Clinical Summary

A XANTHINE OXIDASE inhibitor that decreases URIC ACID production. It also acts as an antimetabolite on some simpler organisms.

Therapeutic Applications

Allopurinol is used to treat gout and certain types of kidney stones. It is also used to prevent increased uric acid levels in patients receiving cancer chemotherapy. These patients can have increased uric acid levels due to release of uric acid from the dying cancer cells. Allopurinol works by reducing the amount of uric acid made by the body. Increased uric acid levels can cause gout and kidney problems.

Clinical Summary

An immunosuppressive agent used in combination with cyclophosphamide and hydroxychloroquine in the treatment of rheumatoid arthritis. According to the Fourth Annual Report on Carcinogens (NTP 85-002, 1985), this substance has been listed as a known carcinogen. (Merck Index, 11th ed)

Therapeutic Applications

Azathioprine is used to prevent organ rejection in people who have received a kidney transplant. It is usually taken along with other medications to allow your new kidney to function normally. Azathioprine is also used to treat rheumatoid arthritis. In this condition, the body's defense system (immune system) attacks healthy joints. Azathioprine belongs to a class of drugs known as immunosuppressants. It works by weakening the immune system to help your body accept the new kidney as if it were your own (in the case of an organ transplant) or to prevent further damage to your joints (in the case of rheumatoid arthritis). Talk to your doctor about the risks and benefits of azathioprine, especially when used by children and young adults.

Clinical Summary

A pyrazole derivative and selective CYCLOOXYGENASE 2 INHIBITOR that is used to treat symptoms associated with RHEUMATOID ARTHRITIS; OSTEOARTHRITIS and JUVENILE ARTHRITIS, as well as the management of ACUTE PAIN.

Therapeutic Applications

This medication is a nonsteroidal anti-inflammatory drug (NSAID), specifically a COX-2 inhibitor, which relieves pain and swelling (inflammation). It is used to treat arthritis, acute pain, and menstrual pain and discomfort. The pain and swelling relief provided by this medication helps you perform more of your normal daily activities. If you are treating a chronic condition such as arthritis, ask your doctor about non-drug treatments and/or using other medications to treat your pain. See also Warning section. This drug works by blocking the enzyme in your body that makes prostaglandins. Decreasing prostaglandins helps to reduce pain and swelling.

Clinical Summary

A major alkaloid from Colchicum autumnale L. and found also in other Colchicum species. Its primary therapeutic use is in the treatment of gout, but it has been used also in the therapy of familial Mediterranean fever (PERIODIC DISEASE).

Therapeutic Applications

This medication is used to prevent or treat gout attacks (flares). Usually gout symptoms develop suddenly and involve only one or a few joints. The big toe, knee, or ankle joints are most often affected. Gout is caused by too much uric acid in the blood. When uric acid levels in the blood are too high, the uric acid may form hard crystals in your joints. Colchicine works by decreasing swelling and lessening the build up of uric acid crystals that cause pain in the affected joint(s). This medication is also used to prevent attacks of pain in the abdomen, chest, or joints caused by a certain inherited disease (familial Mediterranean fever). It is thought to work by decreasing your body's production of a certain protein (amyloid A) that builds up in people with familial Mediterranean fever. Colchicine is not a pain medication and should not be used to relieve other causes of pain.

Clinical Summary

A recombinant version of soluble human TNF receptor fused to an IgG FC fragment that binds specifically to TUMOR NECROSIS FACTOR and inhibits its binding with endogenous TNF receptors. It prevents the inflammatory effect of TNF and is used to treat RHEUMATOID ARTHRITIS; PSORIATIC ARTHRITIS and ANKYLOSING SPONDYLITIS.

Therapeutic Applications

This medication is used alone or in combination with an immunosuppressant (such as methotrexate) to treat certain types of arthritis (such as rheumatoid, psoriatic, juvenile idiopathic, and ankylosing spondylitis). Some brands of this medication are also used to treat a skin condition called psoriasis. These conditions are caused by an overactive immune system (autoimmune disease). The immune system attacks the body's own healthy cells, causing inflammation in the joints and skin. Etanercept controls your body's defensive response by blocking the action of a certain natural substance (TNF) that is used by the immune system. Treatment decreases redness, itching and scaly patches in psoriasis as well as the pain, swelling and stiffness of joints in arthritis. This medication can stop the progression of disease and joint damage, resulting in improved daily functioning and quality of life. This medication treats but does not cure autoimmune diseases. Symptoms usually return within 1 month of stopping the medication.

Clinical Summary

A member of the vitamin B family that stimulates the hematopoietic system. It is present in the liver and kidney and is found in mushrooms, spinach, yeast, green leaves, and grasses (POACEAE). Folic acid is used in the treatment and prevention of folate deficiencies and megaloblastic anemia.

Therapeutic Applications

Folic acid is the man-made form of folate. Folate is a B-vitamin naturally found in some foods. It is needed to form healthy cells, especially red blood cells. Folic acid supplements may come in different forms (such as L-methylfolate, levomefolate, methyltetrahydrofolate). They are used to treat or prevent low folate levels. Low folate levels can lead to certain types of anemia. Conditions that can cause low folate levels include poor diet, pregnancy, alcoholism, liver disease, certain stomach/intestinal problems, kidney dialysis, among others. Women of childbearing age should receive adequate amounts of folic acid either through their diet or supplements to prevent infant spinal cord birth defects.

Clinical Summary

A humanized monoclonal antibody that binds specifically to TNF-ALPHA and blocks its interaction with endogenous TNF RECEPTORS to modulate INFLAMMATION. It is used in the treatment of RHEUMATOID ARTHRITIS; PSORIATIC ARTHRITIS; CROHN'S DISEASE and ULCERATIVE COLITIS.

Therapeutic Applications

Adalimumab is used to reduce pain and swelling due to certain types of arthritis (such as rheumatoid, psoriatic, juvenile idiopathic, ankylosing spondylitis). This medication is also used to treat certain skin disorders (such as plaque-type psoriasis, hidradenitis suppurativa). It works by blocking a protein (tumor necrosis factor or TNF) found in the body's immune system that causes joint swelling and damage in arthritis as well as red scaly patches in psoriasis. Adalimumab belongs to a class of drugs known as TNF blockers. By reducing joint swelling, this medication helps to reduce further joint damage and preserve joint function. Adalimumab is also used to treat certain bowel conditions (Crohn's disease, ulcerative colitis) and a certain eye disease (uveitis).

Clinical Summary

A drug that is used in the management of inflammatory bowel diseases. Its activity is generally considered to lie in its metabolic breakdown product, 5-aminosalicylic acid (see MESALAMINE) released in the colon. (From Martindale, The Extra Pharmacopoeia, 30th ed, p907)

Therapeutic Applications

Sulfasalazine is used to treat a certain type of bowel disease called ulcerative colitis. This medication does not cure this condition, but it helps decrease symptoms such as fever, stomach pain, diarrhea, and rectal bleeding. After an attack is treated, sulfasalazine is also used to increase the amount of time between attacks. This medication works by reducing irritation and swelling in the large intestines. In addition, delayed-release tablets of sulfasalazine are used to treat rheumatoid arthritis. Sulfasalazine helps to reduce joint pain, swelling, and stiffness. Early treatment of rheumatoid arthritis with sulfasalazine helps to reduce/prevent further joint damage so you can do more of your normal daily activities. This medication is used with other drugs, rest, and physical therapy in patients who have not responded to other medications (salicylates, nonsteroidal anti-inflammatory drugs-NSAIDs).
