NCT ID NCT06284902
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested a new version of the allergy drug fexofenadine (Allegra) to see if it is absorbed well when taken with or without water. 25 healthy adults each received six different treatments in random order. The goal was to compare the new tablet to the standard coated tablet. Results will show if the new formulation works similarly, potentially offering more flexibility in how the medication is taken.
