A network meta-analysis of the long- and short-term efficacy of sleep medicines in adults and older adults

Abstract

Background: This study focuses on seven commonly used hypnotics to comprehensively analyze the effects of long- and short-term use on sleep outcomes among adults and older adults.

Methods: A network meta-analysis was performed. The insomnia medications were classified into seven categories: benzodiazepines, z-drugs, melatonin, H1-antagonists, orexin receptor antagonists (ORAs), antidepressants, and anticonvulsants. We compared their efficacy of total sleep time, sleep latency, sleep efficiency and wake after sleep onset in subgroups short-term, long-term, elderly, and adults.

Results: A total of 111 RCTs involving 25,923 participants were included in this study.

Conclusions: ORAs can be widely used in adults and the elderly, and both short-term and long-term use are effective for primary insomnia. H1-antagonists are more effective in adults than in the elderly. Although benzodiazepines have a more obvious effect on sleep maintenance, it is best to reduce their use due to their side effects, especially for the elderly. As a food supplement, melatonin has little effect on adults, but it still has a certain effect on the elderly.
