Proton pump inhibitors (PPIs) are commonly prescribed for treatment of acid-related gastrointestinal disorders. PPI use is approved for a duration of 2 to 12 weeks, depending on complication and severity. Many users lack an appropriate indication for continued therapy past the recommended duration. Long-term PPI use is associated with several adverse drug events, including acute interstitial nephritis, fractures, and Clostridium difficile-associated diarrhea (CDAD). Cautious prescribing and regular monitoring is essential, especially for older adults, as they may be at higher risk for these adverse effects. Deprescribing, defined as lowering dosage, switching to as-needed use, or complete discontinuation, should be considered for many PPI users. Patient education is critical. Alternative therapy considerations include histamine-2-receptor antagonists, as they are found to be associated with reduced CDAD and fracture events. Additional strategies include tapering off PPIs and modifying lifestyle to reduce the potential rebound hypersecretion that may occur as a result of discontinuation. The most significant lifestyle modification is weight loss. Additional lifestyle interventions include upright head of bed elevation, avoiding meals close to bedtime, and avoiding high-fat meals within two to three hours of reclining.
质子泵抑制剂(PPIs)常用于治疗与酸相关的胃肠道疾病。根据并发症和严重程度,PPI的使用批准疗程为2至12周。许多使用者在超过推荐疗程后仍缺乏继续治疗的适当指征。长期使用PPI与多种不良药物事件相关,包括急性间质性肾炎、骨折和艰难梭菌相关性腹泻(CDAD)。谨慎开药和定期监测至关重要,尤其是对老年人而言,因为他们可能面临这些不良反应的更高风险。对于许多PPI使用者,应考虑减药,即降低剂量、改为按需使用或完全停药。患者教育至关重要。替代疗法可考虑使用组胺-2受体拮抗剂,因为它们与CDAD和骨折事件减少有关。其他策略包括逐渐停用PPI以及改变生活方式,以减少因停药可能出现的潜在胃酸分泌反跳性增高。最重要的生活方式改变是减肥。其他生活方式干预措施包括将床头抬高呈直立位、避免在接近就寝时间进食以及在躺下前两到三小时内避免食用高脂肪食物。
