Research findings on gabapentin’s effects on REM sleep have yielded mixed results, highlighting the complexity of sleep pharmacology. Some studies have reported a reduction in REM sleep duration in patients taking gabapentin, while others have found no significant changes. Gabapentin and REM Sleep: Effects, Benefits, and Potential Risks is a topic of particular interest to researchers. Some studies have found that gabapentin may increase slow-wave sleep, also known as deep sleep, which is crucial for physical restoration and cognitive function. A recent review of the mechanistically similar medication, pregabalin, on sleep disturbances across multiple pain-related clinical conditions suggests that it has a direct effect on sleep (independent of its pain-relieving properties). 39 Likewise, although fewer studies were described, a similar conclusion was drawn for gabapentin. 39 Thus Gabapentin was associated with significantly higher values of KSD Sleep Quality Index and reported TST versus placebo; no other reported outcomes were significant. Neither gabapentin dose produced evidence of next-day residual effects as measured by DSST and SSS. Adverse events were infrequent (< 5%). Gabapentin and sleep. Most studies show that gabapentin improves slow wave sleep (“deep sleep”) and total sleep time. Two small studies showed that gabapentin may help people with primary insomnia and occasional sleep disturbance improve total sleep time and wakefulness in the morning. Summary: Purpose: The older antiepileptic drugs (AEDs) have a variety of effects on sleep, including marked reduction in rapid-eye-movement (REM) sleep, slow-wave sleep (SWS), and sleep latency, and an increase in light sleep. The effects of the newer AEDs on sleep are unknown. Our purpose was to study the effect of gabapentin (GBP) on sleep. Newer drugs are being developed that have been shown to enhance NREM, specifically slow wave sleep, as well as REM sleep. The purpose of this chapter is to review and discuss the clinical relevance and functional significance of drug-related sleep stage effects. Normal Sleep Staging Preliminary evidence indicates that gabapentin can attenuate insomnia, bolster sleep quality, and increase total sleep duration. Moreover, gabapentin has been shown to increase slow-wave sleep (SWS), promote sleep maintenance, and decrease unwanted awakenings throughout the night. Purpose: The older antiepileptic drugs (AEDs) have a variety of effects on sleep, including marked reduction in rapid-eye-movement (REM) sleep, slow-wave sleep (SWS), and sleep latency, and an increase in light sleep. The effects of the newer AEDs on sleep are unknown. However, gabapentin can also alter REM sleep patterns, with some research indicating a reduction in REM sleep duration. The impact of Gabapentin and REM Sleep: Effects, Benefits, and Potential Risks is an area of ongoing investigation, as changes in REM sleep can affect various aspects of cognitive function and emotional processing. When it Time spent in REM sleep by PTZ-treated animals under gabapentin effect. A significant increment in REM sleep is observed after gabapentin administration (*p < 0.05). The additional increment related to gabapentin dose was not significant. Compared with the placebo group, the gabapentin group showed significant improvement in sleep quality (P < 0.001), next-day functioning (P < 0.001), number of nighttime awakenings caused by RLS symptoms (P = 0.043), and number of hours awake due to RLS symptoms (P = 0.019) after 12 weeks of treatment; the gabapentin group had a significantly Bupropion is a low-strength dopamine–norepinephrine reuptake inhibitor, and its effect on REM sleep is debated: some argue no effect , and others an increase . Often used as an adjuvant to SSRIs because it thwarts some of their side effects, it induces very few episodes of RBD and increases dream recall frequency (90, 91). Unlike some traditional sleep medications that can suppress REM sleep, gabapentin appears to have a more balanced effect on sleep architecture, potentially preserving the natural progression through sleep stages. Daytime and nocturnal seizures fragment sleep, reducing the percentage of rapid-eye-movement (REM) sleep and slow-wave sleep (SWS) (1,2). Many of the older AEDs reduce the percentage of REM and SWS and increase arousals, awakenings, and stage shifts, suggesting a ten-dency for sleep fragmentation. Gabapentin is considered highly effective for the treatment of insomnia for a few reasons. First and foremost, it improves sleep quality by reducing spontaneous arousal in the brain. It also increases total sleep time thanks to fewer awakenings and its ability to help individuals go to sleep faster.
