Ustekinumab
/api/v1/drug/ustekinumabMechanism of action
Sourced from openFDAUstekinumab products are human IgG1қ monoclonal antibodies that binds with specificity to the p40 protein subunit used by both the IL-12 and IL-23 cytokines. IL-12 and IL-23 are naturally occurring cytokines that are involved in inflammatory and immune responses, such as natural killer cell activation and CD4+ T-cell differentiation and activation.

Warnings & precautions
Sourced from openFDAInfections: Serious infections have occurred. Avoid starting YESINTEK during any clinically important active infection. If a serious infection or clinically significant infection develops, discontinue YESINTEK until the infection resolves. ( 5.1 ) Theoretical Risk for Particular Infections: Serious infections from mycobacteria, salmonella, and Bacillus Calmette-Guerin (BCG) vaccinations have been reported in patients genetically deficient in IL-12/IL-23. Consider diagnostic tests for these infections as dictated by clinical circumstances. ( 5.2 ) Tuberculosis (TB) : Evaluate patients for TB prior to initiating treatment with YESINTEK. Initiate treatment of latent TB before administering YESINTEK. (5.3) Malignancies: Ustekinumab products may increase risk of malignancy. The safety of ustekinumab products in patients with a history of or a known malignancy has not been evaluated. (5.4) Serious Hypersensitivity Reactions: If a severe or other clinically significant hypersensitivity reaction occurs, discontinue YESINTEK immediately and initiate appropriate medical treatment. (5.5) Posterior Reversible Encephalopathy Syndrome (PRES): If PRES is suspected, treat promptly, and discontinue YESINTEK. (5.6) Immunizations : Avoid use of live vaccines in patients during treatment with YESINTEK. (5.7) Noninfectious Pneumonia: Cases of interstitial pneumonia, eosinophilic pneumonia, and cryptogenic organizing pneumonia have been reported during post-approval use of ustekinumab products. If diagnosis is confirmed, discontinue YESINTEK and institute appropriate treatment.

Use in specific populations
Sourced from openFDA8.1 Pregnancy Risk Summary Available data from the Organization of Teratology Information Specialists (OTIS)/MotherToBaby Pregnancy Registry, published literature and pharmacovigilance in pregnant women have not identified a ustekinumab-associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes ( see Data ). There are risks to the mother and the fetus associated with inflammatory bowel disease (IBD) in pregnancy. In animal reproductive and developmental toxicity studies, no adverse developmental effects were observed in offspring after administration of ustekinumab to pregnant monkeys at exposures greater than 100 times the maximum recommended human dose (MRHD). All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage of clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Clinical Considerations Disease-associated Maternal and Embryo/Fetal Risk Published data suggest that the risk of adverse pregnancy outcomes in women with IBD is associated with increased disease activity. Adverse pregnancy outcomes include preterm delivery (before 37 weeks of gestation), low birth weight (less than 2500 g) infants, and small for gestational age at birth.
Pharmacokinetics
Sourced from openFDA- Metabolism
- Absorption In adult subjects with plaque psoriasis, the median time to reach the maximum serum concentration (T max ) was 13.5 days and 7 days, respectively, after a single subcutaneous administration of 45 mg (N=22) and 90 mg (N=24) of ustekinumab. In healthy subjects (N=30), the median T max value (8.5 days) following a single subcutaneous administration of 90 mg of ustekinumab was comparable to that observed in subjects with plaque psoriasis.
Overdosage
Sourced from openFDASingle doses up to 6 mg/kg intravenously have been administered in clinical trials without dose-limiting toxicity. In case of overdosage, monitor the patient for any signs or symptoms of adverse reactions or effects and institute appropriate symptomatic treatment immediately. Consider contacting the Poison Help line 1-800-222-1222 or a medical toxicologist for additional overdose management recommendations.
