  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Criteria

Inclusion Criteria:

  1. Screening Demographics: All volunteers selected for this study will be healthy men and women 18 years of age or older at the time of dosing. The weight range will not exceed ± 20% for height and body frame as per Desirable Weights for Adults -1983 Metropolitan Height and Weight Table.
  2. Screening Procedures: Each volunteer will complete the screening process within 28 days prior to Period I dosing. Consent documents for both the screening evaluation and HIV antibody determination will be reviewed, discussed, and signed by each potential participant before full implementation of screening procedures.

    Screening will include general observations, physical examination, demographics, medical and medication history, an electrocardiogram, sitting blood pressure and heart rate, respiratory rate and temperature. -The physical examination will include, but may not be limited to, an evaluation of the cardiovascular, gastrointestinal, respiratory and central nervous systems.

    The screening clinical laboratory procedures will include:

    • HEMATOLOGY: hematocrit, hemoglobin, WBC count with differential; RBC count, platelet count;
    • CLINICAL CHEMISTRY: serum creatinine, BUN, glucose, AST(GOT), ALT(GPT), albumin, total bilirubin, total protein, and alkaline phosphatase;
    • HIV antibody and hepatitis B surface antigen screens;
    • URINALYSIS: by dipstick, microscopic examination if dipstick positive; and .
    • URINE DRUG SCREEN: ethyl alcohol, amphetamines, barbiturates, benzodiazepines, cannabinoids, cocaine metabolites, opiates and phencyclidine.
    • SERUM PREGNANCY SCREEN (female volunteers only)
  3. If female and:

    • of childbearing potential, is practicing an acceptable barrier method of birth control for the duration of the study as judged by the investigator(s), such as condoms, sponge, foams, jellies, diaphragm; intrauterine device (IUD), or abstinence; or
    • is postmenopausal for at least I year; or
    • is surgically sterile (bilateral tubal ligation, bilateral oophorectomy, or hysterectomy).

Exclusion Criteria:

  1. Volunteers with a recent history of drug or alcohol addiction or abuse.
  2. Volunteers with the presence of a clinically significant disorder involving the cardiovascular, respiratory, renal, gastrointestinal, immunologic, hematologic, endocrine, or neurologic system(s) or psychiatric disease (as determined by the medical investigator).
  3. Volunteers whose clinical laboratory test values are outside the accepted reference range and when confirmed on re-examination are deemed to be clinically significant.
  4. Volunteers demonstrating a positive hepatitis B surface antigen screen or a reactive HIV antibody screen.
  5. Volunteers demonstrating a positive drug abuse screen when screened for this study.
  6. Female volunteers demonstrating a positive pregnancy screen.
  7. Female volunteers who are currently breastfeeding.
  8. Volunteers with a history of allergic response(s) to metformin or related drugs.
  9. Volunteers with a history of clinically significant allergies including drug allergies.
  10. Volunteers with a clinically significant illness during the 4 weeks prior to Period I dosing (as determined by the medical investigator).
  11. Volunteers who currently use tobacco products.
  12. Volunteers who have taken any drug known to induce or inhibit hepatic• drug metabolism in the 30 days prior to Period I dosing.
  13. Volunteers who report donating greater than 150 mL of blood within 30 days prior to Period I dosing. All subjects will be advised not to donate blood for four weeks after completing the study.
  14. Volunteers who have donated plasma (e.g. plasmapheresis) within 14 days prior to Period I dosing. All subjects will be advised not to donate plasma for four weeks after completing the study.
  15. Volunteers who report receiving any investigational drug within 30 days prior to Period I dosing.
  16. Volunteers who report taking any systemic prescription medication in the 14 days prior to Period I dosing.
