NCT ID NCT07264738
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This pilot study tests whether taking ondansetron, a common anti-nausea drug, before an unsedated throat scope (EGD) can reduce gagging, nausea, and overall discomfort. About 40 Chinese patients who have had this exam before will either receive ondansetron plus a numbing gargle, or just the gargle. After the procedure, they will rate their discomfort and gagging to see if the drug helps.
