Pharmacokinetics of 3 Formulations of Ibuprofen Suppositories
October 4, 2011 updated by: Johnson & Johnson Consumer and Personal Products Worldwide
A Single-dose, Randomised, Crossover Study to Compare the Rate and Extent of Absorption of Three Formulations of Ibuprofen in Healthy, Fasting Male and Female Volunteers
The purpose of this study is to compare the pharmacokinetic and bioavailability characteristics of two test formulations of ibuprofen for rectal administration with the profile of a marketed reference formulation of ibuprofen 200 mg (for oral administration).
Study Overview
Detailed Description
Ibuprofen is a widely used analgesic and antipyretic in adults and children.
Two ibuprofen suppository formulations have been developed for pediatric use to facilitate dosing in younger age groups.
This is a single-dose, balanced, randomised, three-period crossover study in healthy male and female adult volunteers.
Each volunteer will receive a single dose of 50 mg ibuprofen as a suppository, a single dose of 200 mg ibuprofen as a suppository and a single oral dose of 200 mg ibuprofen (tablet).
There will be 14 blood samples taken over 12 hours in each study period.
Concentrations in plasma of ibuprofen and its S and R enantiomers will be measured using a validated chromatographic method.
Standard pharmacokinetic parameters will be obtained and bioavailability on the basis of rate and extent of drug absorption will be assessed.
