Summary

This study looks at whether taking the blood pressure drug losartan changes how the antibiotic cephalexin works in the body. Twelve healthy volunteers will take both drugs at the same time, three hours apart, or cephalexin alone. Researchers will measure drug levels in blood and urine to see if timing matters.
