Recruitment & Eligibility

Status: COMPLETED

Sex: Male

Target Recruitment: 20

Inclusion Criteria

All subjects selected for this study will be male non-smokers at least 18 years of age. Subjects will have a BMI (body mass index) of 30 or less.
Each subject shall be given a general physical examination within 28 days of initiation of the study. Such examination includes, but is not limited to, blood pressure, general observations, and history.

Adequate blood and urine samples should be obtained within 28 days before beginning of the first period and at the end of the trial for clinical laboratory measurements.

Clinical laboratory measurements will include the following:

Hematology: hemoglobin, hematocrit, red blood cell count, platelet count, white blood cell count (with differential).
Clinical Chemistry: creatinine, BUN, glucose, SGOT/AST, SGPT/ALT, bilirubin, and alkaline phosphatase.
Urine Analysis: pH, specific gravity, protein, glucose, ketones, bilirubin, occult blood, and cells.
HIV Screen: pre-study
Hepatitis B, C Screen: pre-study
Drugs of Abuse Screen: pre-study and at each check-in Subjects will be selected if all above are normal. Electrocardiograms of all participating subjects will be recorded before initiation of the study and filed with each subject's case report forms.

Exclusion Criteria

Subjects with a history of chronic alcohol consumption (during past 2 years), drug addiction, or serious gastrointestinal, renal, hepatic or cardiovascular disease, tuberculosis, epilepsy, asthma (during past 5 years), diabetes, psychosis or glaucoma will not be eligible for this study.
Subjects whose clinical laboratory test values are greater than 20% outside the normal range on retesting, the subject will not be significant.
Subjects who have a history of allergic responses to the class of drug being tested should be excluded from the study.
All subjects will have urine samples assayed for the presence of drugs of abuse as part of the clinical laboratory screening procedures and at each study period check-in. subjects found to have urine concentrations of any of the tested drugs will not be allowed to participate.
Subjects should not have donated blood and/or plasma for at least thirty (30) days prior to the first dosing of the study.
Subjects who have taken any investigational drug within thirty (30) days prior to the first dosing of the study will not be allowed to participate.
Subjects who do not tolerate venipuncture will not be allowed to participate.
Subjects who use tobacco in any form will not be eligible to participate in the study. Three months abstinence is require.
