Tofacitinib is an oral inhibitor of janus kinases, which is approved for the treatment of rheumatoid arthritis, psoriatic arthritis, and ulcerative colitis in adults; its efficacy in the treatment of psoriasis has also been demonstrated in clinical studies. A 10 mg daily dose has been observed to achieve a PASI75 response in 40-64% of the patients with moderate to severe psoriasis at week 12 or 16.
