Canasa

What is this medication? Canasa is a prescription medication that contains the active ingredient mesalamine and is primarily used to treat mild to moderate ulcerative proctitis. This condition is a specific form of inflammatory bowel disease that involves inflammation and irritation in the lining of the rectum. Because it is provided as a rectal suppository, the medication works directly at the site of the inflammation to help relieve symptoms such as rectal bleeding, pain, and the frequent urge to have a bowel movement.

The drug belongs to a class of medications known as aminosalicylates, which are designed to reduce swelling and tissue damage in the digestive tract. It is typically prescribed to be used once daily at bedtime, allowing the medication to remain in the rectum for several hours to achieve maximum effectiveness. By controlling the underlying inflammation, this treatment helps patients manage their flare-ups and work toward maintaining remission of their symptoms.
