    Summary

    Administering trazodone once nightly improved sleep and reduced daytime fatigue in depressed patients more effectively than divided doses. This single nightly dose offers early psychological benefits for treatment initiation.

    Area of Science:

    • Psychiatry
    • Clinical Pharmacology

    Background:

    • Depression significantly impacts sleep quality and daytime functioning.
    • Optimizing trazodone administration may enhance patient outcomes.

    Purpose of the Study:

    • To compare the efficacy of trazodone administered as divided doses versus a single nightly dose.
    • To evaluate the impact of trazodone dosing regimens on depressive symptoms, sleep, and daytime function.

    Main Methods:

    • A 6-week, double-blind, randomized trial involving 146 depressed patients.
    • Patients received 100-150 mg of trazodone daily, either divided twice daily or as a single nightly dose.
    • Assessment included Hamilton Depression Rating Scale, visual analogue scales, and sleep questionnaires.

    Main Results:

    • Both dosing regimens significantly reduced depression scores (Hamilton Depression Rating Scale).
    • Single nightly trazodone improved daytime fatigue more significantly in the first two weeks.
    • Trazodone improved sleep quality in both groups, with a significantly greater early effect observed with the single nightly dose.

    Conclusions:

    • Trazodone is effective in treating depression regardless of dosing schedule.
    • A single nightly dose of trazodone may offer advantages in improving sleep and reducing daytime fatigue early in treatment.
    • The early sleep improvement with nightly dosing can provide psychological encouragement for depressed patients.
