Randomized Controlled TrialAnalgesic Efficacy of a New Immediate-Release/Extended-Release Formulation of Ibuprofen: Results From Single- and Multiple-Dose Postsurgical Dental Pain Studies.
Analgesic effects of ibuprofen immediate-release/extended-release (IR/ER) 600-mg tablets were evaluated in 2 randomized, double-blind, placebo-controlled dental pain studies. Patients 16-40 years old with moderate-severe pain following third-molar extraction received single-dose ibuprofen 600 mg IR/ER (formulation A or B), naproxen sodium 220 mg, or placebo (2:2:2:1; study 1) or 4 doses of ibuprofen 600 mg IR/ER (formulation A) or placebo (1:1; study 2). ⋯ Gastrointestinal adverse events predominated with placebo both after study medication administration and after rescue medication use, if applicable. Ibuprofen 600 mg IR/ER provided safe and effective analgesia after single and multiple doses.
