A Study of Cephalexin Capsules in Healthy Participants

Phase 1

Completed

Conditions: Healthy Volunteers

Interventions: Drug: Cephalexin

Registration Number: NCT02123446

Lead Sponsor: Eli Lilly and Company

Brief 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.
