated with obstructive sleep apnea.

Roth T, Rippon GA, Arora S - Sleep Breath (2008)

Bottom Line: Armodafinil did not adversely affect desired nighttime sleep, and nCPAP use remained high (approximately 7 h/night).Adjunct treatment with armodafinil significantly improved wakefulness, long-term memory, and patients' ability to engage in activities of daily living in nCPAP-adherent individuals with ES associated with OSA.Armodafinil also reduced patient-reported fatigue and was well tolerated.

ABSTRACT
Residual excessive sleepiness (ES) and impaired cognition can occur despite effective and regular nasal continuous positive airway pressure (nCPAP) therapy in some patients with obstructive sleep apnea (OSA). A pooled analysis of two 12-week, randomized, double-blind studies in nCPAP-adherent patients with ES associated with OSA evaluated the effect of armodafinil on wakefulness and cognition. Three hundred and ninety-one patients received armodafinil (150 or 250 mg) and 260 patients received placebo once daily for 12 weeks. Efficacy assessments included the Maintenance of Wakefulness Test (MWT), Cognitive Drug Research cognitive performance battery, Epworth Sleepiness Scale, and Brief Fatigue Inventory. Adverse events were monitored. Armodafinil increased mean MWT sleep latency from baseline to final visit by 2.0 min vs a decrease of 1.5 min with placebo (P < 0.0001). Compared with placebo, armodafinil significantly improved quality of episodic secondary memory (P < 0.05) and patients' ability to engage in activities of daily living (P < 0.0001) and reduced fatigue (P < 0.01). The most common adverse events were headache, nausea, and insomnia. Armodafinil did not adversely affect desired nighttime sleep, and nCPAP use remained high (approximately 7 h/night). Adjunct treatment with armodafinil significantly improved wakefulness, long-term memory, and patients' ability to engage in activities of daily living in nCPAP-adherent individuals with ES associated with OSA. Armodafinil also reduced patient-reported fatigue and was well tolerated.

Mentions: Compared with placebo, armodafinil significantly improved the quality of episodic secondary memory across the first four tests (09:30, 11:30, 13:30, 15:30) at all study visits (P < 0.05; Fig. 3a). The mean (SD) change from baseline in quality of episodic secondary memory at final visit was 10.2 (31.7) U for the armodafinil group compared with −0.7 (46.3) U for the placebo group (P < 0.01). Differences between the treatment groups did not achieve statistical significance at the final visit for speed of memory, power of attention, or continuity of attention across the first four tests.Fig. 3
