Medical therapy remains the most popular treatment for gastroesophageal reflux disease (GERD). Whilst interest in drug development for GERD has declined over the last few years primarily due to the conversion of most proton pump inhibitor (PPI)'s to generic and over the counter compounds, there are still numerous areas of unmet needs in GERD. Drug development has been focused on potent histamine type 2 receptor antagonist's, extended release PPI's, PPI combination, potassium-competitive acid blockers, transient lower esophageal sphincter relaxation reducers, prokinetics, mucosal protectants and esophageal pain modulators. It is likely that the aforementioned compounds will be niched for specific areas of unmet need in GERD, rather than compete with the presently available anti-reflux therapies.
药物治疗仍然是胃食管反流病(GERD)最常用的治疗方法。尽管过去几年对GERD药物研发的兴趣有所下降,主要原因是大多数质子泵抑制剂(PPI)转为非专利药和非处方药,但GERD仍存在许多未满足的需求领域。药物研发一直集中在强效组胺2型受体拮抗剂、缓释PPI、PPI联合用药、钾离子竞争性酸阻滞剂、短暂性下食管括约肌松弛抑制剂、促动力药、粘膜保护剂和食管疼痛调节剂。上述化合物可能会针对GERD未满足需求的特定领域,而不是与现有的抗反流疗法竞争。
