A randomized double-blind multicentre phase III trial was conducted to compare the tolerability and efficacy of nimesulide  and diclofenac in patients having acute shoulder pain. A meta-analysis of nimesulide clinical trials comparing nimesulide and diclofenac was also carried out.

Key take away

In patients with acute shoulder pain, nimesulide has a favourable benefit-risk ratio (reduced gastrointestinal adverse events). Nimesulide displayed superior efficacy and equal safety compared to placebo. Compared to other NSAIDS, nimesulide was found to be at least as efficacious but superior in terms of safety and tolerance. 

Background

A randomized double-blind multicentre phase III trial was conducted to compare the tolerability and efficacy of nimesulide  and diclofenac in patients having acute shoulder pain. A meta-analysis of nimesulide clinical trials comparing nimesulide and diclofenac was also carried out. 

Method

The study recruited 122 adult patients suffering from acute shoulder pain. The patients were randomly allocated to either nimesulide group (100 mg twice daily, n=62) or diclofenac (75 mg twice daily, n=60) group. Participants were followed for two weeks. At the end of the study, a global judgement of tolerability was given by patients and investigators. The benefit-risk ratio was estimated from the global judgements of tolerability and efficacy.

Result

At the end of the study, nimesulide displayed at least comparable efficacy to diclofenac. A greater number of patients dropped out in the diclofenac cohort (due to the occurrence of adverse events) compared to the nimesulide cohort (two early recovery, one adverse event, one lack of effect). The global tolerability was judged by the investigators and the patients to be good/very good in patients receiving nimesulide compared to patients receiving diclofenac, as shown in the below table:


The meta-analysis illustrated that compared to placebo, nimesulide given for two weeks is highly efficacious in managing osteoarthritis, and is at least similar to other non-steroidal anti-inflammatory drugs (NSAIDs). 

Conclusion

In all the individual studies, the benefit-risk ratio for nimesulide was found to be better since 100 mg nimesulide twice daily demonstrated equal safety and tolerability in comparison with placebo, specifically the gastrointestinal adverse events.
