Primary purpose: BASIC_SCIENCE

Brief summary: The purpose of this study is to compare two different preparations of an antibiotic called cephalexin 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.


Eligibility criteria: Inclusion Criteria:

* Participation will be voluntary.
* The body mass index of participants should be between 18-27.
* Participants should have a good health status.
* Limits of variation allowed within normal values at screening will be: blood pressure (seated) up to 139 millimeters of mercury (mm Hg), for systolic, and up to 89 mm Hg for diastolic; heart rate between 60 and 100 beats per minute, and respiratory rate between 14 and 20 breaths per minute.
* Hepatitis B and C and human immunodeficiency virus (HIV) negative.
* Drug abuse or alcohol detection test approximately 12 hours before administering the study medication.

* Participants who have been exposed to medications known as hepatic enzyme inducers or inhibitors or who have been taking potentially toxic medications within the 30 days prior.
* 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.
* Participants allergic to any medication, food, or substance.
* Participants who require therapy with nephrotoxic drugs.
* Participants who have donated 450 mL of blood or more within the 60 days prior to the beginning of the study.
* Participants with history of drug and alcohol abuse.
* Participants with special diet requirement for any cause.
