Nasal spray painkiller: can a higher dose work better in the ER?
NCT ID NCT07816302
First seen Sep 11, 2026 · Last updated Sep 17, 2026 · Updated 2 times
Summary
Researchers are testing whether a 30 mg dose of ketorolac given as a nasal spray relieves acute pain as well as a 20 mg dose in adults who arrive at the emergency department with moderate to severe pain. The trial enrolls 100 people aged 18 to 65 who weigh more than 50 kg and have had pain for less than 48 hours. Participants receive one of the two doses through a mucosal atomizer, and researchers measure pain scores at 15, 30, and 45 minutes to compare effectiveness and side effects.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ketorolac, a nonsteroidal anti-inflammatory drug (NSAID), given as a nasal spray
- What this could lead to
- If the higher dose works as well as the lower dose, emergency departments could use a simple nasal spray to relieve acute pain without an IV line.
- What could go wrong
- This is a small, single-center trial of 100 people, so the results may not apply to everyone. Ketorolac can cause stomach bleeding, kidney problems, and allergic reactions, and it is not safe for people with ulcers, kidney failure, or NSAID allergies.
