The Burden of Ulcerative Colitis and Its Clinical Course
Ulcerative colitis (UC) is a chronic, relapsing and remitting inflammatory bowel disease (IBD) that affects the mucosal surface of the colon and rectum.1,2 The inflammation associated with UC begins in the rectum, oftentimes extends proximally in a continuous manner, and is capable of damaging the entire length of the colon.1,2 The reported incidence and prevalence rates of UC in North America range from 2.3 to 15.6 cases per 100,000 person-years and 37.5 to 246 cases per 100,000 people, respectively.While UC typically demonstrates a bimodal distribution with respect to age at onset, UC can present at any age, and there is a slight predominance in males versus females.2,3

Although bloody diarrhea with or without mucus is the hallmark of UC, patients affected by the condition may also present with symptoms such as abdominal discomfort or pain, fecal urgency, and/or tenesmus.2,4 While the onset of UC is often gradual, its clinical course is characterized by alternating periods of spontaneous remission and subsequent relapse, and the disease can progress over time.1,2,4 The unchecked progression of UC can lead to further intestinal complications including bleeding, toxic or fulminant colitis, toxic megacolon, stricture, dysplasia or colorectal cancer, and colectomy. Extra-intestinal manifestations of UC may also occur, including involvement of the musculoskeletal, hepatobiliary, hematopoietic, and/or coagulation systems.2,4
        
Best Practices for Diagnosis and Management of Ulcerative Colitis
UC is typically diagnosed through lower endoscopic studies (eg, colonoscopy) and histological evaluations. These studies and evaluations allow clinicians to determine the severity of inflammation and define the extent of disease, which provides valuable prognostic information and guides treatment strategies.4 UC is classified as mild, moderate, severe, or fulminant, as defined in the Table. The majority of patients have mild or moderate UC.5-8
                   
 
                    
The goals of UC treatment are to induce and maintain remission and to suppress inflammation. To achieve these goals, clinicians have often enlisted the help of various oral, parenteral, and rectal pharmacologic agents, including aminosalicylates, glucocorticoids (GCs), immunosuppressants, and biologic agents that target tumor necrosis factor (TNF)-α.1,2
       
Defining the Role of Glucocorticoids in Ulcerative Colitis
Systemic GCs are widely used for the treatment of mild, moderate, and severe active UC and acute flares of UC.2,9 Systemic GCs have high glucocorticoid (cortisol-like) effects and are often associated with a broad range of adverse reactions that limit their use, such as hypertension, diabetes mellitus, peptic ulcer, glaucoma, and osteoporosis.2,10 To help reduce the risk of complications due to GCs, the American Gastroenterological Association performance measures for IBD recommend that exposure to systemic GCs be limited, and that treatment be shifted to steroid-sparing agents.11 Selecting an oral GC such as budesonide may be preferable because of its topical anti-inflammatory effects and reduced adverse reaction profile due to its extensive first-pass metabolism and low systemic bioavailability.2,12 Furthermore, an orally administered topical GC with targeted drug delivery would potentially reduce systemic exposure, decrease toxicity, and improve efficacy.9,13
          
UCERIS for Ulcerative Colitis

UCERIS (budesonide) extended release tablets is a unique formulation of budesonide, available by prescription only, that is indicated for the induction of remission in patients with active, mild-to-moderate UC, to be taken once daily in the morning by mouth, with or without food, for up to 8 weeks.14 Its unique formulation with multi-matrix technology (MMX) causes pH-dependent dissolution at a pH of 7 or greater, which allows the active drug, budesonide, to undergo a controlled and targeted release throughout the entire length of the colon while limiting systemic absorption.2,14 As a result of the extensive first-pass metabolism (90%) and low systemic bioavailability and the controlled release of budesonide via MMX technology, systemic absorption of budesonide is limited, reducing the likelihood of systemic GC-related adverse reactions.2,12,14  Controlled ileal release budesonide targets the ileum/ascending colon, dissolving at a pH greater than 5.5 (the approximate pH level of the duodenum), and is not indicated for the treatment of UC.15  The clinical effect of this information is unknown.
   
Two randomized, double-blind, placebo-controlled studies were conducted in a total of 899 adult patients with active, mild to moderate UC.14 The rigorous primary end point assessed combined clinical remission and mucosal healing.12,13 With regard to efficacy, in a pooled analysis of data from 2 phase III trials, 3 times more patients who received budesonide MMX (9 mg) achieved clinical remission and mucosal healing versus placebo (18% and 6%, respectively).16 No clinically significant differences were observed with respect to the overall percentages of patients with any glucocorticoid-related effects between UCERIS (9 mg) and placebo after 8 weeks of treatment.14 In a 12-month safety study, the incidence of treatment-related adverse reactions was similar with UCERIS (6 mg) and placebo (21.0% and 21.3% respectively).17 The most common adverse reactions with UCERIS with an incidence of 2% or greater are headache, nausea, decreased blood cortisol, upper abdominal pain, fatigue, flatulence, abdominal distension, acne, urinary tract infection, arthralgia, and constipation.14
          
UCERIS offers a convenient, orally administered, effective, locally acting corticosteroid option with targeted MMX technology for patients with mild to moderate UC, and is supported by a copay assistance program to increase patient accessibility.
