Ustekinumab(CAS: 815610-63-0)

Ustekinumab is a humanized monoclonal antibody that targets interleukin-12 (IL-12) and interleukin-23 (IL-23), which are pro-inflammatory cytokines involved in the pathogenesis of several immune-mediated diseases. It is used to treat conditions such as psoriasis and Crohn's disease.

Ustekinumab is primarily used for the treatment of moderate to severe plaque psoriasis and Crohn's disease. It is also indicated for the treatment of ulcerative colitis and atopic dermatitis in some regions.

Ustekinumab is generally considered safe, but like any medication, it carries potential risks. Side effects may include injection site reactions, infections, and allergic reactions. Patients should be monitored for signs of adverse effects and follow healthcare provider recommendations to minimize risks.

Ustekinumab should be stored at 2-8°C (36-46°F) in a refrigerator. It should not be frozen. The product should be protected from light and stored in the original vial. Do not shake the vial and use a sterile needle and syringe for administration to avoid contamination.
