What is Ulcerative Colitis?

Ulcerative colitis is a chronic inflammation of the large intestine (colon). The colon is the part of the digestive system where waste material is stored. The rectum is the end of the colon adjacent to the anus. In patients with ulcerative colitis, ulcers and inflammation of the inner lining of the colon lead to symptoms of abdominal pain, diarrhea, and rectal bleeding.

Ulcerative colitis is closely related to another condition of inflammation of the intestines called Crohn's disease. Together, they are frequently referred to as inflammatory bowel disease (IBD). Ulcerative colitis and Crohn's diseases are chronic conditions that can last years to decades. They affect approximately 500,000 to 2 million people In the United States. Men and women are affected equally. They most commonly begin during adolescence and early adulthood, but they also can begin during childhood and later in life.

Asacol (mesalamine delayed-release tablets) is used to treat ulcerative colitis, proctitis, and proctosigmoiditis, and is also used to prevent the symptoms of ulcerative colitis from recurring. It is an anti-inflammatory drug. Common side effects include mild nausea, vomiting, stomach cramps, diarrhea, gas, fever, sore throat, flu-like symptoms, constipation, headache or dizziness, tired feeling, or skin rash.

For the treatment of mildly to moderately active ulcerative colitis the usual adult dosage of Asacol is two 400-mg tablets to be taken three times a day for a total daily dose of 2.4 grams for a duration of 6 weeks. For the maintenance of remission of ulcerative colitis the recommended dosage in adults is 1.6 grams daily, in divided doses. Treatment duration is usually 6 months. Asacol may interact with azathioprine or mercaptopurine, pentamidine, tacrolimus, amphotericin B, antibiotics, antiviral medicines, cancer medicine, or aspirin or other NSAIDs (non-steroidal anti-inflammatory drugs).
