Functional Constipation
Functional constipation, known as chronic idiopathic constipation (CIC), is constipation that does not have a physical (anatomical) or physiological (hormonal or other body chemistry) cause. It may have a neurological, psychological or psychosomatic cause. A person with functional constipation may be healthy, yet has difficulty defecating. Symptoms and diagnosis Chronic idiopathic constipation is similar to constipation-predominant irritable bowel syndrome (IBS-C); however, people with CIC do not have other symptoms of IBS, such as abdominal pain. Diagnosing CIC can be difficult as other syndromes must be ruled out as there is no physiological cause for CIC. Doctors will typically look for other symptoms, such as blood in stool, weight loss, low blood count, or other symptoms. To be considered functional constipation, symptoms must be present at least a fourth of the time. Possible causes are: * Anismus * Descending perineum syndrome * Other inability or unwillingness to control ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Constipation
Constipation is a bowel dysfunction that makes bowel movements infrequent or hard to pass. The stool is often hard and dry. Other symptoms may include abdominal pain, bloating, and feeling as if one has not completely passed the bowel movement. Complications from constipation may include hemorrhoids, anal fissure or fecal impaction. The normal frequency of bowel movements in adults is between three per day and three per week. Babies often have three to four bowel movements per day while young children typically have two to three per day. Constipation has many causes. Common causes include slow movement of stool within the colon, irritable bowel syndrome, and pelvic floor disorders. Underlying associated diseases include hypothyroidism, diabetes, Parkinson's disease, celiac disease, non-celiac gluten sensitivity, colon cancer, diverticulitis, and inflammatory bowel disease. Medications associated with constipation include opioids, certain antacids, calcium channel bloc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colon (anatomy)
The large intestine, also known as the large bowel, is the last part of the gastrointestinal tract and of the digestive system in tetrapods. Water is absorbed here and the remaining waste material is stored in the rectum as feces before being removed by defecation. The colon is the longest portion of the large intestine, and the terms are often used interchangeably but most sources define the large intestine as the combination of the cecum, colon, rectum, and anal canal. Some other sources exclude the anal canal. In humans, the large intestine begins in the right iliac region of the pelvis, just at or below the waist, where it is joined to the end of the small intestine at the cecum, via the ileocecal valve. It then continues as the colon ascending the abdomen, across the width of the abdominal cavity as the transverse colon, and then descending to the rectum and its endpoint at the anal canal. Overall, in humans, the large intestine is about long, which is abo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Functional Symptom
A functional symptom is a medical symptom with no known physical cause. In other words, there is no structural or pathologically defined disease to explain the symptom. The use of the term 'functional symptom' does not assume psychogenesis, only that the body is not functioning as expected. Functional symptoms are increasingly viewed within a framework in which 'biological, psychological, interpersonal and healthcare factors' should all be considered to be relevant for determining the aetiology and treatment plans. Historically, there has often been fierce debate about whether certain problems are predominantly related to an abnormality of structure (disease) or are psychosomatic in nature, and what are at one stage posited to be functional symptoms are sometimes later reclassified as organic, as investigative techniques improve. It is well established that psychosomatic symptoms are a real phenomenon, so this potential explanation is often plausible, however the commonality of a ...

Anorectal Manometry
Anorectal manometry (ARM) is a medical test used to measure pressures in the anus and rectum and to assess their function. The test is performed by inserting a catheter, that contains a probe embedded with pressure sensors, through the anus and into the rectum. Patients may be asked to perform certain maneuvers, such as coughing or attempting to defecate, to assess for pressure changes. Anorectal manometry is a safe and low risk procedure. From 2014 to 2018, the international anorectal physiology working group (IAPWG) meet several times to develop consensus on indications for anorectal manometry. Their assessment concluded that anorectal manometry was indicated when used in assessment of fecal incontinence, constipation, evacuation disorders (including Hirschsprung's disease), functional anorectal pain and in the assessment of anorectal function preoperatively or after a traumatic obstetric injury. In addition to the indications outlined by the IAPWG, anorectal manometry has bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plecanatide
Plecanatide, sold under the brand name Trulance, is a medication for the treatment of chronic idiopathic constipation (CIC) and irritable bowel syndrome with constipation. Plecanatide is an agonist of guanylate cyclase-C. Plecanatide increases intestinal transit and fluid through a buildup of cGMP. Medical uses As of January 2017, plecanatide is approved in the United States for the treatment of chronic idiopathic constipation in adults. The presence of this condition is determined using the Rome III diagnostic criteria for chronic constipation which requires that the patient meet stool frequency, stool consistency, incomplete evacuation, and straining requirements in addition to not being a likely candidate for irritable bowel syndrome. The symptoms should also have been present for at least three of the last six months to establish the chronic nature of the condition before treatment with plecanatide is indicated. Plecanatide has been shown to be safe and effective. It has s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sodium Picosulphate
Sodium picosulfate ( INN, also known as sodium picosulphate) is a contact stimulant laxative used as a treatment for constipation or to prepare the large bowel before colonoscopy or surgery. It is sold under the trade names Sodipic Picofast, Laxoberal, Laxoberon, Purg-Odan, Picolax, Guttalax, Namilax, Pico-Salax, PicoPrep, and Prepopik, among others. It is available as a generic medication. Effects Orally administered sodium picosulfate is generally used for thorough evacuation of the bowel, usually for patients who are preparing to undergo a colonoscopy. It takes 12–24 hours to work, since it works in the colon. Abdominal cramps and diarrhea are normal effects of picosulfate and should be expected. The use of sodium picosulfate has also been associated with certain electrolyte disturbances, such as hyponatremia and hypokalemia. Patients are often required to drink large amounts of clear fluids, to compensate for dehydration and to reestablish normal electrolyte balance. ...

Bisacodyl
Bisacodyl (INN) is an organic compound that is used as a stimulant laxative drug. It works directly on the colon to produce a bowel movement. It is typically prescribed for relief of episodic and chronic constipation and for the management of neurogenic bowel dysfunction, as well as part of bowel preparation before medical examinations, such as for a colonoscopy. Bisacodyl is a derivative of triphenylmethane. It was first used as a laxative in 1953 because of its structural similarity to phenolphthalein. It is on the World Health Organization's List of Essential Medicines. Available forms Bisacodyl is marketed under the trade names Dulcolax/Durolax, Muxol, Fleet, Nourilax, Alophen, Correctol, and Carter's Little Pills (formerly Carter's Little Liver Pills), as well as being available generically.

Elobixibat
Elobixibat is an inhibitor of the ileal bile acid transporter (IBAT), undergoing development in clinical trials for the treatment of chronic constipation and irritable bowel syndrome with constipation (IBS-C). Mechanism of action Elobixibat is an inhibitor of IBAT, which is an alternative name for the apical sodium bile acid transporter (ASBT) encoded by the ''SLC10A2'' gene. ASBT/IBAT is a bile acid:sodium symporter responsible for the reuptake of bile acids in the ileum, the initial step in their enterohepatic circulation. By inhibiting the uptake of bile acids, elobixibat increases the bile acid concentration in the gut, and this accelerates intestinal passage and softens the stool. Following several phase II studies, it is now undergoing phase III trials. Drug development The drug was developed by Albireo AB, who licensed it to Ferring Pharmaceuticals for further development and marketing. Albireo has partnered with Ajinomoto is a Japanese multinational food and bio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Velusetrag
Velusetrag (INN, USAN; previously known as TD-5108) is an experimental drug candidate for the treatment of gastric neuromuscular disorders including gastroparesis, and lower gastrointestinal motility disorders including chronic idiopathic constipation and irritable bowel syndrome. It is a potent, selective, high efficacy 5-HT4 receptor serotonin agonist being developed by Theravance Biopharma and Alfa Wassermann. Velusetrag demonstrates less selectivity for other serotonin receptors, such as 5-HT2 and 5-HT3, to earlier generation 5-HT agonists like cisapride and tegaserod. In a large clinical trial in patients with chronic idiopathic constipation (n=401), velusetrag statistically and clinically improved the frequency and consistency of complete spontaneous bowel movements (CSBMs) compared to placebo. Doses of 15 and 30 mg were well tolerated compared to placebo. Velusetrag showed accelerated intestinal and colonic transit after single dosing and accelerated gastric empty ...

Tegaserod
Tegaserod is a 5-HT4 agonist manufactured by Novartis and sold under the names Zelnorm and Zelmac for the management of irritable bowel syndrome and constipation. Approved by the FDA in 2002, it was subsequently removed from the market in 2007 due to FDA concerns about possible adverse cardiovascular effects. Before then, it was the only drug approved by the United States Food and Drug Administration to help relieve the abdominal discomfort, bloating, and constipation associated with irritable bowel syndrome. Its use was also approved to treat chronic idiopathic constipation. Mechanism of action The drug functions as a motility stimulant, achieving its desired therapeutic effects through activation of the 5-HT4 receptors of the enteric nervous system in the gastrointestinal tract. It also stimulates gastrointestinal motility and the peristaltic reflex, and allegedly reduces abdominal pain. Additionally, tegaserod is a 5-HT2B receptor antagonist.
