    Oral flunitrazepam significantly improved sleep and reduced apprehension in gynecological patients compared to placebo. This new premedicant offers prominent sedative and anxiolytic effects lasting over eight hours.

    Area of Science:

    • Pharmacology
    • Anesthesiology
    • Clinical Medicine

    Background:

    • Preoperative anxiety and poor sleep can negatively impact surgical outcomes.
    • Effective premedicants are crucial for patient comfort and a smooth perioperative experience.

    Purpose of the Study:

    • To evaluate the clinical efficacy of oral flunitrazepam as a premedicant in gynecological surgery.
    • To correlate plasma concentrations of flunitrazepam with its clinical effects.

    Main Methods:

    • A double-blind, placebo-controlled study involving 81 gynecological patients.
    • Patients received either oral flunitrazepam (2 mg night before, 2 mg morning of surgery) or placebo.
    • Clinical effects were assessed subjectively and objectively; plasma drug concentrations were measured via gas chromatography.

    Main Results:

    • Flunitrazepam significantly improved sleep and reduced apprehension compared to placebo.
    • Patients receiving flunitrazepam reported increased dizziness, but no significant differences were observed in emetic effects or blood pressure.
    • No correlation was found between plasma drug concentrations and clinical outcomes.

    Conclusions:

    • Oral flunitrazepam demonstrates significant sedative and anxiolytic properties, making it an effective premedicant.
    • The beneficial effects of flunitrazepam premedication persist for at least 8 hours post-administration.
    • Further research may explore optimal dosing and patient selection for flunitrazepam use.
