Psoriatic arthritis (PsA) is a disease with heterogeneous manifestations in patients who have manifest or latent psoriasis. It comprises both musculoskeletal and non-musculoskeletal manifestations. Active chronic PsA is often accompanied by cardiovascular, psychological and metabolic complications. Although the quantity of disease-modifying antirheumatic drugs (DMARDs) indicated for PsA has increased, clinicians still require some guidance in decision-making. Based on the latest evidence-based research results, the European League Against Rheumatism (EULAR) in 2019 developed the recommendations for the pharmacological management of PsA updated in 2015 with new recommendations. This paper interprets the update contents of the guideline to provide references for the clinical treatment of PsA.
