Summary

This trial tests whether high-frequency repetitive transcranial magnetic stimulation (rTMS) can reduce cravings, drug use, and withdrawal symptoms in adults addicted to etomidate. Forty participants will receive either active rTMS or a sham (fake) treatment over 20 sessions in 4 weeks. Researchers will track changes in drug use, cravings, mood, and decision-making for up to 6 months to see if the brain stimulation offers a lasting benefit.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: high-frequency repetitive transcranial magnetic stimulation (rTMS) delivered to the dorsolateral prefrontal cortex
What this could lead to: If it works, this could point toward a non-drug treatment for etomidate addiction, helping people reduce cravings and drug use.
What could go wrong: This is a small early trial with only 40 participants, so results may not apply widely. The sham procedure may also produce some effects, making it harder to see a clear benefit.
