What is Apremilast?
Apremilast is approved for the treatment of adult patients who are suitable for phototherapy or systemic therapy and have active psoriatic arthritis or moderate to severe plaque psoriasis.
Indications of apremilast?
Apremilast was authorized by the FDA for the treatment of plaque psoriasis in the following indications:
- Individuals with a history of hepatitis B or C, demyelinating illness, malignancy, chronic infection (e.g. HIV), or congestive heart failure.
- Patients who have been on systemic corticosteroid medication for an extended period of time.
Apremilast mechanism of action
Although the exact mechanism of action of this medicine is unknown, it is known that apremilast is a phosphodiesterase 4 (PDE4) inhibitor, which is involved in the activity of cyclic adenosine monophosphate (cAMP), a second messenger. Apremilast’s suppression of PDE4 results in a rise in intracellular cAMP levels. By lowering the expression of TNF-, IL-17, IL-23, and other inflammatory mediators, an increase in cAMP suppresses inflammation.
The inflammatory mediators listed above have been implicated in a variety of psoriatic disorders, as well as Behcet’s illness, where they contribute to the development of unpleasant inflammatory symptoms such as mouth ulcers, skin lesions, and arthritis. Apremilast therapy initiates a cascade that finally results in a decrease in the levels of the aforementioned mediators, alleviating inflammatory symptoms.
