Although some endoscopy centers recommend the use of a split-dose administration of a 2-L homemade solution of Gatorade plus PEG-3350 (Miralax), a meta-analysis has found this regimen to be inferior to standard, split-dose

4-L PEG solutions.39 Two low-volume hyperosmolar solutions that do not contain PEG are available, but both must be taken with sufficient amounts of water to promote adequate cleansing. These solutions include a sulfate solution (Suprep, 3 L, including water) and a magnesium citrate/picosulfate solution (Prepopik, 2.2 L, including water). Because these hyperosmolar solutions may Alectinib cause dehydration and electrolyte shifts, they should be used with caution in patients with significant renal or cardiac disease or in patients unable or unlikely to comply with instructions. There are no controlled trials comparing split dosing of low-volume, hyperosmolar solutions and split dosing of standard large-volume 4-L PEG solutions, and hence, it is unknown whether these low-volume options provide comparable outcomes. A trial48 comparing split dosing of a low-volume sulfate-based preparation with split dosing of a low-volume (2 L) PEG solution containing ascorbic acid (MoviPrep) yielded a comparable proportion of good or excellent preparations. Most recently, another

preparation selleck chemical (Suclear) has become available, in which a sulfate solution (1 L, including water) is administered the evening before the procedure, and balanced PEG solution (2 L) is administered 4 hours before the procedure. In a controlled trial, split dosing of the sulfate/PEG formulation achieved a similar level of acceptable bowel preparation as split dosing of a low-volume (2 L) PEG/ascorbic acid solution.49 Phosphate-based preparations (tablets and solutions) are still available

but have significant potential for adverse consequences. These preparations Dapagliflozin can induce mucosal ulcerations that mimic IBD, confusing disease diagnosis and staging. More importantly, several reported cases of severe hyperphosphatemia have occurred (some complicated by mortality) as well as cases of acute phosphate nephropathy. Because of safety concerns as well as the availability of numerous alternative preparation options, phosphate-based solutions should be avoided.50 No studies have compared specific preparation types in patients with IBD. Thus, physicians and endoscopy centers may favor particular agents based on personal experience, reported patient satisfaction, and cost considerations. Based on the extensive body of literature supporting their efficacy and safety, bowel regimens with a split-dose of a full-volume (4 L) balanced PEG solution may be recommended for most patients. The European Society of Gastrointestinal Endoscopy51 specifically recommends use of a PEG formulation in patients with IBD, because alternative formulations can cause mucosal damage.
