Study Evaluating Ibuprofen 600 mg Extended Release (ER) For Dental Pain
February 22, 2018 updated by: Pfizer
Ibuprofen 600 Mg Extended Release (er) Single-dose Dental Pain Study
The purpose of this study is to assess the efficacy and safety of a single dose of an ibuprofen 600 mg extended release formulation in post-operative dental pain.
There is concern that the manufacturing process may affect the performance characteristics of the selected prototype.
Therefore, two formulations of this prototype manufactured by two different processes, [roller compaction] and [wet granulation] will be included in this study.
The preferred prototype manufactured by two different methods will be compared to placebo and each other.
This study will also characterize the pharmacokinetic/pharmacodynamic relationship with these formulations.
