Addressing Sleep Disorders in Psychiatry: Comparing the Use of Melatonin, Trazodone, and Doxepin.

Introduction Sleep disorders are prevalent among psychiatric patients, and pharmacological treatments such as melatonin, trazodone, and doxepin are commonly prescribed. This study aimed to assess the efficacy and acceptability of these three medications in improving sleep quality and reducing daytime drowsiness in psychiatric patients. Methodology A total of 175 psychiatric patients with sleep disturbances participated in this cohort study at the Abbas Institute of Medical Sciences, Muzaffarabad, Pakistan.Participants were initially randomized, with assignments subsequently reviewed and confirmed by physicians based on clinical considerations, into one of three therapy groups: doxepin, trazodone, or melatonin. They were monitored over the course of six months, from February to July 2024. The Pittsburgh Sleep Quality Index (PSQI) was used to measure sleep quality, the Epworth Drowsiness Scale (ESS) was used to measure daytime drowsiness, and the Clinical Global Impression-Improvement (CGI-I) scale was used to determine clinical improvement. Pre- and post-treatment data were analyzed in IBM SPSS Statistics for Windows, Version 26.0 (Released 2019; IBM Corp., Armonk, New York, United States) using statistical techniques such as paired t-tests, ANOVA, and chi-square tests. Results Trazodone, doxepin, and melatonin were evaluated for their effectiveness and tolerability in improving sleep quality and reducing daytime drowsiness among 175 psychiatric patients (n=58 for melatonin, n=59 for trazodone, n=58 for doxepin). Trazodone showed the greatest improvement in sleep quality, with significant reductions in PSQI scores at six months (mean decrease = 7.0, SD = 1.9) and the highest CGI-I improvement rates (n=59, 76%, p = 0.02), but it was associated with frequent adverse effects, including morning grogginess (n=59, 15%, p = 0.03) and orthostatic hypotension (n=59, 10%, p = 0.02). Doxepin significantly enhanced sleep continuity (PSQI reduction = 6.8, SD = 2.1) and had a better tolerability profile than trazodone but was linked to dry mouth (n=58, 13%, p = 0.04). Melatonin, while slightly less effective in improving sleep quality (PSQI reduction = 6.1, SD = 2.0), had the fewest adverse effects, including the lowest rates of morning grogginess (n=58, 5%, p = 0.03) and dizziness (n=58, 10%, p = 0.41), and significantly reduced daytime drowsiness (ESS decrease = 3.9, SD = 1.7, p = 0.04). These findings highlight trazodone and doxepin as the most effective treatments, while melatonin offers better tolerability for patients concerned about adverse effects. Conclusion In psychiatric patients, trazodone was the most successful medication for enhancing sleep quality; however, other groups cannot use it due to its adverse effects. For patients who were more likely to have side effects, melatonin was a safer option, but doxepin offered a good balance between effectiveness and tolerability.
