Question: what is the best drug for psoriatic arthritis?
Answer: Disease-modifying antirheumatic drugs (DMARDs). These drugs can slow the progression of psoriatic arthritis and save the joints and other tissues from permanent damage. Common DMARDs include methotrexate (Trexall, Otrexup, others), leflunomide (Arava) and sulfasalazine (Azulfidine).
