Can two bronchitis drugs be taken together safely?
NCT ID NCT07797621
First seen Sep 01, 2026 · Last updated Sep 02, 2026 · Updated 1 time
Summary
This early-stage trial tests two experimental drugs, AG2203L and AG2203E, in healthy adults to see if they are safe when taken together and whether they affect each other. Participants receive each drug alone and then both together in a random order. The goal is to measure how the drugs move through the body and to check for any harmful interactions before the drugs are studied in people with acute bronchitis.
