Important Tests and Risks

Risk of Drug Interaction

There are several medications that can interact with Otezla. It is important for patients to make sure that their doctor is aware of all medications and supplements that they are taking along with Otezla.

Science

How Otezla Works

Otezla inhibits an enzyme called phosphodiesterase-4. This enzyme breaks down a chemical messenger in the body called cyclic adenosine monophosphate.

By inhibiting phosphodiesterase-4, less cyclic adenosine monophosphate gets broken down in the body. This increases cyclic adenosine monophosphate levels, especially in inflammatory cells where phosphodiesterase-4, is the dominant enzyme responsible for breaking down cyclic adenosine monophosphate.

An increase in cyclic adenosine monophosphate levels “turns down” (or down-regulates) a number of cellular signals called cytokines that increase inflammation, including Tumor Necrosis Factor Alpha, interleukin 17, interleukin 23, and others.

The increase in cyclic adenosine monophosphate levels also “turns up” (or up-regulates) the cellular signal interleukin 10 which can reduce inflammation.

It is not understood how exactly these changes produces the specific effects seen in patients that take Otezla. However, it is understood that this medication can improve psoriasis symptoms, and can reduce the joint pain and tenderness experienced by psoriatic arthritis patients.
