Objective To investigate whether methotrexate ( MTX ) administered orally to rheumatoid arthritis ( RA ) patients in split doses at 2–3 days’ interval, would result in equal or better efficacy, tolerability and compliance, without increasing toxicity compared to single weekly dose given orally or parenterally. Materials and methods One hundred and thirty‐five patients fulfilling the American College of Rheumatology ( ACR ) 2010 criteria for RA , on 7.5 mg of MTX weekly orally, with the Simplified Disease Activity Index ( SDAI ) > 11 were enrolled for a 24‐week period. Patients were randomly divided into three groups and were given MTX : Group 1 7.5 mg twice or thrice weekly orally, Group 2 15 mg or 22.5 mg in a single dose weekly orally and Group 3 15 mg or 22.5 mg in a single dose weekly as an intramuscular injection. The primary outcomes were low disease activity ( LDA ) and mean change in SDAI at week 24, whereas secondary outcomes included remission, adverse events and compliance. Results At week 24, adherence to treatment was maximum in Group 1, 69% ( P = 0.09). In intention‐to‐treat analysis at 24 weeks, Group 1, 49%, Group 2, 36% and Group 3, 47% achieved LDA ( P = 0.4). There was significant difference in mean change in SDAI at week 24 from baseline ( P = 0.008) among the groups. Group 3 patients were more uncomfortable with the mode of administration of MTX ( P = 0.003). There was no significant difference in adverse events. Conclusion Oral split doses of MTX are better than an oral single dose and similar to parenteral MTX in terms of efficacy.
