Can an aspirin injection work faster than a pill?
NCT ID NCT05166096
First seen Aug 12, 2026 · Last updated Aug 13, 2026 · Updated 1 time
Summary
This early-stage trial is testing how aspirin behaves in the body when given as a quick injection into a vein compared with the same dose taken as a pill. Healthy adults aged 18 to 55 will receive both forms on separate occasions, and researchers will measure blood levels, effects on blood clotting, and safety. The goal is to understand the differences between the two delivery methods, which could inform future use of injectable aspirin.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Aspirin given either as an intravenous injection or as an oral tablet
- What this could lead to
- If successful, this could support the development of an intravenous aspirin formulation for faster or more reliable effects in situations where oral aspirin cannot be used.
- What could go wrong
- This is an early-phase study in a small number of healthy volunteers, so results may not apply to patients. The trial is designed to compare the two forms, not to prove any treatment benefit.
