Detailed Description:

This was a single center, randomized, single-dose, open-label, 2 - way crossover bioequivalence study to compare the rate and extent of absorption of a test amoxicillin - clavulanic acid versus Augmentin ES - 600, a reference amoxicillin - clavulanic acid, under fasting condition. Prior to study commencement, subjects were randomly assigned to a treatment in accordance with the randomization scheme generated by Anapharm. Subjects were confined to the Anapharm Clinical Research Facility from at least 10 hours prior to the drug administration until after the 12 - hour post dose blood draw, in each period. The treatment phases were separated by a washout period of 20 days.

A total of 55 healthy, adult subjects signed the study - specific Informed Consent Form and were confined for Period I; of these subjects, 48 (24 males and 24 females) were enrolled and were dosed in the study; 42 of these enrolled subjects completed the study.

    1. Clinically significant illness or surgery within 4 weeks prior to dosing
    2. Any clinically significant abnormality or abnormal laboratory test results found during medical screening
    3. Any reason which, in the opinion of the Clinical Sub - Investigator, would prevent the subjects from participating in the study
    4. Positive test for hepatitis B, hepatitis C or HIV at screening
    5. ECG abnormalities (clinically significant) or vital sign abnormalities (systolic blood pressure lower than 90 or over 140 mmHg, diastolic blood pressure lower than 50 or over 90 mmHg, or heart rate less than 50 or over 100 bpm) at screening
    6. History of significant alcohol abuse or drug abuse within one year prior to the screening
    7. Regular use of alcohol within six months prior to the screening visit (more than fourteen units of alcohol per week [ 1 unit = 150 mL of wine, 360 mL of beer, 0r 45 mL of 40% alcohol])
    8. Use of soft drugs (such as marijuana) within 3 months prior to the screening visit or hard drugs (such as cocaine, phencyclidine [PCP] and crack) within 1 year prior to the screening visit or positive urine drug screen at screening
    9. History of allergic reactions to amoxicillin - clavulanic acid, penicillin, or other related drugs
    10. Use of any drugs known to induce or inhibit hepatic drug metabolism (examples of inducers: barbiturates, carbamazepine, phenytoin, glucocorticoids, Omeprazole; examples of inhibitors: antidepressants (SSRI), cimetidine, diltiazem, macrolides, imidazoles, neuroleptics, verapamil, fluoroquinolines, antihistamines) within 30 days prior to administration of the study medication
    11. Use of an investigational drug or participation in an investigational study within 30 days prior to dosing
    12. Clinically significant history or presence of any gastrointestinal pathology (e.g.: chronic diarrhea, inflammatory bowel diseases), unresolved gastrointestinal symptoms (e.g.: diarrhea, vomiting) liver or kidney disease, or other conditions known to interfere with the absorption, distribution, metabolism or excretion of the drug.
    13. Any clinically significant history or presence of neurological, endocrinal, cardiovascular, pulmonary, hematological, immunologic, psychiatric, or metabolic disease
    14. Use of the prescription medication within 14 days prior to the administration of study medication or over - the - counter products (including natural food supplements, vitamins, garlic as a supplement) within 7 days prior to the administration of the study medication, except for topical products without systemic absorption and hormonal contraceptives
    15. Difficulty to swallow the study medication
    16. Smoking more than 25 cigarettes per days
    17. Any food allergy, intolerance, restriction or special diet that, in the opinion of the Clinical Sub-Investigator, could contraindicate the subject's participation in this study
