The Role of Docusate for Constipation in Older People.

Abstract

Objective: To provide brief information on the effectiveness of docusate use for constipation in older people. Data Sources: PubMed search using the following terms ("docusate and chronic constipation," "docusate, chronic constipation and geriatric," "docusate, chronic constipation and older adult," "docusate and randomized controlled trial" and included relevant information related to docusate and chronic constipation in the population described. Study Selection: Studies that fit the criteria for "chronic/general constipation," "geriatric/older adults," and/or "randomized controlled trials" were included. Four studies described docusate for chronic/general constipation and older people. Not included were other studies not related to chronic/general constipation and older people (eg, surgery-related). Data Extraction: Data extraction from each study included primary outcomes related to chronic constipation and efficacy of docusate. Data also included relevant reports from other relevant trials and discussions. Data Synthesis: Docusate when compared with placebo or psyllium or sennosides in these trials did not show any benefits for constipation. Psyllium and sennosides showed to be more effective compared with docusate. No differences found between docusate versus placebo. In summary, there is a lack of data to support the use of docusate for constipation and the data presented that docusate is not effective for use in constipation. Conclusion: Docusate is commonly used for constipation despite little evidence supporting its efficacy. There is not enough randomized controlled trial and data to support the use of docusate for constipation. Pharmacists along with health care providers should reassess and reconsider whether to use it and add extra layers to an already complex medication regimen in the older adult population.
