Abstract:
Background: Insomnia, as one of the most common sleep disorders, is a significant health problem, especially among patients suffering from drug-resistant depression. Problems related to the quality of sleep in that population can significantly affect the effectiveness of treatment and quality of life, which is why it is necessary to search for effective therapeutic interventions in this area. Objective: The aim of this study was to compare the effectiveness of esketamine and other standard antidepressants in improving sleep quality in patients with drug-resistant depression. The main research question is whether and to what extent esketamine improves sleep parameters compared with other antidepressants. Methods: This study involves the analysis of data collected from 50 patients divided into two groups: those using esketamine in combination with other antidepressants and those using other antidepressants. The analysis of the results focuses on the assessment of differences in AIS scores between the groups assessed using the Athens Insomnia Scale (AIS). Results: Insomnia occurs much less frequently among people using esketamine than among people not using this drug. With the increase in the time of using esketamine and with the increase in the dose, the level of insomnia decreases. Conclusions: Esketamine brings about a rapid improvement in sleep quality, which is a significant advance in the treatment of drug-resistant depression. The obtained results not only confirm the effectiveness of esketamine but also show its advantage over traditional treatment methods in improving sleep quality.

Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...

Sedatives and Hypnotics: Overview
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...
