Ustekinumab: differential use in psoriasis

Chronic plaque psoriasis is a systemic disease affecting over 3% of the population, and many patients are unsatisfied with their current treatment regimen. With advances in understanding of the pathophysiology of psoriasis, new therapeutic options are being developed. The newest of these agents, ustekinumab, offers patients rapid results and the convenience of four annual subcutaneous doses, with efficacy and safety profiles comparable with those of other biologics. However, ustekinumab has been on the market in the US for less than 2 years and will require years of extensive use before the full adverse event profile is fully understood. The purpose of this paper is to summarize the treatment options currently available for psoriasis, with an emphasis on ustekinumab in order to give prescribers an overview of the available data and allow them to make educated and informed prescribing decisions.
