Sensory Properties of Bowel Cleansing Solutions

Samples of 4 commercially available bowel cleansing solutions, namely PEG-electrolyte + ascorbic acid (PEG-Asc, Moviprep®, Norgine, UK), PEG-electrolyte (PEG, Fortrans® Ibsen, France), sodium picosulfate/magnesium citrate (SPS, Picoprep®, Ferring, Switzerland), and oral sodium sulfate (OSS, Izinova®, Ibsen, France) were prepared according to the manufacturer's instructions. Descriptive analysis was conducted with trained panelists (N= 14) to create a sensory profile for the solutions and generated attributes were rated on an unstructured 15-cm line scale using the Compusense at-hand® (Guelph, Canada) sensory evaluation software. Acceptability testing was carried out with untrained participants (N=80) and samples were rated on the 9-point hedonic scale. Moreover, a Just-About-Right (JAR) scale was included for the four basic tastes to determine their compatibility with optimum taste/acceptability levels in the products.

Medical and Biotech [MESH] Definitions

A diphenylmethane stimulant laxative used for the treatment of constipation and for bowel evacuation. (From Martindale, The Extra Pharmacopoeia, 30th ed, p871)

Solutions for rinsing the mouth, possessing cleansing, germicidal, or palliative properties. (From Boucher's Clinical Dental Terminology, 4th ed)

A white, crystalline powder that is commonly used as a pH buffering agent, an electrolyte replenisher, systemic alkalizer and in topical cleansing solutions.

A condition due to decreased dietary intake of potassium, as in starvation or failure to administer in intravenous solutions, or to gastrointestinal loss in diarrhea, chronic laxative abuse, vomiting, gastric suction, or bowel diversion. Severe potassium deficiency may produce muscular weakness and lead to paralysis and respiratory failure. Muscular malfunction may result in hypoventilation, paralytic ileus, hypotension, muscle twitches, tetany, and rhabomyolysis. Nephropathy from potassium deficit impairs the concentrating mechanism, producing polyuria and decreased maximal urinary concentrating ability with secondary polydipsia. (Merck Manual, 16th ed)

Sterile solutions, essentially free from foreign particles and suitably compounded and dispensed, for instillation into the eye. It does not include solutions for cleaning eyeglasses or CONTACT LENS SOLUTIONS. (From Dorland, 27th ed)
