To review the literature on the treatment of gastroesophageal reflux disease (GERD) with emphasis on pharmacological aspects. To identify particularities of pharmacological treatment of esophageal and extraesophageal manifestations of the disease.
Electronic search of the PubMed/MEDLINE and Cochrane Collaboration databases. Controlled and randomized studies published since 2000 and reviews representing consensus positions and directives published within the last 10 years were identified.
The drugs currently available for the treatment of GERD do not act in the primary mechanism of the disease, i.e. transitory relaxation of the lower esophageal sphincter. Pharmacological treatment of GERD with symptoms or with esophageal injury is based on the suppression of acid secretion, particularly with proton pump inhibitors. When the hyperreactivity of the lower airways coexists with esophageal GERD symptoms, suppression of acid secretions should be of benefit in managing the respiratory disease in the presence of a causal relationship; however, this is not usual. When esophageal symptoms are not present, esophageal 24-hour pH study should be carried out prior to starting pharmacological treatment for GERD. Improvement of respiratory symptoms may be delayed with relation to esophageal symptoms. It is common for GERD to recur and pharmacological treatment should be repeated or continued indefinitely, depending on clinical presentation of the disease.
The strategies that have been proposed for the pharmacological treatment of GERD in children are primarily based on studies of case series or on studies with adults. There have been very few controlled and randomized studies in children. Undertaking a greater number of these studies might reinforce existing aspects or establish new aspects of management.
回顾关于胃食管反流病(GERD)治疗的文献,重点关注药理学方面。确定该疾病食管和食管外表现的药物治疗特点。
对PubMed/MEDLINE和Cochrane协作数据库进行电子检索。检索2000年以来发表的对照和随机研究,以及代表过去10年内共识立场和指南的综述。
目前可用于治疗GERD的药物并非作用于该疾病的主要机制,即食管下括约肌的短暂松弛。对有症状或有食管损伤的GERD进行药物治疗基于抑制胃酸分泌,尤其是使用质子泵抑制剂。当下呼吸道高反应性与食管GERD症状并存时,若存在因果关系,抑制胃酸分泌对控制呼吸系统疾病应有益处;然而,这种情况并不常见。当不存在食管症状时,在开始GERD药物治疗前应进行食管24小时pH监测。呼吸系统症状的改善可能相对于食管症状会延迟。GERD复发很常见,药物治疗应根据疾病的临床表现重复进行或无限期持续。
已提出的儿童GERD药物治疗策略主要基于病例系列研究或成人研究。儿童中对照和随机研究非常少。开展更多此类研究可能会强化现有治疗方面或确立新的治疗方面。
