Diflunisal in the management of sprains.

A double-blind randomized trial was carried out in 31 patients suffering from acute, minor ligamentous injuries to compare the efficacy of diflunisal in the relief of pain with that of oxyphenbutazone. Patients received either 500 mg diflunisal twice daily or 200 mg oxyphenbutazone 3-times daily for 3 days. The results of subjective assessments showed tha by Day 3 spontaneous pain had either completely resolved or markedly improved in all patients, and that diflunisal was significantly better than oxyphenbutazone on Days 1 and 3 in relieving pain on movement of the joint.
