Which numbing agent wins for a more comfortable throat scope?
NCT ID NCT07691346
First seen Jul 08, 2026 · Last updated Jul 09, 2026 · Updated 1 time
Summary
This trial compares two common throat-numbing medicines—dyclonine hydrochloride mucilage and tetracaine hydrochloride jelly—to see which one works better for reducing discomfort during an unsedated gastroscopy. About 208 adults scheduled for the procedure will receive one of the two numbing agents before the scope is inserted. The study measures pain, taste, nausea, and how well the medicine clears foam to help doctors choose the best option for patient comfort.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Dyclonine hydrochloride mucilage and tetracaine hydrochloride jelly
- What this could lead to
- If one numbing agent proves better, it could become the standard choice for throat anesthesia during gastroscopy, making the procedure more comfortable for patients.
- What could go wrong
- This is a single-center trial with 208 participants, so results may not apply to all patients. The study compares two existing drugs, so no major breakthrough is expected.
