- Primary Outcome Measures
Name Time Method To compare the bioavailability of metformin (as summarised by Cmax and AUC) for the formulation. All plasma samples will be assayed for metformin using one fully validated LC/MS/MS method. Validation will be conducted to comply with EU and FDA guidelines.[0, 0.5, 1.0, 2.0, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, 6.5, 7.0, 7.5, 8.0, 8.5, 9.0, 10.0, 11.0, 12.0, 13.0, 14.0, 15.0, 16.0, 20.0, 24.0, 26.0 and 32.0 hours]
- Secondary Outcome Measures
Name Time Method Time to maximum peak concentration (Tmax) will be determined by plasma sample analysis. Tmax will be the time where the maximum concentration occurred in the sample points.[0, 0.5, 1.0, 2.0, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, 6.5, 7.0, 7.5, 8.0, 8.5, 9.0, 10.0, 11.0, 12.0, 13.0, 14.0, 15.0, 16.0, 20.0, 24.0, 26.0 and 32.0 hours]
