Bioequivalence Study of Fosinopril 40mg Tablets Under Fasting Conditions

The objective of this study is to compare the relative bioavailability of fosinopril sodium 40 mg tablets (Ranbaxy Laboratories Limited, Lot No. 1238312) with that of Monopril® in healthy adult subjects under fasting conditions.

The study was conducted as an open label, balanced, randomised, two-treatment, two-period, two-sequence, single-dose, crossover , bioequivalence study on Fosinopril formulations comparing fosinopril 40mg tablets of Ranbaxy Laboratories with Monopril® in healthy, adult, human, subjects under fasting conditions

Eligible subjects underwent pre-study examinations that included a physical examination, 12-1cad ECG, and laboratory tests - including hematology, blood chemistries, urinalysis, infectious diseases (Hepatitis B, Hepatitis C, HIV), and urine drugs of abuse. Laboratory testing for female subjects also included a serum pregnancy test.

Forty (40) subjects were enrolled in this study; 39 completed the study.

Eligibility Criteria:
Inclusion Criteria:

* Non-institutionalized subjects consisting of members of the community at large.

Characterization of Study Group

* All subjects selected for this study will be at least 18 years of age.
* Clinical laboratory measurements will include the following:

Hematology:

* hemoglobin, hematocrit,
* red blood cell count,
* platelets, and white blood cell count (with differential).

Clinical Chemistry:

* creatinine, BUN, glucose, SGOT/AST,
* SGPT/ALT, bilimbin, and alkaline phosphatase.

Urine Analysis:

* pH, specific gravity,
* protein, glucose, ketones,
* bilimbin, occult blood, and cells.

HIV Screen:

* (pre-study only) Hepatitis-B, C Screen:
* (pre-study only) Drugs of Abuse Screen:
* pre-study and at check-in each study period

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 may be retested. If the clinical values are outside the range on retesting, the subject will not be eligible to participate in the study unless the clinical investigator deems the result to not be significant.
* Subjects who have a history of allergic responses to the class of drug being tested (including any penicillin product) 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 check-in each study period. 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 drag within thirty (30) days prior to the first dosing of the study will not be allowed to participate.
* Female subjects who are pregnant or who are able (women with child bearing potential) to become pregnant during the study will not be allowed to participate. Female subjects of child bearing potential must either abstain from sexual intercourse or use a reliable barrier method (eg condom, IUD) of contraception during the course of the study (first dosing until last blood collection) or they will not be allowed to participate. Subjects who have used implanted or injected hormonal contraceptives (except Lunelle monthly injection) anytime during the 6 months prior to study dosing, Lunelle monthly injection anytime during the 45-days prior to study dosing or used hormonal contraceptives within 14 days before dosing will not be allowed to participate.
* All female subjects will be screened for pregnancy at check in in each study period. Subjects with positive or inconclusive results will be withdrawn from the study.
