Evaluation of oxycodone and acetaminophen in treatment of postoperative dental pain.
Although both acetaminophen and oxycodone are commonly used analgesics, they were not available as a combination until recently. Since oxycodone is not available as a single entity, there is no archival or even anectodal information on the efficacy and safety of this combination. The purpose of this study was to evaluate the relative efficacy of various doses of the combination that could be used in dental situations. The single-dose efficacy and safety of acetaminophen 500 mg., oxycodone 5 mg., acetaminophen 500 mg. + oxycodone 5 mg., acetaminophen 1,000 mg. + oxycodone 5 mg., acetaminophen 1,000 mg. + oxycodone 10 mg., and placebo were compared in outpatients who experienced moderate to severe pain after surgical removal of inpacted third molars. Analgesic data were analyzed by analysis of variance and Duncan's multiple range test. All active treatments were superior to placebo, with the high-ratio combination being the most efficacious. This treatment also had the highest incidence of limiting side effects. A positive dose-effect relationship was evident for both acetaminophen 500 mg. and 1,000 mg. and for oxycodone 5 mg. and 10 mg.
