Brief summary

The objective of this study is to evaluate the bioequivalence of the test (new) formulation of 800 mg ibuprofen sustained release tablet relative to that of the reference formulation (innovator brand of 800 mg ibuprofen sustained release tablet) following oral administration of a multiple dose of 800 mg in healthy male and female subjects under fasting conditions and at steady state.

Interventions

Multiple dose, crossover over study design whereby each participant receives the test formulation of ibuprofen (1 x 800 mg) on five occasions and the innovator formulation of ibuprofen (1 x 800 mg) on five occasions with each dose seperated by a 10 day washout period. The intervention for this trial is the test formulation of ibuprofen. On study days 1-5 subjects will receive 5 daily doses of one formulation (either the test or innovator) and on study days 15-19 they will receive 5 daily doses

Multiple dose, crossover over study design whereby each participant receives the test formulation of ibuprofen (1 x 800 mg) on five occasions and the innovator formulation of ibuprofen (1 x 800 mg) on five occasions with each dose seperated by a 10 day washout period. The intervention for this trial is the test formulation of ibuprofen. On study days 1-5 subjects will receive 5 daily doses of one formulation (either the test or innovator) and on study days 15-19 they will receive 5 daily doses of the other formulation (either the innovator or test). 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. Participants are required not to eat for 10 hours before receiving each dose. On study days 1 to 4 and 15 to 18 subjects will report to Zenith Technology for dosing and the provision of one blood sample. They will then be given a light breakfast to consume following each dose at home. On study day 5 and 19 no water is allowed for 1 hour prior to dosing until 1 hour after dosing (except for the water consumed with the dose) and are required 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 can be monitored and for 24 hours after dosing.
