New marker could numb skin in minutes, study says
NCT ID NCT07273916
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This Phase 2 trial tests a topical anesthetic marker applied to the skin to reduce pain from needle pricks. Twenty adults will have the marker applied to their forearm, and pain will be measured every 10 minutes for 40 minutes compared to untreated skin. The goal is to see how well and how fast it works.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- topical anesthetic marker (lidocaine, tetracaine, Transcutol P, and dye)
- What this could lead to
- If it works, this could provide a quick, easy-to-use topical anesthetic for minor procedures like injections or blood draws.
- What could go wrong
- This is a small, early-phase trial with only 20 people, testing pain from light pricks on the forearm—not real medical procedures. The effect may not translate to clinical settings.
