EFFECTIVENESS OF SENNA IN TREATING CHRONIC CONSTIPATION IN GERIATRIC PATIENTS PRESENTING TO THE EMERGENCY DEPARTMENT: A RANDOMIZED, DOUBLE-BLIND, MULTICENTER STUDY

Introduction: Chronic constipation is prevalent in the geriatric population. Undiagnosed and untreated constipation can lead to complications and decreased health-related quality of life. The aim of this study was to compare the therapeutic effectiveness of senna alone with a combination of bisacodyl and senna in patients diagnosed with chronic constipation. Materials and Method: This prospective, multicenter, double-blind, randomized controlled trial included patients aged 65 years and older who presented to the emergency department with chronic constipation, diagnosed according to the Rome IV criteria, between July and October 2023. Patients were randomly assigned to either the senna group (20 mg sennoside B) or the senna + bisacodyl group (3 mg sennoside B + 5 mg bisacodyl). Participants took the drugs twice daily for 28 days. The Constipation Scoring System and Patient Assessment of Constipation Quality of Life scores were calculated before and after treatment for each patient. Results: The study included 105 patients, with 54 in the senna group and 51 in the senna + bisacodyl group. There was a statistically higher need for dose reduction because of drug side effects in the senna + bisacodyl group compared with the senna group (p=0.026). Following treatment, the senna group had a higher score on the Constipation Scoring System and Patient Assessment of Constipation Quality of Life compared with the senna + bisacodyl group, and the difference was statistically significant (p<0.001, p=0.012). Conclusion: In geriatric patients, short-term treatment of chronic constipation with senna is more effective than senna+bisacodyl regarding constipation severity and quality of life.
