Real-life conditions of use of sodium phosphate tablets for colon cleansing before colonoscopy.

ABSTRACT: The purpose of this study was to describe the real-life conditions of use, efficacy, safety, and acceptability of sodium phosphate (NaP) tablets for colon cleansing in routine medical practice in France.A total of 996 patients undergoing bowel preparation were enrolled by 108 gastroenterologists in this observational, longitudinal, prospective, multicenter study. The conditions of use of NaP tablets were assessed with a composite endpoint, which included six criteria for patient compliance with the recommended administration scheme and a criterion for the absence of contraindications to NaP use.Adequate use of NaP was reported for 75.1 % of the patients. The main reasons for misuse were a smaller fluid intake than expected with a dose of 4 tablets and noncompliance with age-related contraindications. The quality of cleansing was satisfactory: the Boston Bowel Preparation Scale (BBPS) total score was 7 or higher in 75.4 % of the patients. Gastroscopy associated with colonoscopy in 38.9 % of the patients revealed gastric lesions, which were considered as possibly related to the use of NaP tablets in 10.3 % of them. Vomiting occurred in 9.8 % of the patients, and 0.6 % discontinued bowel preparation after an adverse event. No electrolyte disorders or renal impairment was reported, even if not systematically sought. The acceptability of the NaP tablets was high, particularly among patients who previously had undergone other methods of bowel preparation.Despite being defined according to strict criteria, adequate use of NaP tablets was observed in a high percentage of patients. The quality of colon cleansing and the safety and acceptability of NaP tablets were satisfactory and consistent with data from randomized clinical studies.

Project description:BackgroundEfficient bowel cleansing is essential for a successful colonoscopy, but the ideal cleansing agent, volume, and pharmaceutical dosage form have yet to be determined. Small-volume cleansers enhance patient compliance.AimTo compare the bowel cleansing efficacy of 32-tablet sodium phosphate (Quiklean®) with 2-L polyethylene glycol (PEG)/bisacodyl (Klean-Prep/ Dulcolax®) under identical dietary recommendations.MethodsThis multicenter, randomized, parallel-group, noninferiority clinical trial enrolled 472 outpatients, randomized 456 subjects, and scheduled 442 subjects to undergo colonoscopy (Quiklean® = 222 and Klean-Prep/Dulcolax® = 220). After bowel preparation, a colonoscopist performed the colonoscopy with video recorded for rating. The primary efficacy endpoint was the bowel cleansing quality using the Aronchick Scale. The secondary endpoints were the bowel cleansing efficacy of three colon segments, tolerability and acceptability, safety using the Ottawa bowel preparation scale, questionnaires by subjects, and monitoring of adverse events.ResultsSuccess rates (Excellent + Good) of the bowel cleansing quality by Aronchick Scale were 98.6% (n = 205) and 97.6% (n = 204) in the Quiklean® and Klean-Prep/Dulcolax® groups, respectively. Quiklean® demonstrated noninferiority over Klean-Prep/Dulcolax® in colon cleansing efficacy. Quicken showed better tolerability and acceptability in the overall experience (was rated as excellent; 24.0% vs 17.2%; P = 0.0016) and the taste of the study preparation (was rated as excellent, 23.1% vs 13.4%; P < 0.0001) than Klean-Prep/Dulcolax®. Safety profiles did not differ between the two groups. Our data indicate that Quiklean® is an adequate, well-tolerated bowel cleansing preparation compared with the standard comparator Klean-Prep/Dulcolax®.ConclusionQuiklean® is sodium phosphate tablets available on Taiwan's market for bowel preparation; it potentially offers patients an alternative to standard large-volume bowel preparation regimens and may, therefore, increase positive attitudes toward colonoscopies and participation rates.
