The purpose of the present study was to evaluate the possible therapeutic effects and the safety of Mangifera indica extract (Vimang tablets, 300 mg) combined with methotrexate (MTX) on reducing disease activity in rheumatoid arthritis (RA). Twenty patients with active RA underwent a year of treatment with MTX (12.5 mg/week) associated to non‐steroidal anti‐inflammatory drugs (NSAIDs) and/or prednisone (5–10 mg/day) were randomly allocated to the experimental group (n = 10), that received the extract supplementation (900 mg/day) or preceding usual treatment (n = 10) during 180 days. RA activity was evaluated using the tender and swollen joint counts, erythrocyte sedimentation rate, disease activity score‐28 (DAS 28), visual analogue scale (VAS) and health assessment questionnaire (HAQ). Treatment's efficacy was demonstrated with ACR criteria. Only the patients of MTX‐Vimang group revealed statistically significant improvement in DAS 28 parameters with respect baseline data but no differences were observed between groups. ACR improvements amounted 80% only in MTX‐Vimang group at the 90 days (p < 0.001). In MTX‐Vimang group, 100% of patients decreased NSAIDs administration (p < 0.01) and 70% of those eradicated gastrointestinal side effects (p < 0.01) ensuing of the preceding treatment. Other adverse effects were not reported.
