Comparative assessment of the absorption of a generic formulation of ibuprofen sustained release tablet against the innovator ibuprofen sustained release tablet conducted under fasting conditions in healthy male and female volunteers

INTERVENTION: Single dose, crossover study design whereby each participant receives the test formulation of ibuprofen (1 x 800 mg) on one occasion and the innovator formulation of ibuprofen (1 x 800 mg) on one occasion with each dose seperated by a one week washout period. The intervention for this trial is the test formulation of ibuprofen. No water is allowed for 1 hour prior to dosing until 1 hour after dosing (except for the water consumed with the dose). Participants are required not to eat for 10 hours before receiving each dose and to fast for approximately 4 hours after receiving each dose. Bathroom visits will be supervised to ensure no unauthorised water or food intake and for personal safety. Participants will be confined at the Clinical Site for 10 hours prior to dosing to ensure compliance and will be monitored and for 24 hours after dosing. Standard meals will be consumed at the Clinical Site with no additional food intake allowed. Alcohol breath testing will be performed upon each participant reporting to the Clinical Site 10 hours prior to dosing. Pre and post study laboratory tests will be completed to assess the health of participants along with HIV, Hepatitis and drugs of abuse testing. Each dose (1 x 800 mg) will be taken orally with 240 ml of water at ambient temperature. Medication must be swallowed whole and a mouth check will be conducted to ensure the medication has been taken as directed. CONDITION: Bioequivalence study conducted in healthy volunteers comparing two formulations of Ibuprofen 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, ibuprofen belongs to a class of medicines called an analgesic and anti‐inflammatory. It is used for the treatment of rheumatoid arthritis, ankylosing spondylitis, osteoarthritis and other non‐rheumatoid arthropathies PRIMARY OUTCOME: To compare the bioavailability of ibuprofen (as summarised by Cmax and AUC) for the formulation. All plasma samples will be assayed for ibuprofen using one fully validated LC/MS/MS method. Validation will be conducted to comply with EU and FDA guidelines. SECONDARY OUTCOME: 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. INCLUSION CRITERIA: Healthy male and non‐pregnant females Aged between 18 and 55 Non‐smoker BMI between 18 and 33 inclusive Normal, healthy individuals as determined by medical history, physical examination, ECG, blood pressure and laboratory tests Able to provide written informed consent
