Otezla (apremilast) is an innovative medication that has made significant advances in the treatment of certain inflammatory conditions. Specifically, it is used to manage symptoms of psoriatic arthritis, moderate to severe plaque psoriasis, and oral ulcers associated with Behçet’s Disease. As a small molecule inhibitor, Otezla offers a distinct mechanism of action compared to biologic drugs, which often require injection or infusion. Here's a closer look at Otezla, how it works, and its clinical applications.
Understanding Otezla and Its Mechanism of Action
Otezla is classified as a phosphodiesterase 4 (PDE4) inhibitor. This class of drugs works by inhibiting an enzyme called phosphodiesterase 4, which is involved in the process of inflammation. By inhibiting PDE4, Otezla helps to reduce the production of various inflammatory substances in the body. This reduction in inflammation is particularly beneficial in conditions like psoriatic arthritis and plaque psoriasis, where overactive inflammation plays a central role.
Conditions Treated by Otezla
1. Psoriatic Arthritis:
- For patients with psoriatic arthritis, Otezla can reduce joint pain and swelling, improve physical function, and slow the progression of joint damage. It is suitable for patients who have had an inadequate response to or cannot tolerate other systemic therapies.
2. Plaque Psoriasis:
- Otezla is approved for the treatment of patients with moderate to severe plaque psoriasis who are candidates for phototherapy or systemic therapy. It helps to reduce the plaque thickness, scaling, and redness.
3. Behçet’s Disease:
- Otezla has been shown to significantly reduce the number of oral ulcers and pain in patients with Behçet’s Disease, a rare inflammatory disorder.
Administration and Dosage
Otezla is administered orally in tablet form, which is a significant advantage for patients who prefer not to use injectable medications. The typical dosing regimen begins with a titration period to minimize gastrointestinal side effects associated with initial therapy. Starting at a lower dose, the dosage is gradually increased over the first five days until the recommended maintenance dose is reached. The usual maintenance dose is 30 mg taken twice daily.
Benefits of Otezla
- Oral Administration: As a pill, Otezla is easy to take and does not require the more invasive administration associated with many biologic treatments.
- Targeted Action: By specifically targeting PDE4, Otezla effectively reduces inflammation related to psoriatic disease and Behçet’s Disease without the broad immune suppression seen with some other therapies.
- Improvement in Symptoms: Clinical trials have shown that Otezla effectively reduces symptoms, improves physical function, and enhances quality of life for individuals with psoriatic arthritis, plaque psoriasis, and oral ulcers associated with Behçet’s Disease.
Side Effects and Considerations
While Otezla is generally well-tolerated, it can cause side effects such as diarrhea, nausea, and headache, particularly when the treatment is initiated. Some patients may experience weight loss or depression, and it is important to monitor these symptoms and discuss them with a healthcare provider.
FAQs

Conclusion
Otezla represents a significant advancement in the treatment of inflammatory conditions related to psoriasis and Behçet’s Disease. Its mechanism as a PDE4 inhibitor offers a valuable alternative to those who may not be suitable for or wish to avoid biologic therapies. By understanding how Otezla works and the benefits it provides, patients and healthcare providers can make informed decisions about incorporating this medication into treatment plans.
