Objectives: A novel, immediate-release tablet formulation of ibuprofen sodium dihydrate, Advil(R) Film-Coated Tablets (IBUNa), has been developed that is absorbed faster than standard IBU tablets. The objective of the current study was to compare the efficacy and onset of analgesia of this new formulation with standard IBU tablets after a single dose.

Methods: Subjects (N=316) with at least moderate baseline postsurgical dental pain were randomized to 400 mg IBUNa, Advil(R) (IBUAdv), Motrin(R) (IBUMot), or placebo. Primary endpoints were time-weighted sum of pain relief and pain intensity differences over 8 hours (SPRID 0-8) and time to onset of meaningful pain relief (TMPR) measured by the double-stopwatch method.

Results: SPRID 0-8 was significantly greater for IBUNa and the other active treatments versus placebo (P<0.001). IBUNa had a significantly earlier TMPR versus placebo, pooled IBUAdv/IBUMot, and IBUMot (P<0.001 for all), and a marginally faster TMPR (P=0.075) versus IBUAdv. Results for secondary endpoints were similar. Adverse events were comparable across treatment groups, with gastrointestinal disorders being most frequently reported. Most adverse events were mild or moderate.

Discussion: This novel formulation of IBUNa provided superior overall pain relief compared with placebo and more rapid onset of analgesic effect compared with standard IBU tablets. Rapid pain relief is important in the treatment of acute pain, including dental pain, and this IBUNa formulation represents a new treatment option for rapid pain relief.
