A double-blind single dose trial was made of floctafenine 200 mg versus dihydrocodeine 30 mg in 100 patients complaining of jaw pain following oral surgery under general anaesthesia. There was no statistical difference between the two analgesics for the whole group, but dihydrocodeine was better for the relief of more severe pain.
