[Drug therapy of rheumatoid arthritis: where do biologics and novel synthetic disease-modifying antirheumatic drugs stand today?].

Biologics and Janus kinase (JAK) inhibitors play an important role in the treatment of rheumatoid arthritis. As new therapeutic developments have emerged in recent decades, the morbidity and mortality of rheumatoid arthritis have been significantly reduced. The characterization of the structure and function of immune cell receptors has led to the development of biologics that specifically inhibit cytokines and immune cell receptors. An important therapeutic addition was the approval of JAK inhibitors, which act directly on intracellular signaling by tyrosine kinases. This article provides an overview of the current therapeutic options for rheumatoid arthritis with a special focus on indication, mechanism of action and the place in the treatment algorithm of biologics and JAK inhibitors.
