The diagnosis is therefore based on identifying a cluster of clinical symptoms that are consistent with the disorder and excluding other conditions by looking for clinical alert signs and performing limited diagnostic testing cheap 500mg amoxil mastercard top antibiotics for acne. Since the pathophysiological mechanisms underlying the disorder are not known buy 500 mg amoxil free shipping antibiotics for uti safe for pregnancy, the current approach to management is based primarily on the patients’ predominant symptoms and overall wellbeing rather than on a specific underlying etiological mechanism. The specific treatment is determined by whether pain, diarrhea, or constipation is predominant and the targeted symptom is treated using the same medications as in other conditions. For example, symptom/s of constipation associated with IBS (i. Since the treatment of constipation symptoms is similar in the two conditions, we reviewed and included clinical trials related to constipation symptoms in these two conditions (IBS-C and chronic constipation). Functional constipation is considered one of a group of five functional bowel disorders defined by the Rome III classification system (developed by multinational working teams known as the Rome 8 Committees). As a functional disorder, constipation can stand on its own as a distinct diagnosis of functional constipation or be part of another functional bowel disorder of IBS. IBS is the most common Constipation Drugs Page 6 of 141 Final Report Drug Effectiveness Review Project functional gastrointestinal disorder. It is defined as a combination of chronic or recurrent gastrointestinal symptoms, not explained by structural or biochemical abnormalities. The diagnosis is based on identifying typifying symptoms, using of symptom-based diagnostic criteria, and limited diagnostic tests to exclude other conditions. In order to meet the criteria patients must have abdominal pain or discomfort associated with alterations in stool frequency, form, and passage. IBS is sub-classified as diarrhea-predominant (IBS-D), constipation-predominant (IBS-C), or mixed (combination of both), depending on the most prevalent bowel pattern. However, because the predominant symptom often changes over time, it is not uncommon 9 for a patient to alternate between these IBS subgroups. This report focuses on functional constipation and does not cover other IBS associated symptoms such as abdominal pain/discomfort, diarrhea, and bloating. The disorder may be secondary to systemic diseases (e. Another common etiology is the use of prescription or over the counter (OTC) medications that slow down the intestinal transit (Table 2). Chronic primary or idiopathic constipation is primarily a diagnosis of exclusion which is made when the other possible etiologies have been ruled out. Once primary idiopathic constipation has been diagnosed and “red flags” suggesting other serious diseases such as colon or rectal cancer have been eliminated, empiric treatment may be started with an appropriate follow-up to assess the response. Medications associated with constipation Prescription Over the counter (OTC) Opiates Antacids, especially calcium containing Anticholinergics Calcium supplements Tricyclic antidepressants Iron supplements Calcium channel blockers Antidiarrheal agents Antiparkinsonian drugs NSAIDS Sympathomimetics Antipsychotics Diuretics Antihistamines Constipation Drugs Page 7 of 141 Final Report Drug Effectiveness Review Project Approach to Management I. Initial recommendations In clinical practice patients with milder symptoms are usually offered behavioral, diet and lifestyle modifications as the first step of treatment. Despite the lack of controlled clinical trials to support these recommendations patients are often encouraged to increase their fluid intake, get involved with moderate increase in exercise, and use the bathroom daily in response to feeling of urge for a bowel movement or at a specific time, particularly after meals. Patients with more severe symptoms or those who do not respond to this initial treatment are usually offered an empiric medication treatment with fiber supplements and “simple laxatives. Evaluation of chronic primary constipation The initial evaluation is based on careful history and physical evaluation. Important historical features include bowel frequency, stool consistency, need for straining, and feeling of incomplete evacuation. Presence of abdominal pain/discomfort can suggest a diagnosis of other functional disorders (e. Patients’ medications should be reviewed carefully and initial limited laboratory tests should be performed to exclude medications (e. The majority of patients with constipation are seen by primary care physicians. Those who are more difficult-to-manage or fail to respond to the initial medical therapy are referred to GI specialists or tertiary care centers. In these settings, patients with primary constipation can be further evaluated for the underlying pathophysiological mechanism(s) of their constipation. Using functional tests of the colon and anorectum, primary constipation can be divided into three separate subgroups: 1.
