Abstract
Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by inflammation of the synovial membranes and progressive joint destruction. Increased understanding of the immunopathology of RA has resulted in the development of new therapies to manage the disease, including several infusion-based therapies. Abatacept, a selective costimulation modulator, has been shown to be effective in clinical trials. Abatacept has a mechanism of action that is different from any other biologic RA therapy, and it provides a valuable alternative for RA patients. This article provides practical guidance for nurses to ensure safe administration and to maximize patient outcomes with abatacept.
