Brief Summary
A single dose, two treatments (two cephalexin capsules brands), two sequences, cross-over design was used with a washout of 7 days between the two study periods. Treatment groups balanced with the same number of healthy volunteers who were randomly (in two strata: male and female) assigned to the study drug administration sequences.
