5-Aminosalicylic acid (5-ASA) is a medication commonly used to treat inflammatory bowel disease (IBD), including ulcerative colitis and Crohn's disease. It is also used to treat rheumatoid arthritis and psoriatic arthritis. 5-ASA works by reducing inflammation in the body, particularly in the digestive tract and joints.

5-ASA is available in various forms, including tablets, suppositories, and enemas. The most common form is mesalamine, a prodrug that is converted to 5-ASA in the body. Other forms include olsalazine and balsalazide, which are combinations of 5-ASA with other drugs.

5-ASA is generally well-tolerated, but it can cause side effects such as abdominal pain, diarrhea, and nausea. It may also interact with other medications, so it is important to consult a healthcare provider before starting treatment.

5-ASA is typically taken orally or rectally, depending on the condition being treated. The dosage and duration of treatment vary depending on the individual and the specific condition. Regular monitoring by a healthcare provider is essential to ensure the medication is effective and to manage any potential side effects.

5-ASA is considered a first-line treatment for mild to moderate ulcerative colitis and Crohn's disease. It is also used as a second-line treatment for rheumatoid arthritis and psoriatic arthritis. The exact mechanism of action of 5-ASA is not fully understood, but it is believed to work by inhibiting the production of inflammatory mediators in the body.
