Brief summary: The objective of this study was to investigate the bioequivalence of Genpharm's clarithromycin tablets following a single, oral 500 mg (1 x 500 mg) dose compared to the Biaxin® filmtab® (Abbott Laboratories USA) administered under fed conditions. Forty-four (44) healthy, light-, non- or ex-smoking subjects of at least 18 a years of age were randomized, in this two-period, two-treatment crossover bioequivalence study conducted by Eric Sicard, M.D. at Algorithme Pharma Inc. Montreal, Canada.

Statistical analysis of the data reveals that 90% confidence intervals are within the acceptable bioequivalent range of 80% and 125% for the natural log transformed parameters AUCT, AUCI and Cmax. This study demonstrates that Genpharm's clarithromycin 500 mg tablets are bioequivalent to Biaxin® filmtab® 500 mg tablets (Abbott Laboratories USA) administered under fed conditions.


Eligibility criteria: Inclusion Criteria:

Healthy according to the laboratory results and physical examination

Exclusion Criteria:

Severe hypersensitivity reactions (like angioedema) to any drugs

Presence or history of significant gastrointestinal, liver or kidney disease, or any other conditions known to interfere with the absorption, distribution, metabolism or excretion of drugs or known to potentiate or predispose to undesired effects

Presence or history of significant cardiovascular, pulmonary, hematologic, neurologic, psychiatric, endocrine, immunologic or dermatologic disease

Females who are pregnant, lactating or are likely to become pregnant during the study periods.

Females of childbearing potential who refuse to use an acceptable contraceptive regimen throughout the study.

Positive pregnancy test before or during the study.

Use of the following products (astemizole, terfenadine, cisapride or pimozide) in the previous 14 days before day 1 of the study

Maintenance therapy with any drug, or significant history of drug dependency, alcohol abuse (\> 3 units of alcohol per day, intake of excessive alcohol, acute or chronic), or serious psychological disease

Any clinically significant illness in the previous 28 days before day 1 of this study

Use of enzyme-modifying drugs in the previous 28 days before day 1 of this study (all barbiturates, corticosteroids, phenylhydantoins, etc.)

Participation in another clinical trial in the previous 28 days before day 1 of this study

Donation of 500 mL or more of blood (Canadian Blood Services, Hema-Quebec, clinical studies, etc.) in the previous 56 days before day 1 of this study

Positive urine screening of drugs of abuse (drug names are presented in section 7.1.4)

Positive results to HIV, HBsAg or anti-HCV tests

History of fainting upon blood sampling
