A Study to Compare Meloxicam IM Once Daily Versus Meloxicam Orally Once Daily in Patients With Rheumatoid Arthritis

A Randomized, Open-labelled Study to Compare the Efficacy and Safety of Meloxicam 15 mg IM Ampoules Once Daily and Meloxicam 15 mg Tablets Administered Orally Once Daily Over a Period of 7 Days in Patients With RA.

The objective of this trial was to assess the efficacy and safety of 15 mg meloxicam i.m. once daily compared with 15 mg meloxicam tablets once daily p.o. in patients with Rheumatoid arthritis over a time period of 7 days.

This was a randomized (1:1), open-label, multi-center, active-control, parallel-group study to compare the efficacy of 15 mg meloxicam i.m. once daily compared with 15 mg meloxicam tablets once daily p.o. in patients with rheumatoid arthritis over a time period of 7 days.

Patients eligible for the trial who met all inclusion and exclusion criteria and who gave their informed consent were randomized to one of two treatment groups (i.e. meloxicam ampoule or meloxicam tablet).

The study period totaled 8-14 days included screening, randomisation, study drug administration, and 7-day follow-up. The relevant assessment were performed on the day of randomisation and 7-day follow up.

Inclusion Criteria:

• Any other rheumatological or non-rheumatological disease that could interfere with the evaluation of efficacy and safety
• Serum creatinine 125 % of the upper limit of normal range ; aspartate amino-transferase (AST/SGOT) and/or alaline amino-transferase (ALT/SGPT) 200 % of the upper limit of normal range
• Platelet count < 100,000/mm3 ; leucocytes count < 3,000/mm3
