| Description | Tumor necrosis factor (TNF-alpha) binding antibody (chimeric IgG1). It is composed of human constant and murine variable regions. Infliximab is produced by a recombinant cell line cultured by continuous perfusion. |
| Indication/Disease | To manage the signs and symptoms, as well as to induce and maintain clinical remission in adults with moderate to severe active Crohn's disease or ulcerative colitis. Also used to manage signs and symptoms of rheumatoid arthritis (in conjunction with methotrexate), ankylosing spondylitis, psoriatic arthritis, and juvenile arthritis. |
| Pharmacodynamics | Infliximab is a chimeric human-murine anti-human tumor necrosis factor (TNF) monoclonal antibody. It binds to tumor necrosis factor alpha (TNFa) and inhibits binding of TNFa with its receptors. This reduces production of pro-inflammatory cytokines such as interleukins (IL) 1 and 6. This also limits leukocyte migration and expression of adhesion molecules by endothelial cells and leukocytes. Infliximab also limits the activation of neutrophil and eosinophil functional activity, reduces production of tissue degrading enzymes produced by synoviocytes and/or chondrocytes. Infliximab decreases synovitis and joint erosions in collagen-induced arthritis and allows eroded joints to heal. |
| Mechanism of Action | Infliximab neutralizes the biological activity of TNFa by binding with high affinity to the soluble and transmembrane forms of TNFa and inhibits binding of TNFa with its receptors. Infliximab does not neutralize TNFb (lymphotoxin a), a related cytokine that utilizes the same receptors as TNFa. Neutralization of the biological activity of TNFa leads to an overall reduction in inflammation. |
| Toxicity | NA |

| Brand Name | Inflectra |

| Brand Description | Pfizer Europe Ma Eeig |
| Prescribed For | Crohn's Disease |
| Chemical Name | NA |
| Formulation | Following reconstitution with 10 mL of Sterile Water for Injection, USP, the resulting pH is approximately 7.2. Each single-use vial contains 100 mg infliximab-dyyb, 500 mg sucrose, 0.5 mg polysorbate 80, 2.2 mg sodium dihydrogen phosphate monohydrate, and 6.1 mg di-Sodium hydrogen phosphate dihydrate. No preservatives are present. |
| Physical Appearance | sterile, white, lyophilized powder |
| Route of Administration | intravenous Injection |
| Recommended Dosage | The recommended dose of INFLECTRA is 5 mg/kg given as an intravenous induction regimen at 0, 2 and 6 weeks followed by a maintenance regimen of 5 mg/kg every 8 weeks thereafter for the treatment of adults with moderately to severely active Crohn's disease or fistulizing Crohn's disease. For adult patients who respond and then lose their response, consideration may be given to treatment with 10 mg/kg. Patients who do not respond by Week 14 are unlikely to respond with continued dosing and consideration should be given to discontinue INFLECTRA in these patients. |
| Contraindication | INFLECTRA at doses >5 mg/kg should not be administered to patients with moderate to severe heart failure. In a randomized study evaluating infliximab in patients with moderate to severe heart failure (New York Heart Association [NYHA] Functional Class III/IV), infliximab treatment at 10 mg/kg was associated with an increased incidence of death and hospitalization due to worsening heart failure. INFLECTRA should not be readministered to patients who have experienced a severe hypersensitivity reaction to infliximab products. Additionally, INFLECTRA should not be administered to patients with known hypersensitivity to inactive components of the product or to any murine proteins. |
| Side Effects | upper respiratory infections sinus infections runny or stuffy nose sore throat cough bronchitis infusion-related reactions headache abdominal pain nausea diarrhea indigestion rash itching fatigue pain fever oral thrush joint pain urinary tract infection, and high blood pressure (hypertension) |
