Psoriatic Arthritis Treatment – Immunobiologics
This article provides an important overview of the mechanisms and objectives in using immunobiologics to control psoriatic arthritis.
Psoriatic Arthritis – Other Medical Treatments
This article discusses other treatments for psoriatic arthritis that are often used in complement to other treatment modalities like methotrexate. Surgery, physiotherapy, gold, and anti-malarial treatments are all discussed.
TNF-a Inhibitors in Dermatology
To date, the US FDA has approved three tumor necrosis factor (TNF)-a inhibitors for use in dermatology. The distinct and targeted mechanism of action of the TNF inhibitors allows dermatologists to customize therapy to match the individual needs and characteristics of patients who are candidates for systemic therapy.
Topical Antipsoriatic Treatments in 2007
Advancements in topical antipsoriatic therapies have provided safer and more effective treatment options, especially when used in combination. Consequently, much research is underway to investigate novel treatment combinations for psoriasis in the hope that it will provide further enhancements in efficacy.
Etanercept, a TNF Antagonist for Treatment of Psoriatic Arthritis and Psoriasis
Etanercept (Enbrel®, Amgen and Wyeth), a tumor necrosis factor (TNF) antagonist, was approved in January 2002, for the treatment of psoriatic arthritis (PsA). Etanercept was evaluated for the treatment of PsA and psoriasis in a preliminary study of 60 patients and in a confirmatory phase III study of 205 patients.
With growing public reluctance to use systemic medications we can expect topical treatments for psoriasis and other skin conditions to become increasingly important in the future. These drugs are useful not only to control this disease, but also to limit the irritation caused by medications such as tazarotene and anthralin.
