Comparative assessment of the absorption of a generic formulation of 50 mg quetiapine prolonged release tablet against the innovator 50 mg quetiapine tablet conducted under fasting conditions in healthy male and female volunteers.
- Conditions
- Bioequivalence study conducted in healthy volunteers comparing two formulations of quetiapine with no health condition or problem studied. Although this study is being conducted in healthy volunteers who are not being treated for the condition to which the medicine is used, quetiapine belongs to a class of medicines called an atypical antipsychotic drug and is prescribed for the maintenance treatment of Bipolar and schizophrenia.Bioequivalence study conducted in healthy volunteers comparing two formulations of quetiapine with no health condition or problem studied.Although this study is being conducted in healthy volunteers who are not being treated for the condition to which the medicine is used, quetiapine belongs to a class of medicines called an atypical antipsychotic drug and is prescribed for the maintenance treatment of Bipolar and schizophrenia.Other - Research that is not of generic health relevance and not applicable to specific health categories listed above

- Not specified
- Primary Outcome Measures
Name Time Method To compare the bioavailability of quetiapine (as summarised by Cmax and AUC) for the two formulations. All plasma samples will be assayed for quetiapine using a fully validated LC/MS/MS method. Validation will be conducted to comply with EU and FDA guidelines. [0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, 6.5, 7.0, 7.5, 8.0, 9.0, 10.0, 12.0, 16.0, 20.0, 24.0, 32.0 and 48.0 hours ]
- Secondary Outcome Measures
Name Time Method Time to maximum peak concentration (Tmax) and the elimination half life (t1/2). Tmax will be the time where the maximum concentration occurred in the sample points. T1/2 = 0.693/Kel where kel is the terminal elimination rate constant. [0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, 6.5, 7.0, 7.5, 8.0, 9.0, 10.0, 12.0, 16.0, 20.0, 24.0, 32.0 and 48.0 hours ]
