Literature regarding patient preference and acceptance in polyethylene glycol preparations is scarce. Therefore, this research aimed to identify preference between the three polyethylene glycol 3350, namely Molaxole®, Movicol®, and Laxtra Orange®. Furthermore, taste is one of the most important factors leading to patients’ adherence, particularly when the treatment lasts for a long time.Methods: In this randomized, cross-over double-blind study, 100 volunteers were recruited by advertisement. The volunteers were invited to taste the preparations and grade the taste using a five-point hedonic scale (extremely poor taste [1] to extremely good taste [5]). The volunteers were then asked to choose the most palatable preparation.Results: One hundred volunteers with a mean age of 35 years (range 20–61) were randomized (76 females). Molaxole®, Movicol®, and Laxtra Orange® had a mean hedonic score of 2.76 (SD: 0.82), 2.81 (SD: 0.76) and 3.12 (SD: 0.82) respectively. The hedonic taste score for Laxtra Orange® was significantly better than Molaxole® (P = 0.001) and Movicol® (P = 0.001). No difference was found between Molaxole® and Movicol® (P = 0.61). Molaxole® was the most preferred preparation for 19 volunteers (19%), Movicol® for 24 volunteers (25%) and Laxtra Orange® for 55 volunteers (56%). Two volunteers had no preference. The order in which volunteers tested the preparations had no influence on the taste results. No significant differences in age or gender were observed.Conclusion: Laxtra Orange® was most palatable preparation. This may have implications for adherence in patients with chronic constipation.Keywords: constipation, polyethylene glycol, laxative, macrogol, molaxole, movicol, laxtra, medication adherenc
