Clinical Trial Summary

The purpose of this study is to compare two different preparations of an antibiotic called cephalexin in capsules to determine if they are essentially the same. The study has two periods. Participants will receive one preparation of cephalexin in each period. At least 7 hours will pass between the study periods. The study is expected to last about 2 days for each participant, not including screening or follow-up.

• Participants who have received any medication, including vitamins (with or without medical prescription) or herbal-based remedies 30 days (or 7 half-lives) prior to the beginning of the study.

• Participants who have been hospitalized for any condition within six months to the beginning of the study.

• Participants who have received investigational drugs within the 60 days prior to the study.
