Abstract
Constipation is a complicated condition. Chronic constipation is diagnosed when constipation occurs for more than 3 months. Chronic constipation is classified using patient symptoms and the pathophysiology. New therapeutic agents to treat chronic constipation have recently been approved in Japan. However, treatments for constipation that is refractory to traditional laxatives have been approved, an algorithm for the treatment of chronic constipation has not yet been developed. The accumulation of knowledge and data is necessary to develop a new algorithm.

Abstract
BACKGROUND Potential habituation could be a safety concern associated with the long-term use of bisacodyl in patients with constipation. OBJECTIVE In this study, we evaluated whether patients with constipation who require long-term treatment with bisacodyl will remain on a stable dose when treated for ≥ 28 days. METHODS In this retrospective, population-based, observational cohort study, electronic medical record data of adult patients with constipation between January 1, 2011, and December 31, 2019, were collected from The Health Improvement Network French database. Total bisacodyl exposure during the long-term (≥ 28 days) and follow-up (12 months) periods was evaluated. The primary endpoint was the dose change status of bisacodyl during the follow-up period from the initial dose in the long-term cohort. RESULTS Out of 5725 bisacodyl users in the database, 218 patients qualified to be part of the long-term cohort. A total of 166 (76.1%), 37 (17%), and 15 (6.9%) patients were initiated on bisacodyl at 5, 7.5, and 10 mg, respectively. During the follow-up, most (94%) of the patients remained on the same dose as initially prescribed for the first year. In contrast, only seven (3.2%) patients had their dose increased (from the initial prescribed dose of 5 mg), and the remaining six (2.8%) patients decreased their dose (four patients from the 7.5 mg group and two from the 10 mg group). CONCLUSION Bisacodyl can be prescribed at a stable dose for > 28 days as most patients remained on their initial prescribed dose during the follow-up period. No signs of habituation were observed in this real-world study.

Efficacy and safety of lubiprostone for the treatment of functional constipation in Chinese adult patients: A multicenter, randomized, double-blind, placebo-controlled trial. J Dig Dis 2021; 22:622-629. [PMID: 34633753 DOI: 10.1111/1751-2980.13058] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/19/2021] [Revised: 09/12/2021] [Accepted: 10/03/2021] [Indexed: 12/11/2022]
Abstract
OBJECTIVES Functional constipation is a gastrointestinal disorder prevalent around the world. Lubiprostone is the first locally acting type-2 chloride channel activator to be used for treating constipation. This study aimed to evaluate the efficacy and safety of lubiprostone in Chinese adults with functional constipation. METHODS This was a multicenter, randomized, double-blind, placebo-controlled study. Patients with functional constipation were randomized to receive either lubiprostone (24 mcg twice daily) or placebo for 4 weeks. The primary end-point was the frequency of spontaneous bowel movements (SBMs) during the first week of treatment. The secondary end-points included the median time of the first SBM, SBM frequency at weeks 2, 3 and 4, weekly response rate of SBMs, the stool consistency score and average number of complete spontaneous bowel movements (CSBMs) per week. RESULTS In total, 259 patients were randomized, with 130 in the lubiprostone group and 129 in the placebo group. SBM frequency was higher in the lubiprostone group (4.88 ± 4.09/wk) than that in the placebo group (3.22 ± 2.01/wk) at week 1 (P < 0.0001). SBM frequency was also higher in the lubiprostone group at weeks 2, 3 and 4. The average number of CSBMs and the stool consistency score in the lubiprostone group were significantly higher than that in the placebo group at each week. No drug-related serious adverse events (AEs) occurred. The most commonly reported AE was nausea. CONCLUSION Lubiprostone was superior to placebo in treating Chinese patients with functional constipation, together with good safety profile.
