| Summary: | Objective: An interim analysis of postmarketing surveillance reported the safety and efficacy of elobixibat, a laxative medication that inhibits the ileal bile acid transporter, at 4 weeks in approximately 1000 patients with chronic constipation in Japan. However, its long-term safety and efficacy in elderly patients remain unclear. This study aimed to conclude and report the final analysis of postmarketing surveillance, including 52-week safety and efficacy profiles in a clinical practice setting, using approximately 3000 patients. Methods: The overall survey period spanned from June 2018 to May 2022. Observation periods were set at 4 weeks (4-week treatment period) and 52 weeks (52-week treatment period). Adverse drug reactions and efficacy outcomes, including defecation frequency, Bristol Stool Form Scale scores, and patient satisfaction, were analyzed. Results: The 4-week safety analysis set included 3638 patients with a mean age of 70.8 years, and 73.7% were aged ⩾65 years. Most patients (62.5%) were treated with elobixibat alone, while the rest received concomitant laxatives. In total, 231 patients (6.35%) experienced adverse drug reactions, with gastrointestinal disorders (6.02%) such as diarrhea (3.35%) and abdominal pain (2.06%), being the most common adverse drug reaction. The adverse drug reaction incidence in elderly patients aged ⩾65, ⩾75, and ⩾85 years was 5.49%, 4.85%, and 2.80%, respectively. In the 52-week treatment period, adverse drug reaction incidence was 5.40% (71/1315 patients), similar to that in the 4-week treatment period. Regarding efficacy, defecation frequency and Bristol Stool Form Scale scores significantly improved from week 2 onward, regardless of the age group and administration timing (before breakfast, lunch, or dinner). Most patients reported satisfaction from week 2 onward (6.0%, 66.9%, 78.6%, and 90.4% at baseline, weeks 2, 4, and 52, respectively). Conclusion: This study confirmed the long-term safety and efficacy of elobixibat in patients with chronic constipation, including many elderly ones, in routine clinical practice. |
