The first aim of the present study was to evaluate the bioavailability of ibuprofen dispersed in a novel soft chewable formulation compared with a traditional ibuprofen tablet; its second was to map the quality of taste masking and patient product satisfaction. In a phase 1, single-center, open-label, randomized, crossover study, healthy subjects received a soft-chew formulation or a hard tablet (reference), both containing 100 mg ibuprofen. Serial blood samples were collected over 24 hours to assess ibuprofen bioavailability. Taste and satisfaction after chewing the novel formulation 3 or 8 times were evaluated with a questionnaire. The soft-chew formulation showed comparable bioavailability to the reference tablet. The highest peak plasma concentration was observed after 3 chews, and the relative bioavailability was approximately 8% higher compared to 8 chews. The overall flavor was well appreciated, and chewing 3 times was significantly preferred (P = .043) over chewing 8 times. Soft chewable drug formulations may improve compliance and potentially benefit several subpopulations who experience dysphagia.
