Study Notes
5-Aminosalicylic Acid (5-ASA) Derivatives
- Examples: balsalazide (Colazal), mesalamine (Apriso, Asacol, Delzicol, Lialda, Pentasa), olsalazine (Dipentum), sulfasalazine (Azulfidine)
- Work by inhibiting inflammatory mediators in the intestines, such as leukotrienes and tumor necrosis factor.
- Are metabolized by bacteria in the intestines to an active form that acts locally on inflamed areas.
- Available in oral, enema, or suppository forms.
- Assess for contraindications in patients with a history of hypersensitivity to sulfonamides or salicylates, or intestinal or urinary tract obstruction.
- Monitor for possible adverse effects including headache, diarrhea, dizziness, rhinitis, sinusitis, skin rash, and pruritus.
Corticosteroids
- Examples: budesonide (Entocort, Uceris), hydrocortisone (Colocort, Cortenema), prednisone (Prednisone Intensol), prednisolone (Orapred, Pediapred)
- Suppress immune system activity and leukocyte migration.
- Available in oral time-release forms (dissolving in the ileum and colon) or as enemas for topical action.
- Monitor for signs of headache, acne, infections, and Cushing's disease.
Biologic Therapies: Tumor Necrosis Factor (TNF) Inhibitors
- Examples: adalimumab (Humira), certolizumab (Cimzia), golimumab (Simponi, Simponi Aria), infliximab (Inflectra, Remicade, Renflexis)
- Interrupt endogenous tumor necrosis factor alpha (TNFα) to suppress inflammation in the intestine.
- Are monoclonal antibodies.
- Administered subcutaneously, rotating injection sites.
- Monitor for signs of infection or cancer.
- Monitor for possible side effects, including headache, skin rash, positive ANA titer, and increased creatine phosphokinase.
Integrin Antagonists (Alpha-4 Integrin Inhibitors)
- Examples: natalizumab (Tysabri), vedolizumab (Entyvio)
- Bind with the adhesion molecule alpha-4 integrin to prevent leukocyte migration to the intestine.
- Are monoclonal antibody drugs.
- Administered intravenously.
- Monitor for signs of infection.
- Monitor for possible side effects of headache, nausea, fatigue, depression, and skin rash.
Interleukin-12/23 Inhibitors
- Example: ustekinumab (Stelara)
- Bind to inflammatory substances interleukin-12 and interleukin-23 to prevent activation of natural killer cells and tumor necrosis factor.
- Administered subcutaneously, rotating injection sites.
- Monitor for infections, especially TB and fungal infections.
- Monitor for headache, nausea, fatigue, depression, and skin itching.
- Educate patients about vaccines; they should not receive live vaccines while on ustekinumab, and non-live vaccines may not be effective.
Janus-Associated Kinase (JAK) Inhibitors
- Example: tofacitinib (Xeljanz)
- Inhibit intracellular JAK enzymes that stimulate immune cell activity, natural killer cells, immunoglobulins, and B cells.
- Administered orally.
- Monitor for side effects of infection.
