Adverse events, particularly gastrointestinal, partially offset the
therapeutic value of NSAIDs. The abilities of nimesulide to inhibit COX- 2
preferentially and to exert other novel anti-inflammatory actions are
consistent with good efficacy and safety. This is borne out by a double-
blind multicentre comparison of nimesulide and diclofenac in 122 patients
with acute shoulder, and by a meta-analysis of various nimesulide trials.
At the end of the 14 day double-blind study, nimesulide was at least as
effective as diclofenac (investigator ratings: good/very good in 79.0% of
patients given nimesulide, and 78.0% with diclofenac; patient ratings:
good/very good in 82.3 and 78.0% respectively). Four patients (6.5%)
dropped out in the nimesulide group (two early recovery, one lack of
effect, one adverse event), compared with 13 (21.7%) in the diclofenac
group, due mainly to adverse events (P=0.003). Global tolerability was
judged by the investigators to be good/very good in 96.8% of the nimesulide
group compared with 72.9% of those given diclofenac. Judgements by the
patients were 96.8 and 78.0% respectively. Both differences are highly
significant statistically. The meta-analysis demonstrates that nimesulide
given for 2 weeks is far more efficacious than placebo in treating
osteoarthritis, and is at least comparable to other NSAIDs The benefit-
risk ratio for nimesulide was better in all individual studies since 100 mg
nimesulide twice daily was about equal to placebo in safety and
tolerability, especially regarding gastrointestinal adverse events.
