Outcome Measures
Primary Outcome Measures
- To assess whether the efficacy of glucosamine + meloxicam sulfate treatment is superior to the efficacy of treatment with glucosamine sulfate + chondroitin sulfate in improving pain in subjects with symptomatic primary knee OA treated for 4 weeks. [4 weeks]
Absolute variation of the "pain" subscale score of the WOMAC questionnaire (0 to 100mm) 4 weeks (V2) after starting treatment in relation to the basal score (VR);

-
Presence of painful symptoms in the target knee in the last 3 months due to osteoarthritis.
-
Visual analogue scale for evaluation of knee osteoarthritis pain by the research participant ≥ 40 mm at the screening visit.
-
Mean score ≥ 40mm on the "pain" subscale (0 to 100mm) on the target knee of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaire at the randomization visit.
-
ACR functional class from I to III.
-
