Does a new formulation hurt less? study tests injection pain for common arthritis and gut disease drug

This study looked at whether switching patients to a higher concentration version of the drug adalimumab (brand name SIMLANDI™) causes less injection site pain than the standard version. It involved 324 adults in Canada who were already using adalimumab for conditions like Crohn's disease, ulcerative colitis, or various forms of arthritis. Researchers tracked pain levels, how often patients missed doses, and their overall satisfaction over six months after switching medications.
