Question 1

What is Infliximab?

Accepted Answer

Infliximab is a type of medication known as a monoclonal antibody that targets the immune system. It works by binding to and neutralizing tumor necrosis factor-alpha (TNF-alpha), a protein produced by the body that plays a key role in the inflammatory process.

By blocking this protein, the medication helps to decrease inflammation throughout the body. This action helps to manage the underlying biological processes that lead to persistent inflammatory responses.

Question 2

What is Infliximab used for?

Accepted Answer

Infliximab is used to treat:

Rheumatoid arthritis

Crohn's disease

Ulcerative colitis

Others

Question 3

How does Infliximab work?

Accepted Answer

Mechanism of Action

Infliximab belongs to a class of medications known as tumor necrosis factor (TNF) blockers. It is a monoclonal antibody, which is a type of protein designed to recognize and bind to a specific target in the body.

The primary target of infliximab is a substance called tumor necrosis factor-alpha (TNF-alpha). In a healthy body, TNF-alpha helps the immune system fight infections. However, in people with certain autoimmune diseases, the body produces too much of this protein. Excessive TNF-alpha leads to chronic inflammation, which can damage healthy tissues and cause symptoms like pain, swelling, and redness.

When infliximab is administered, it attaches itself to TNF-alpha molecules. This action prevents the protein from binding to its receptors on cells, effectively neutralizing its ability to trigger inflammation. By lowering the activity of TNF-alpha, infliximab helps to:

Reduce inflammation in the joints, skin, and digestive tract.

Decrease the physical symptoms associated with autoimmune disorders.

Prevent further damage to tissues and organs.

Always consult with a healthcare professional about potential side effects.

Question 7

What drug class is Infliximab?

Accepted Answer

Infliximab belongs to the TNF inhibitor drug class.

Question 8

What is the dosage of Infliximab and how do I take it?

Accepted Answer

Administration

Infliximab is given as an injection into a vein (intravenous infusion) by a healthcare provider in a medical setting, such as a doctor's office or infusion center. The infusion process usually takes at least two hours to complete.

Dosing Schedule

The treatment is generally started with several initial doses given over a few weeks. After this starting period, the medication is typically administered at regular intervals for maintenance therapy. Your healthcare provider will determine the specific schedule based on the condition being treated.

Preparation

Before receiving the infusion, your doctor may prescribe other medications, such as an antihistamine, a fever reducer, or a steroid, to help prevent or reduce the risk of an infusion reaction. You will be monitored closely by medical staff during and for a period after the infusion for any signs of a reaction.

Missed Doses

If you miss an appointment for your infusion, contact your healthcare provider as soon as possible to reschedule. It is important to receive your treatments on the schedule prescribed by your doctor to maintain the effectiveness of the medication.

Question 9

Is Infliximab safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

Research on the use of infliximab during pregnancy is limited. While studies have not consistently shown an increased risk of birth defects, the medication is known to cross the placenta, particularly during the third trimester. This exposure may affect the immune system of the newborn.

If you are pregnant or planning to become pregnant, consider the following points for discussion with a clinician:

Immune System Effects: Infants exposed to infliximab in the womb may have a higher risk of infection after birth.

Vaccination Schedule: Healthcare providers may recommend delaying live vaccines for infants who were exposed to this medication before birth. This delay often lasts for at least six months after the parent's last dose during pregnancy.

Clinical Necessity: The medication is typically used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Breastfeeding

Infliximab has been detected in human breast milk in very low levels. It is currently unknown if these small amounts cause harm to a nursing infant. Because the long-term effects are not fully established, it is important to consult with a healthcare professional to weigh the benefits of breastfeeding against the potential risks to the infant while receiving treatment.

Question 10

What forms and strengths does Infliximab come in?

Accepted Answer

Infliximab is supplied in two primary formats for administration:

Powder for Reconstitution: This is a lyophilized powder provided in vials. It must be mixed with a sterile liquid and further diluted by a healthcare professional before it is administered as an intravenous infusion.

Solution for Injection: Some versions of this medication are available as a pre-mixed liquid solution. This form is intended for subcutaneous injection, which is delivered into the fatty tissue just under the skin.

The intravenous form is typically administered by a healthcare professional in a clinical setting, while the subcutaneous form may be available in prefilled syringes or autoinjector pens for use after proper training.

Question 11

What is the FDA approval status of Infliximab?

Accepted Answer

FDA Approval and Indications

Infliximab is approved by the U.S. Food and Drug Administration (FDA) for the treatment of several chronic conditions in adults and, in some cases, children. These include:

Crohn's disease and ulcerative colitis

Rheumatoid arthritis (used in combination with methotrexate)

Ankylosing spondylitis

Psoriatic arthritis

Chronic severe plaque psoriasis

The FDA has also approved several biosimilar versions of infliximab, which are highly similar to the original reference product.

Boxed Warnings

The FDA requires a boxed warning for infliximab due to the risk of serious side effects:

Serious Infections: Patients taking infliximab are at increased risk for developing serious infections that may lead to hospitalization or death. These include tuberculosis (TB), bacterial sepsis, and invasive fungal infections.

Malignancy: Lymphoma and other cancers, some fatal, have been reported in children and adolescent patients treated with TNF blockers like infliximab. A specific type of rare cancer called hepatosplenic T-cell lymphoma has occurred primarily in adolescent and young adult males with inflammatory bowel disease.

Regulatory Requirements

Before starting treatment, the FDA recommends that patients be tested for latent tuberculosis. Healthcare providers must also monitor patients for signs of infection and certain types of skin cancer during treatment.

Question 12

What should I know about Infliximab and infusion?

Accepted Answer

How the Infusion is Given

Infliximab is delivered slowly through a needle or catheter placed into a vein, a process known as an intravenous (IV) infusion. This procedure must be performed by a healthcare professional who can monitor your response to the medication in a clinical environment.

Duration and Schedule

The infusion typically takes at least two hours to complete. The treatment schedule usually begins with three initial doses given over a six-week period (at weeks 0, 2, and 6). After these starting doses, maintenance infusions are generally administered every six to eight weeks, depending on the specific condition being treated and the patient's response.

Monitoring for Reactions

Because some patients may experience an infusion reaction, healthcare providers will watch you closely during the procedure and for a period of time afterward. Symptoms of a reaction can include:

Fever or chills

Chest pain

Shortness of breath

High or low blood pressure

Itching or rash

In some cases, delayed reactions can occur several days after the infusion. It is important to notify your doctor if you experience muscle or joint pain, fever, or swelling of the face and hands within 12 days of receiving a dose.
