Arthritis Medications

Arthritis is a condition associated with swelling and inflammation of the joints, which often results in pain and restriction of movement. The most common forms of arthritis are osteoarthritis, which is a breakdown of the cartilage in the joints, and rheumatoid arthritis, which is an inflammation of the lining of the joints and possibly other body tissues. Muscular injuries can also cause pain, inflammation and swelling.

What causes Arthritis and who is at risk?

Arthritis is a result of a breakdown in cartilage.

Cartilage protects joints and enables smooth movement by absorbing shock when pressure is placed on a joint, for example when you walk. Without the usual amount of cartilage, the bones rub together and this causes pain, swelling (inflammation), and stiffness.

Joint inflammation can occur for a variety of reasons, including:

• Broken bones
• Infections (usually caused by bacteria or viruses)
• An autoimmune disease (where the body attacks itself because the immune system believes a body part is foreign)
• General "wear and tear" on joints

Often, the inflammation goes away once the injury has healed, the disease is treated, or once the infection has been cleared. However, with some injuries and diseases, the inflammation does not go away or the cartilage is destroyed and long-term pain and deformity results. When this happens, the disease is called chronic arthritis.

Osteoarthritis is the most common type of arthritis and is more likely to occur with increasing age. It can occur in any of the joints but is most common in the hips, knees or fingers. Risk factors for osteoarthritis include:

• Being overweight
• Having previously injured the affected joint
• Using the affected joint in a repetitive action that puts stress on the joint (baseball players, ballet dancers, and construction workers are all at risk)

Arthritis can occur in both men and women and in individuals of all ages. About 37 million people in America have some form of arthritis.

Types of Arthritis

 As mentioned earlier, the most common forms of arthritis are Osteoarthritis and Rheumatoid arthritis. However, there are numerous forms of arthritis, including:

• Rheumatoid arthritis (in adults)
• Juvenile rheumatoid arthritis (in children)
• Systemic lupus erythematosus (SLE)
• Gout
• Scleroderma
• Psoriatic arthritis
• Ankylosing spondylitis
• Reiter's syndrome (reactive arthritis)
• Adult Still's disease
• Viral arthritis
• Gonococcal arthritis
• Other bacterial infections ( non-gonococcal bacterial arthritis )
• Tertiary Lyme disease (the late stage)
• Tuberculous arthritis
• Fungal infections such as blastomycosis

Symptoms of Arthritis

A person suffering from arthritis may experience any of the following:

• Joint pain
• Joint swelling
• Stiffness, especially in the morning
• Warmth around a joint
• Redness of the skin around a joint
• Reduced ability to move the joint

Diagnosis

A doctor will first note your symptoms and will then look at your medical history in detail to see if arthritis or another musculoskeletal problem is the likely cause of those symptoms.

He/she will then perform a thorough physical examination to see if there is any fluid collecting around the joint (an abnormal build up of fluid around a joint is called "joint effusion.") The joint may be tender when it is gently pressed, and it may also be warm and red (especially if you have infectious arthritis or autoimmune arthritis). You may also find it painful or difficult to rotate the joints in some directions (this is known as "limited range-of-motion.")

After this initial physical examination, your doctor may then ask you to undertake a number of different tests, depending on what they suspect to be the cause of your symptoms. Often, you will need to have a blood test and joint x-rays. You may also need to have a test where joint fluid is removed from the joint with a needle; the fluid will then be examined under a microscope to check for infection and for other causes of arthritis, such as crystals, which cause gout.

If arthritis is diagnosed and treated early, you can prevent joint damage. Find out if you have a family history of arthritis and share this information with your doctor, even if you have no joint symptoms. In some autoimmune forms of arthritis, the joints may become deformed if the disease is not treated - such joint deformities are the hallmarks of severe, untreated rheumatoid arthritis. Osteoarthritis may be more likely to develop if you abuse your joints (injure them many times or over-use them when they are injured). Take care not to overwork a damaged or sore joint. Similarly, avoid excessive repetitive motions. Excess weight also increases the risk for developing osteoarthritis in the knees, and possibly in the hips and hands.

Call your doctor if:

• Your joint pain persists beyond 3 days.
• You have severe unexplained joint pain.
• The affected joint is significantly swollen.
• You have a hard time moving the joint.
• Your skin around the joint is red or hot to the touch.
• You have a fever or have lost weight unintentionally.

Treatment Options

The treatment of arthritis depends on the particular cause of the disease, on the joints that are affected, on the severity of the disorder and on the effect it has on your daily activities. Your age and occupation will also be taken into consideration when your doctor works with you to create a treatment plan.

If possible, treatment will focus on eliminating the underlying cause of the arthritis. However, sometimes the cause is NOT curable, as with osteoarthritis and rheumatoid arthritis. In this case, the aim of treatment will be to reduce pain and discomfort and prevent further disability.

Symptoms of osteoarthritis and other long-term types of arthritis can often be improved without medications. In fact, making lifestyle changes without medications is preferable for osteoarthritis and other forms of joint inflammation. If needed, medications should be used in addition to lifestyle changes.

Exercise is important for arthritis sufferers because it helps maintain healthy joints, relieve stiffness, reduce pain and fatigue, and improve muscle and bone strength. Your exercise program should be tailored to you as an individual. Work with a physical therapist to design an individualized program, which should include:

• Range of motion exercises for flexibility
• Strength training for muscle tone
• Low-impact aerobic activity (also called endurance exercise)

A physical therapist can apply heat and cold treatments as needed and fit you for splints or orthotic (straightening) devices to support and align joints. This may be necessary for rheumatoid arthritis in particular. Your physical therapist may also consider water therapy, ice massage, or transcutaneous nerve stimulation (TENS).

Rest is just as important for you as exercise. Sleeping 8 to 10 hours per night and taking naps during the day can help you recover from a flare-up more quickly and may even help prevent exacerbations. You should also:

• Avoid positions or movements that place extra stress on your affected joints.
• Avoid holding one position for too long.
• Reduce stress, which can aggravate your symptoms. Try meditation or guided imagery. And talk to your physical therapist about yoga or tai chi.
• Modify your home to make activities easier. For example, have grab bars in the shower, the tub, and near the toilet.

Other measures to try include:

• Taking glucosamine and chondroitin -- these form the building blocks of cartilage, the substance that lines joints. These supplements are available at health food stores or supermarkets. Early studies have indicated that these compounds are safe and may improve your arthritis symptoms. More research is underway.
• Eat a diet rich in vitamins and minerals, especially antioxidants like vitamin E. These are found in fruits and vegetables. Get selenium from Brewer's yeast, wheat germ, garlic, whole grains, sunflower seeds, and Brazil nuts. Get omega-3 fatty acids from cold water fish (like salmon, mackerel, and herring), flaxseed, rapeseed (canola) oil, soybeans, soybean oil, pumpkin seeds, and walnuts.
• Apply capsaicin cream (derived from hot chili peppers) to the skin over your painful joints. You may feel an improvement after applying the cream for 3-7 days.

Medications

Your doctor will select the most appropriate medication for your form of arthritis. The first drugs he/she will most likely recommend are generally available without a prescription. These include:

• Acetaminophen (Tylenol) -- recommended by the American College of Rheumatology and the American Geriatrics Society as first-line treatment for osteoarthritis. Take up to 4 grams a day (2 extra-strength Tylenol every 6 hours). This can provide significant relief of Arthritis Pain without many of the side effects of prescription drugs. DO NOT exceed the recommended DOSes of acetaminophen or take the drug in combination with large amounts of alcohol. These actions may damage your liver.
• Aspirin, ibuprofen, or naproxen -- these nonsteroidal anti-inflammatory (NSAID) drugs are often effective in combating Arthritis Pain. However, they have many potential risks, especially if used for a long time. They should not be taken in any amount without consulting your doctor. Potential side effects include heart attack, stroke, stomach ulcers, bleeding from the digestive tract, and kidney damage. In April 2005, the FDA asked drug manufacturers of NSAIDs to include a warning label on their product that alerts users of an increased risk for heart attack, stroke, and gastrointestinal bleeding. If you have kidney or liver disease, or a history of gastrointestinal bleeding, you should not take these medicines unless your doctor specifically recommends them.

Prescription medicines include:

• Cyclo-oxygenase-2 (COX-2) inhibitors -- These drugs block an inflammation-promoting enzyme called COX-2. This class of drugs was initially believed to work as well as traditional NSAIDs but with fewer stomach problems. However, numerous reports of heart attacks and stroke have prompted the FDA to re-evaluate the risks and benefits of the COX-2s. Rofecoxib (Vioxx) and valdecoxib (Bextra) have been withdrawn from the U.S. market following reports of heart attacks in patients taking the drugs. Celecoxib (Celebrex) is still available, but labeled with strong warnings and a recommendation that it be prescribed at the lowest possible DOSe for the shortest duration possible. Talk to your doctor about whether COX-2s are right for you.
• Corticosteroids ("steroids") -- these are medications that suppress the immune system and symptoms of inflammation. They are commonly used in severe cases of osteoarthritis and they can be given orally or by injection. Steroids are used to treat autoimmune forms of arthritis but they should be avoided if you have infectious arthritis. Steroids have multiple side effects, including upset stomach and gastrointestinal bleeding, high blood pressure, thinning of bones, cataracts, and increased infections. The risks are most pronounced when steroids are taken for long periods of time or at high DOSes. Close supervision by a physician is essential.
• Disease-modifying anti-rheumatic drugs -- these have been used traditionally to treat rheumatoid arthritis and other autoimmune causes of arthritis. These drugs include gold salts, penicillamine, sulfasalazine, and hydroxychloroquine. More recently, methotrexate has been shown to slow the progression of rheumatoid arthritis and improve your quality of life. Methotrexate itself can be highly toxic and patients on the medication require frequent blood tests.
• Anti-biologics -- these are the most recent breakthrough for the treatment of rheumatoid arthritis. Such medications, including etanercept (Enbrel), infliximab (Remicade) and adalimumab (Humira), are administered by injection and can dramatically improve your quality of life.
• Immunosuppressants -- these drugs, like azathioprine or cyclophosphamide, are used for serious cases of rheumatoid arthritis when other medications have failed.

It is very important to take your medications as directed by your doctor. If you are having difficulty doing so (for example, due to intolerable side effects), you should talk to your doctor.

Surgery and other treatments

In some cases, surgery may be required to rebuild the joint (arthroplasty) or to replace the joint (such as a total knee joint replacement) to help you maintain a more normal lifestyle. The decision to perform joint replacement surgery is normally made when other alternatives, such as lifestyle changes and medications, are no longer effective.

Normal joints contain a lubricant called "synovial fluid." In joints with arthritis, this fluid is not produced in adequate amounts. One other treatment approach is to inject arthritic joints with a manmade version of the joint fluid, such as hylan G-F 20 (Synvisc), or other hyaluronic acid preparations. This synthetic fluid may postpone the need for surgery at least temporarily and improve the quality of life for arthritis patients. Many studies are evaluating the effectiveness of this type of therapy.
