Detailed Description:

The study was conducted as an open label, balanced, randomised, two-treatment, two-period, two-sequence, single-dose, crossover , bioequivalence study on Doxycycline monohydrate comparing Doxycycline monohydrate 100mg tablets of Ranbaxy Pharmaceuticals Inc with Adoxa ® 100 mg tablets of Bradley Pharmaceuticals Inc. in healthy, adult, human, subjects under fed conditions.

A total of 32 non-smoking subjects (21 men and 11 women) were included in this study, of which 32 finished the study according to the protocol.

Exclusion Criteria:

  • a) Hypersensitivity to Doxycycline monohydrate (Adoxa®), or related compounds such as tetracycline.

    b) Any history of a clinical condition which might affect drug absorption, metabolism or passage of drugs out of the body, e.g. sprue, celiac disease, Crohn's disease, colitis, liver, kidney or thyroid conditions.

    c) Recent history of mental illness, drug addiction, drug abuse or alcoholism. d) Donation of greater than 500 ml of blood in the past 4 weeks prior to study dosing or difficulty in donating blood.

    e) Received an investigational drug within the 4 weeks prior to study dosing. f) Currently taking any systemic prescription medication, except oral / cutaneous/ vaginal hormone contraceptives, within the 7 days prior to study dosing or over-the-counter medication within 3 days of study dosing. This prohibition does not include vitamins or herbal preparations taken as nutritional supplements for non-therapeutic indications as judged by the attending physician. Any non-prescription medication consumption reported will be reviewed by the investigator prior to dosing. At the discretion of the investigator these volunteers may be enrolled if the medication is not anticipated to alter study integrity.

    g) Regular smoking of more than 5 cigarettes per week or the daily use of nicotine-containing products beginning 3 months before the study medication administration through the final evaluation.

    h) If female, the subject is lactating or has a positive pregnancy test at screening and prior to each of the two treatment periods.
