Ala-Gln-supplemented PN was clinically safe, had better nitrogen balance, and maintained intestinal permeability in postoperative patients. The clinical outcome of the patients in study group was better; it was significantly different from the control group.

The primary objective of the study was met, demonstrating that etoricoxib 120 mg qd was non-inferior to ibuprofen 600 mg qid; further, etoricoxib was statistically superior to ibuprofen 600 mg qid according to the primary endpoint (TOPAR6) and patient global assessments of study medication. Etoricoxib and ibuprofen were generally well tolerated.
