Brief summary
The objective of this study was to investigate the bioequivalence of Genpharm's baclofen tablets following a single, oral 20 mg (1 x 20 mg) dose compared to the Baclofen USP (Watson Laboratories Inc., USA) administered under fasting conditions. Twenty-seven (27) 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 baclofen 20 mg tablets are bioequivalent to Baclofen USP 20 mg tablets (Watson Laboratories Inc., USA) administered under fasting conditions.

Inclusion criteria
Subjects meeting all of the following criteria may be included in the study: Availability of subject for the entire study period and willingness to adhere to protocol requirements as evidenced by the informed consent form duly signed by the subject Males aged from 18 to 55 years with a body mass index (BMI) greater than or equal to 19 and below 30; demographic data (sex, age, ethnic group, body weight, height and smoking habits) will be recorded and reported in the final report Clinical laboratory values within the laboratory's stated normal range; if not within this range, they must be without any clinical significance and must be recorded as such in the CRF (laboratory tests are presented in section 7.1.3) Healthy according to the laboratory results and physical examination Normal cardiovascular function according to ECG Subjects should be light-, non- or ex-smokers
