Analgesic onset and efficacy of a fast-acting formulation of acetaminophen in a postoperative dental impaction pain model.
Summary
To evaluate analgesic onset, efficacy, and safety of 1000 mg acetaminophen administered as two Test Acetaminophen 500 mg tablets (Test ACM) compared with 1000 mg acetaminophen administered as two commercial acetaminophen 500 mg caplets (ACM) and 400 mg ibuprofen administered as two commercial ibuprofen 200 mg liquid-filled capsules (IBU) in the dental pain model following third-molar extractions.
