This paper presents the result from a randomised, double-blind study in adults with sore throat due to upper respiratory tract infection who took flurbiprofen (n = 249) or placebo spray (n = 256). Pain relief was assessed using the Sore Throat Relief Rating Scale.
In this study, flurbiprofen spray provided significantly greater relief versus placebo from 20 min to 6 h (p < 0.0001; maximum difference: 75 min). Sore throat severity was reduced ≥-2.2 on the Sore Throat Scale from 75 min to 6 h, indicating meaningful relief. Significantly more patients taking flurbiprofen spray reported ≥30 min of ‘at least moderate’ relief versus placebo over 6 h (p < 0.0001). Most adverse events were mild.
