apremilast (Otezla): Click for Side Effects and Dosing

What is apremilast, and how does it work (mechanism of action)?

Apremilast is an oral medication used to treat
adults with active psoriatic arthritis (a form of arthritis that affects some
people with psoriasis). It is also used to treat moderate to severe
psoriasis in patients who are candidates for phototherapy or systemic therapy. Apremilast works by reducing production of an enzyme known as phosphodiesterase
4(PDE4). This may lead to a reduction in chemicals that cause inflammation in
the body. However the exact mechanism in treating psoriatic arthritis and plaque
psoriasis is not known. In clinical studies, patients with psoriatic arthritis
had improvement in tender and swollen joints, as well as physical function.
Patients with plaque psoriasis had reductions in redness, scaliness and
thickness of the skin. The FDA approved apremilast in March 2014.
