This paper presents a literature review of two commonly used osmotic laxatives, lactulose and polyethylene glycol (PEG). With increasing numbers of nurses in the community being non-medical prescribers, informed decisions on choice of laxatives is required. Nurses who do not prescribe will often have a view for the benefit of their patients. Following a literature search, eight papers were selected for review. The review leads to the conclusion that, while both preparations are useful, PEG is more effective in many instances and should be the laxative of choice unless there are contraindications arising from the assessment of the patient. Non-pharmacological approaches to the management of constipation should be addressed before considering laxative use.
本文对两种常用的渗透性泻药——乳果糖和聚乙二醇（PEG）进行了文献综述。随着社区中越来越多的护士成为非医学开处方者，在选择泻药时需要做出明智的决定。不开处方的护士通常也会从患者的利益出发提出看法。在进行文献检索后，挑选了八篇论文进行综述。综述得出的结论是，虽然两种制剂都有用，但在许多情况下PEG更有效，并且除非对患者的评估出现禁忌证，否则PEG应作为首选泻药。在考虑使用泻药之前，应先探讨便秘管理的非药物方法。
