Correspondence analysis and the Pearson Chisquare test have been used to assess tolerability, compliance, and presence of adverse events.ResultsPatient compliance with and tolerability on the treatments have been analyzed utilizing a detailed questionnaire. Compliance with treatment was really great for nimesulide and acetaminophen, very good for Meriva 1.5 g (corresponding to 300 mg of curcumin) and fair to fantastic for Meriva 2 g (corresponding to 400 mg of curcumin, Table 2). The latter observation may be explained by the truth that intake of four pills was uncomfortable for some subjects. Generally, all treatment options had been nicely tolerated (Table 3), with tolerability getting outstanding for acetaminophen and Meriva 1.five g, poor to fair for nimesulide, and fair to good for Meriva 2 g. No unwanted effects were noticed for acetaminophen and Meriva 1.5 g, but a few subjects reported gastrointestinal discomfort (robust heartburn and gastroesophageal reflux, requiring antacid therapy) with nimesulide. Meriva 2 g also induced stomach heaviness, nausea, and heartburn in some participants, mostly those that had previously reported these negative effects with nimesulide (Table four). Having said that, in contrast to the gastric discomfort linked with nimesulide, that induced by Meriva had an early onset, so was possibly nonspecific, getting connected, apart from an increased sensitivity to gastric injury, towards the sheer challenge of ingestion of 4 tablets.
