Ultrasound maps gluteal muscle to improve depot injection safety
NCT ID NCT07815587
First seen Sep 11, 2026 · Last updated Sep 11, 2026
Summary
Researchers at St. Olavs Hospital are using ultrasound to measure the gluteal muscle in adults who receive depot antipsychotic injections and in healthy volunteers. The study aims to better understand the anatomy relevant to giving these long-acting injections into the buttocks. By measuring the distance from skin to muscle, the team hopes to identify the best injection site and reduce potential problems.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help doctors choose safer injection sites for depot antipsychotic medications, potentially reducing discomfort or complications.
- What could go wrong
- This is a small observational study with 60 participants, so findings may not apply to everyone. Ultrasound measurements alone may not capture all factors that affect injection safety.
