The treatment of ulcerative proctitis depends on the extent of active disease, such as the severity of inflammation and the number of flare-ups you have had. Because ulcerative proctitis affects only the rectum, medications used to treat this disease are usually applied through the anus and directly to the rectum, as suppositories, enemas, or foams. If the inflammation becomes more severe, oral medications may also be prescribed by your physician. Ulcerative proctitis is a form of ulcerative colitis that affects only the rectum.
Medications used to treat ulcerative proctitis work by reducing inflammation.
The two main types of medication are:
These are anti-inflammatory medications such as mesalamine and sulfasalazine. The use of 5-ASA as rectal suppositories, such as CANASA® 1000 mg, is usually the first step in treating active ulcerative proctitis. Inserted into the rectum, 5-ASA suppositories are able to work directly on the area involved. Enemas with 5-ASA can also be used. Rectally administered medications have been shown to be the most rapid and effective way to treat ulcerative proctitis.1
These may include prednisone and hydrocortisone. Corticosteroids are also often used rectally as enemas or foam and can be used alone or along with 5-ASA. When inflammation is severe, corticosteroids are sometimes given in oral or intravenous forms.1
