Diflunisal: efficacy in postoperative pain.

Abstract

1. Seven hundred and forty patients complaining of pain after oral or orthopaedic surgery or episiotomy were studied in five single dose or short-term double-blind, controlled, randomized studies comparing efficacy and safety of diflunisal with that of acetylsalicylic acid, glafenin or placebo. 2. Diflunisal was found to be effective in relieving postoperative pain in 75-85% of patients. A twice day dosage schedule seems to be clinically adequate, 375 mg twice daily proving to be equally effective as glafenin 200 mg three times daily. No serious drug-related clinical or laboratory adverse experiences were encountered in any of the five studies.
