Evaluating lubiprostone for effective bowel preparation before colonoscopy

Abstract

Abstract Background Colon preparation is a fundamental step for performing a successful colonoscopy. We aimed to evaluate the effectiveness of administering lubiprostone (LB) added to a single dose of oral polyethylene glycol (PEG) solution in achieving satisfactory colon cleanliness and decreasing the side effects. Results One-hundred percent of the control group patients reported that the experienced taste was worse than expected, while in the intervention group half of the patients (50%) said that the taste was natural and 48% experienced taste worse than expected (p<0.0001). Regarding Boston bowel preparation scale (BBPS), there was a significant difference in the overall Boston scale (p=0.02) with more efficacy in the intervention group as 66% of patients in the intervention group had good bowel preparation (5–7) and 24% excellent preparation (8–9). On the other hand, the overall Boston scale in the control group showed that 54% of patients were between 5 and 7, and only 16% of patients had overall Boston scale 8–9. In terms of the side effects of the preparation in both arms, the majority of cases in the intervention arm did not complain of any side effects (78%), while the majority of the complaints were vomiting in 16% of the intervention cases. Conclusion The current evidence suggested that adding LB to the colon preparation significantly improved the tolerability and efficacy.
