Biologic Drugs to Treat Rheumatoid Arthritis

Overview

Biologic drugs are a type of medicine that can help treat rheumatoid arthritis (RA). They are immune treatments that target specific parts of the immune system involved in inflammation. Biologics aim to provide relief from symptoms and prevent the immune system from attacking healthy tissues lining the joints, which is what causes pain, swelling, and deformities in RA.

The disease can have devastating, debilitating effects, including flu-like symptoms, weight loss, and overall fatigue. Traditional treatments may not always be effective for everyone with RA. When those treatments fail, biologics offer an alternative. For some, RA can lead to work disability within 23 years of onset. Biologics can make a significant difference in managing symptoms and improving quality of life for those living with the condition.

How Medication Works

Biologic drugs work by targeting specific parts of the immune system that are involved in inflammation. These drugs interrupt the signals that lead to inflammation and joint damage in rheumatoid arthritis. Here's how biologic drugs work for treating RA:

• Targeting specific proteins:
• Biologic drugs are designed to target specific proteins or cytokines involved in the inflammatory process. The first type of biologic drugs approved for treating RA were anti-TNF biologics. These drugs block the actions of tumor necrosis factor (TNF), a protein that activates specific cells in the body, leading to joint damage.
• Interrupting immune system signals:
• Biologics work by interrupting immune system signals that contribute to inflammation and joint tissue damage. They can disrupt chemical signals involved in inflammation or directly interfere with the activity of T-cells or B-cells, which play a role in the inflammatory process.
• Controlling RA inflammation:
• Biologics are more targeted than conventional disease-modifying antirheumatic drugs and can be more effective at controlling RA progression. These drugs specifically target mediators of RA inflammation, helping to reduce pain, swelling, and joint damage.
• Different delivery methods:
• Biologic treatments for RA can be administered through self-injectable pens, pre-filled syringes, or infusions. Self-injectable pens allow individuals to inject the drug into their skin using an auto-injector, while pre-filled syringes require manual injection. Infusions are delivered intravenously in a hospital or clinic setting or even at home.

Like any medication, biologic drugs can have side effects. Common side effects include injection site reactions, upper respiratory infections, and headaches. However, serious side effects are rare and should be discussed with a healthcare provider.

In summary, biologic drugs for treating rheumatoid arthritis work by targeting specific parts of the immune system involved in inflammation and interrupt signals that contribute to joint tissue damage. These medications can help control RA progression and reduce symptoms such as pain and swelling in approximately 60% of people with RA.

How to Use Medication

To use or take biologic drugs, follow these steps:

• Prepare the necessary supplies: Lay out an alcohol swab, sharps container, and cotton ball or gauze with your syringe.
• Choose an injection site: The front of the thigh or stomach is a good choice, but make sure to avoid going closer than 2 inches toward the belly button or too close to a previous injection site.
• Before starting the injection process, thoroughly wash your hands.
• Use the alcohol swab to clean the chosen injection site.
• Hold the needle in one hand and gently lift off the needle cover with the other hand. Be sure not to touch the needle itself.
• Check the medication: The medication in the syringe should be clear or yellow, indicating that it is safe to use. If it appears cloudy or has large flakes, do not use it.
• Hold the body of the syringe with your thumb and index fingers.
• Use your other hand to squeeze the injection site, creating a raised platform.
• Insert the needle at a 45-degree angle and push the plunger in until all of the medication is dispensed.
• Slowly remove the needle from the skin, keeping it at a 45-degree angle.
• After removing the needle, cover the injection site with a cotton ball or gauze.
• Place used syringes in a sharps container for proper disposal.

Now let's talk about precautions and potential side effects of biologic drugs:

• Before starting biologic drug treatment, it's important to talk to your doctor about any medical tests you may need before, during, or after treatment.
• Ask your doctor about signs and symptoms of adverse side effects that you should watch out for.
• Be sure to discuss medications, supplements, or vaccines that you should avoid while taking biologic drugs.
• Consult your doctor before getting any vaccines while on biologic drugs, as some live virus vaccines may not be recommended.

Potential side effects include:

• Fatigue
• Headache
• Pain around the injection site
• Aching muscles and joints
• Sore throat
• Allergic reactions: If you suspect an allergic reaction, contact your doctor immediately.

It's important to note that while biologic drugs are generally safe to use, they can have interactions with other medications. Make sure to inform your doctor about all over-the-counter or prescription medications, supplements, herbal medications, and vitamins you are taking before starting biologic treatment.

If you have any concerns or questions about using or taking biologic drugs, always consult with your doctor for personalized advice and guidance tailored to your specific needs.
