Abstract:
In a randomized double-blind study, 120 patients with moderate to strong pain after surgical removal of wisdom teeth were given the following in single oral doses: 100-mg enteric-coated diclofenac tablets; 1 g acetaminophen (INN, paracetamol); 1 g acetaminophen plus 60 mg codeine; 100-mg enteric-coated diclofenac tablets plus 1 g acetaminophen; or 100-mg enteric-coated diclofenac tablets plus 1 g acetaminophen plus 60 mg codeine. Patients recorded pain intensity and pain relief for 8 hours. Upside assay sensitivity was confirmed because acetaminophen plus codeine was superior to acetaminophen. Diclofenac plus acetaminophen with and without codeine had superior analgesic effect compared with diclofenac, acetaminophen, or acetaminophen plus codeine. Addition of 60 mg codeine increased the degree of side effects. These results support the clinical practice of combining diclofenac with acetaminophen for acute pain. Of clinical importance are superior and prolonged analgesia and fewer side effects after enteric-coated diclofenac tablets plus acetaminophen compared with acetaminophen plus codeine.
