HOW DO 5-AMINOSALICYLIC ACID DERIVATIVES WORK?
5-aminosalicylic acid derivatives are a class of drugs used to treat active ulcerative colitis (a condition which causes swelling and sores in the lining of the colon [large intestine] and rectum), mild-to-moderate Crohn's disease (a chronic inflammatory disease of the intestines, especially the colon and ileum, associated with ulcers and fistulae), and ulcerative proctitis (a mild form of ulcerative colitis).
They are also indicated to reduce inflammation and pain in rheumatoid arthritis (a chronic progressive disease, causing inflammation in the joints resulting in painful deformity and immobility) and to treat tuberculosis in combination with other active antitubercular medications.
Inflammatory diseases cause excessive production of chemicals such as “prostaglandins” (produced by the enzymes, cyclooxygenase, and lipoxygenase) responsible for inflammation in the colon. 5-aminosalicylic acid derivatives work by blocking the activity of cyclooxygenase and lipoxygenase, thereby reducing the production of prostaglandins.
5-aminosalicylic acid derivatives are anti-inflammatory drugs that help to reduce symptoms of ulcerative colitis such as diarrhea, rectal bleeding, and stomach pain.
5-aminosalicylic acid derivatives are administered via the oral route, typically three times a day with or without food, and as a suppository and an enema to be used in the rectum typically once a day at bedtime.
5-aminosalicylic acid derivatives work in the following ways:
- They belong to a class of drugs called “aminosalicylates” that work by reducing bowel inflammation.
- In addition, they are antituberculosis antibiotic that works by stopping or slowing the growth of bacteria.
