This study will compare the relative bioavailability (rate and extent of absorption) of 40 mg Benazepril Hydrochloride Tablets by TEVA Pharmaceuticals Industries, Ltd. with that of 40 mg LOTENSIN® Tablets by Novartis Pharmaceuticals following a single oral dose (1 x 40 mg) in healthy adult volunteers under non-fasting conditions.

Criteria for Evaluation: FDA Bioequivalence Criteria

Statistical Methods: FDA bioequivalence statistical methods

Inclusion Criteria:

• Screening Demographics: All volunteers for selected for this study will be healthy men or women 19 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 Men - 1983 Metropolitan height and Weight Table or as per Desirable Weights for Women - 1983 Metropolitan Height and Weight Table. Subjects must have a minimum weight of at least 110 pounds.
• 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, a 12-lead 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:

  1. Hematology: hematocrit, hemoglobin, WBC count with differential, RBC count, platelet count;
  2. Clinical Chemistry: serum creatinine, BUN, glucose, AST(GOT), ALT(GPT), albumin, total bilirubin, total protein, and alkaline phosphatase;
  3. HIV antibody, hepatitis B surface antigen, and hepatitis C antibody screens;
  4. Urinalysis: by dipstick; full microscopic examination if dipstick positive; and
  5. Urine Drug Screen: ethyl alcohol, amphetamines, barbiturates, benzodiazepines, cannabinoids, cocaine metabolites, opiates and phencyclidine.
  6. Serum Pregnancy Screen (female volunteers only)

• 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.
• 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 weks after completing the study.
