Multidose flurbiprofen 8.75 mg lozenges in the treatment of sore throat: a randomised, double-blind, placebo-controlled study in UK general practice centres

Abstract

The flurbiprofen 8.75 mg lozenge is a novel formulation that combines a demulcent effect with the analgesic activity of a non-steroidal anti-inflammatory drug. Previous controlled clinical studies have demonstrated the single- and multi-dose efficacy of these lozenges over placebo. The current study reflected the treatment of sore throat in general practice, investigating multiple dose efficacy where patients also had access to concomitant antibiotics and rescue medication. The efficacy of flurbiprofen 8.75 mg lozenge over placebo was confirmed: there was a significant difference in pain relief obtained from flurbiprofen 8.75 mg versus placebo, along with a significant reduction of difficulty in swallowing from the time of first assessment and significantly greater reductions in throat soreness and difficulty in swallowing throughout the study period. Additionally, significant benefit over placebo was demonstrated where concomitant antibiotic use was introduced, indicating that flurbiprofen 8.75 mg lozenges can be co-administered when antibiotic therapy is appropriate. No significant safety issues were identified.
