Ilumya (tildrakizumab) is a prescription medication used to treat moderate to severe plaque psoriasis in adults who are candidates for systemic therapy or phototherapy. It is a monoclonal antibody that works by blocking the p19 subunit of interleukin-23 (IL-23), a cytokine that plays a key role in the development and progression of psoriasis.
Uses
Ilumya is used to treat moderate to severe plaque psoriasis in adults. Plaque psoriasis is a chronic autoimmune disease that causes red, scaly patches of skin to form. Ilumya can help to clear these patches and improve the appearance and comfort of the skin.
Storage Conditions
Ilumya should be stored in the refrigerator at 36°F to 46°F (2°C to 8°C). Do not freeze. Ilumya can be kept at room temperature for up to 24 hours.
Mechanism of Action
Ilumya is a monoclonal antibody that binds to the p19 subunit of IL-23 and blocks its interaction with the IL-23 receptor. IL-23 is a cytokine that plays a key role in the development and progression of psoriasis. By blocking IL-23, Ilumya can help to reduce inflammation and improve the symptoms of psoriasis.
