Indomethacin or sulindac at night in rheumatoid arthritis.

The effects of indomethacin and sulindac in relieving troublesome morning stiffness and nighttime pain were tested in a double-blind cross-over trial. Thirteen of the 17 patients who completed the trial preferred indomethacin which was found to be superior to sulindac in all the parameters tested. Sulindac did, however, have some beneficial effect and can be used as an alternative to indomethacin when this drug cannot be used as the agent of first choice.
