Summary
This study looked at whether sodium lauryl sulfate (SLS), a common additive in many medications, changes how the body absorbs the allergy drug fexofenadine. Twelve healthy adults took fexofenadine alone or with low or high amounts of SLS. Researchers measured drug levels in the blood and stool to see if SLS affects absorption. The goal is to understand how inactive ingredients can impact drug effectiveness.
