Picosulfate

Bisacodyl, sodium picosulfate and their metabolite bis-(p-hydroxyphenyl)-pyridyl-2-methane (BHPM) are clinically used to treat constipation. In this study, with the rational hapten design, a broad-specific and highly sensitive monoclonal antibody (mAb) was obtained with half of inhibitory concentrations of 0.16, 0.18 and 0.65 ng/mL for bisacodyl, sodium picosulfate and BHPM, respectively. Based on this mAb, a rapid and sensitive lateral flow immunochromatographic assay toward bisacodyl, sodium picosulfate and BHPM in slimming foods was developed...

Chronic constipation is a common gastrointestinal condition, and most individuals self-treat with multiple over-the-counter (OTC) laxatives prior to consulting a health care provider. This brief report is a synopsis of an updated systematic review the authors conducted of published data on the efficacy and safety of OTC treatments to provide evidence-based recommendations. After applying the selection criteria, 41 randomized controlled clinical trials of ≥ 4-week duration were identified and analyzed...

This prospective, randomized and double-blind study aims to compare two different protocols used for bowel preparation in patients scheduled for colonoscopy. The protocols were composed by solutions of Mannitol or sodium picosulfate combined with magnesium oxide. Patients from the proctology outpatient clinic of the General Surgery Unit of the Regional Hospital of Asa Norte (HRAN) comprised the sample of this study. Both the patients and the colonoscopist had no prior knowledge of the substance used to prepare bowel, which was randomly distributed among the participants...

Objective: To evaluate patient acceptability and bowel preparation efficacy of sodium picosulfate-magnesium citrate (PICOPREP) for colonoscopy. Methods: A questionnaire survey regarding the patient acceptability of bowel preparation agent PICOPREP was administered to 54 patients, and its efficacy was evaluated using the Ottawa Bowel Preparation Scale (OBPS). Results: Eighteen (33.3%) participants reported that PICOPREP is very easy to drink, 30 (55...

Currently, the same-day polyethylene glycol-electrolyte lavage solution (PEG-ELS) regimen is particularly recommended for afternoon colonoscopy as an alternative to the split-dose regimen in western countries. However, in Japan, the split-dose regimen has never been used as a standard colonoscopy preparation regimen. The aim of this study was to compare the efficacy and tolerability of split-dose PEG containing ascorbic acid (ASC) with same-day single dose PEG-ASC in Japan.This was a single-blinded, non-inferiority, two-center, randomized, controlled study...

BACKGROUND: Ischemic colitis is an adverse event which may occur during bowel preparation for colonoscopy. This study aims to clarify both the incidence and the risk factors of this complication. METHODS: This was a single-center, retrospective, observational study. All outpatients who were prescribed standardized preparation drugs for colonoscopy at the Kyoto Second Red Cross Hospital between November 2011 and March 2020 were included in the study. A split bowel preparation was carried out as follows; magnesium citrate with or without sodium picosulfate hydrate was/were used as a preparation drug on the day before the colonoscopy, and polyethylene glycol electrolyte solution or sodium phosphate was used on the morning of the endoscopic procedure...

INTRODUCTION: an adequate bowel preparation is essential for good mucosal inspection during colonoscopy. This study aims to compare the efficacy of two validated oral lavage solutions for colonoscopy preparation in African patients. METHODS: a prospective observational study of patients undergoing colonoscopy in a referral endoscopy facility in Port Harcourt, Nigeria, using sodium picosulfate magnesium citrate (SPMC) and 4L split-dose polyethylene glycol (PEG). Variables collated were sociodemographic, primary indication, comorbidities, Aronchick bowel preparation scale, polyp/adenoma detection, caecal intubation and outcome...

BACKGROUND: Sodium picosulfate/magnesium citrate (SPMC) is a small-volume bowel cleansing agent with similar efficacy to and better tolerability than polyethylene glycol. However, we found no data on which SPMC preparation (same-day vs. split-dose) provides better bowel cleansing efficacy for afternoon colonoscopy. AIMS: To compare bowel cleansing efficacy of different timing of the regimen. METHODS: This randomized, single-center, endoscopist-blinded, noninferior study compared same-day and split-dose SPMC preparations for afternoon colonoscopy in 101 and 96 patients, respectively...

The antidiarrheal effect of methanolic extract of Trillium govanianum Wall. ex D. Don (Melanthiaceae alt . Trilliaceae) was studied at doses of 12.5, 25, and 50 mg/kg in different animal models of diarrhea including castor oil (6 mL/kg), magnesium sulfate (2 gm/kg), sodium picosulfate (2 mL/kg) and lactitol (0.25 mL/kg). The antispasmodic effect of T. govanianum was studied on isolated rabbit's jejunum, using acetylcholine as tissue stabiliser and verapamil as calcium channel blocker. T. govanianum attenuated the diarrhea by producing a significant decrease in the number and weight of stool, and an increase in stool latency time...

BACKGROUND AND AIM: Post-marketing studies comparing low-volume polyethylene glycol (PEG)-based regimens are limited. This randomized study aimed to compare the efficacy and tolerability of a novel 1-L low-volume PEG-based preparation: 1 L PEG+Asc (PEG3350, sodium ascorbate, sodium sulfate, ascorbic acid, sodium chloride, and potassium chloride) with PEG+SPMC (PEG3350, sodium chloride, potassium chloride and sodium sulfate, sodium picosulfate, magnesium oxide, citric acid, and aspartame), prior to routine colonoscopy at an Australian tertiary referral center...

The development of new capsules now allows endoscopic diagnosis in all segments of the gastrointestinal tract and comes with new needs for differentiated preparation regimens. Although the literature is steadily increasing, the results of the conducted trials on preparation are sometimes conflicting. The ingestion of simethicone before gastric and small bowel capsule endoscopy for prevention of air bubbles is established. The value of a lavage before small bowel capsule endoscopy (SBCE) is recommended, although not supported by all studies...

We report a case of ultrashort-segment Hirschsprung's disease (HD) involving a 4-year-old girl. She was born at 29 weeks gestation from a twin pregnancy. She weighed 1013 g. After birth, she received glycerin enemas and sodium picosulfate hydrate to facilitate defecation. She passed stool once every 4-5 days. When she was 4 years old, she was medicated with polyethylene glycol electrolyte solution. After she drank the solution twice, the abdomen distended rapidly without passage of stool. An abdominal X-ray showed a stored stool mass and a barium enema study revealed dilatation from the rectum to the sigmoid colon due to the stool mass...

BACKGROUND: The effectiveness and safety of colonoscopy are directly dependent on the quality of bowel preparation. Multiple risk factors for inadequate bowel preparation (IBP) have been identified; however, IBP is still reported in 20-30% of cases in most studies. We aimed to identify modifiable predictors of the adequacy of bowel preparation using sodium picosulfate, and to recommend easily modifiable parameters to increase the success rate of colonoscopies. METHODS: This was a single-center observational study of adult outpatients referred for an elective colonoscopy...

BACKGROUND: Adequate bowel preparation is essential for the visualization of the colonic mucosa during colonoscopy. However, the rate of inadequate bowel preparation is still high, ranging from 18% to 35%; this may lead to a higher risk of missing clinically relevant lesions, procedural difficulties, prolonged procedural time, an increased number of interval colorectal carcinomas, and additional health care costs. OBJECTIVE: The aims of this study are to compare bowel preparation instructions provided via a personalized smartphone app (Prepit, Ferring B V) with regular written instructions for bowel preparation to improve bowel preparation quality and to evaluate patient satisfaction with the bowel preparation procedure...

BACKGROUND: Selecting a bowel preparation for patients with renal impairment or diabetes requires special consideration. We aimed to describe the effect of baseline renal impairment or diabetes on the safety, efficacy, and tolerability of low-volume sodium picosulfate, magnesium oxide, and citric acid (SPMC) ready-to-drink oral solution bowel preparation. METHODS: A post hoc secondary analysis was performed from a randomized, assessor-blinded study of SPMC oral solution bowel preparation in participants with mild or moderate baseline renal impairment or diabetes...

BACKGROUND: Research data from patient reports indicate that the least bearable part of colonoscopy is the administration of laxatives for bowel preparation. AIM: To observe the intestinal cleansing efficacy and safety of sodium picosulfate/magnesium citrate and to discuss the patients' experiences due to the procedure. METHODS: Subjects hospitalized in the International Medical Center Ward of Peking University International Hospital, Beijing, China, from April 29 to October 29, 2020, for whom the colonoscopy was planned, were enrolled...

BACKGROUND AND AIMS: High-quality bowel preparation is paramount for the diagnostic accuracy and safety of colonoscopy; however, it is often difficult for patients to adhere to high-volume laxatives, which may contribute to poor bowel preparation. This review aims to assess the efficacy of bowel preparation fluids of 1 L or less (≤1 L). METHODS: We performed a systematic review including all relevant randomized controlled trials on ultra-low volume (≤1 L) bowel preparation fluids for colonoscopy published since 2015...

Background Colonoscopy is the method of choice to evaluate colonic mucosa and the distal ileum, allowing the diagnosis and treatment of many diseases. Appropriate bowel preparation necessitates the use of laxative medications, preferentially by oral administration. These include polyethylene glycol (PEG), sodium picosulfate, and sodium phosphate (NaP). Lactulose, a semi-synthetic derivative of lactose, undergoes fermentation, acidifying the gut environment, stimulates intestinal motility, and increases osmotic pressure within the lumen of the colon...

BACKGROUND AND AIM: Elobixibat is a novel ileal bile acid transporter inhibitor. This study aimed to compare the efficacy, tolerability, and safety of the combination of elobixibat and 1 L of polyethylene glycol formulation containing ascorbic acid (PEG-Asc) solution versus the combination of sodium picosulfate and 1-L PEG-Asc solution as bowel preparation for colonoscopy. METHODS: This multi-center, randomized, observer-blinded, non-inferiority study recruited 210 outpatients who were assigned to either the elobixibat plus 1-L PEG-Asc group (group A) or the sodium picosulfate plus 1-L PEG-Asc group (group B)...

BACKGROUND AND AIMS: Adequate bowel preparation is essential for successful and effective colonoscopy. Several types of cleansing agents are currently available including low-volume solutions. The aim of this study was to compare the efficacy of four different bowel cleansing agents. METHODS: A single-center, prospective, randomized, and single-blind study was performed. Consecutive patients referred for colonoscopy were enrolled and randomized into one of the following types of laxatives: polyethylenglycol 4L (PEG), oral sulfate solution (OSS), 2L polyethylenglycol + ascorbate (2L-PEG/Asc), or magnesium citrate + sodium picosulfate (MCSP)...
