What is misoprostol? What are the uses for misoprostol?
Misoprostol is a synthetic (man-made) prostaglandin that is used to reduce the risk of stomach ulcers in patients treated with nonsteroidal anti-inflammatory drugs (NSAIDs, for example, aspirin, ibuprofen, etc.) that are used for pain and various inflammatory conditions, for example, arthritis. Misoprostol is used primarily in patients at high risk for stomach ulcers when treated with NSAIDs, for example, the elderly, patients with concomitant debilitating diseases, and patients with a history of ulcers. Prostaglandins are chemicals that are made within many organs of the body including the stomach. In the stomach, prostaglandins are believed to protect the inner lining of the stomach from the ulcer-producing effects of NSAIDs. Scientists now believe that NSAIDs produce ulceration by preventing the production of prostaglandins in the stomach. Synthetic prostaglandins such as misoprostol given orally "replace" the prostaglandins whose production is inhibited by NSAIDs and have been shown to protect the lining of the stomach from NSAID-induced ulcers. Misoprostol was approved by the FDA in December 1988.

Lupus can cause disease of the skin, heart, lungs, kidneys, joints, and nervous system. When only the skin is involved, the condition is called discoid lupus. When internal organs are involved, the condition is called systemic lupus erythematosus (SLE).
Arthritis (Joint Inflammation)
Arthritis is inflammation of one or more joints. When joints are inflamed they can develop stiffness, warmth, swelling, redness and pain. There are over 100 types of arthritis, including osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, lupus, gout, and pseudogout.
Pain management and treatment can be simple or complex, according to its cause. There are two basic types of pain, nociceptive pain and neuropathic pain. Some causes of neuropathic pain include: complex regional pain syndrome, interstitial cystitis, and irritable bowel syndrome. There are a variety of methods to treat chronic pain, which are dependant on the type of pain experienced.
Nonsteroidal Anti-inflammatory Drugs and Ulcers
Nonsteroidal anti-inflammatory drugs (NSAIDs) are prescribed medications for the treatment of inflammatory conditions. Examples of NSAIDs include aspirin, ibuprofen, naproxen, and more. One common side effect of NSAIDs is peptic ulcer (ulcers of the esophagus, stomach, or duodenum). Side effects, drug interactions, warnings and precautions, and patient safety information should be reviewed prior to taking NSAIDs.
Chronic pain is pain (an unpleasant sense of discomfort) that persists or progresses over a long period of time. In contrast to acute pain that arises suddenly in response to a specific injury and is usually treatable, chronic pain persists over time and is often resistant to medical treatments.
