Summary

Insomnia is a disorder characterized by difficulties in falling asleep, maintaining sleep or waking up too early, and impairment of daytime functioning. Drug-dependent insomnia refers to insomnia patients taking sedatives and sleeping pills regularly for a long period of time, and becoming psychologically and physiologically dependent on them. In many countries, auricular acupressure (AA) has attracted growing attention as a complementary or alternative treatment for insomnia; however, there is a lack of rigorous randomized, controlled studies evaluating AA specifically for estazolam-dependent insomnia. Our proposed trial aims to assess the therapeutic effect of AA on estazolam-dependent insomnia.

Detailed description

This study is a randomized, single-blinded, three-arm controlled trial. No less than 120 participants will be randomized into one of three groups: AA group, sham auricular acupressure (SAA) group, and conventional dosage reduction group. All treatments will be administered for 4 weeks, with a follow-up period of 1 month. The primary clinical outcomes will be estazolam dosing and reduction rates, serum gamma-aminobutyric acid (GABA) and cortisol (CORT) levels. Secondary outcomes will concern the Pittsburgh sleep quality index (PSQI) and Benzodiazepine Withdrawal Symptom Questionnaire (BWSQ). Both intention-to-treat and per-protocol analyses will be performed, with significance level determined as 5%.

Conditions

• Estazolam-dependent Insomnia

Interventions

Type	Name	Description
DRUG	Conventional dosage reduction	The doctor will guide patients to adjust medication dosage once a week in the outpatient clinic. When patients experience withdrawal reactions such as worsening insomnia or anxiety symptoms due to drug reduction, they will be returned to the oral dose before the current reduction, and the dosage will be reduced again after evaluation in the next reduction cycle. The treatment for 4 weeks is one course and 1 course of treatment is required totally.
PROCEDURE	Auricular acupressure	Auricular acupressure is a non-pharmacological therapy that involves applying acupressure on the surface of points in different parts of the ear. One side of the auricular acupoints will be treated first and the tapes will be kept in place for 3 days. On the fourth day, the tapes on the ear will be removed and new tapes will be applied to the opposite side of the ear. The purpose of replacing tapes is to reduce the adverse events (AEs) that may be caused by long-term stimulation unilaterally. In addition, the participants will be informed to press the tapes by themselves for 3 to 5 minutes vertically and appropriately to achieve the sensation, with a duration of 4 to 5 times a day. The treatment will last for 4 weeks, and the follow-up will be done after 1 month.
PROCEDURE	Sham auricular acupressure	Based on the estazolam reduction method in the control group, the acupuncturist will place the same skin-colored adhesive tapes without vaccaria on the auricular points, but these tapes will not be pressed during treatment.
