The prokinetic agent cisapride is effective for the treatment of gastroesophageal reflux disease (GERD) in infants and children, but is no longer used for this purpose because of safety concerns. Therefore, other pharmacological agents need to be investigated for efficacy in GERD treatment. In this study, we examined the effectiveness and safety of mosapride for the treatment of neurologically impaired children and adolescents with GERD.
Mosapride (0.3 mg/kg/day) was administered to 11 neurologically impaired patients with GERD (five male; median age, 12.3 years). Esophageal acid exposure was measured using esophageal pH monitoring before and at >5 days after the start of mosapride treatment. The pressure and length of the lower esophageal sphincter were compared before and after mosapride treatment.
In the 11 patients, median reflux index (percentage of the total monitoring period during which recorded pH was <4.0) was 17.5% (range, 4.4-59%) before and 8.2% (range, 2.8-20.7%) after mosapride treatment (P = 0.02). Median esophageal clearance was 1.0 min/reflux (range, 0.5-2.1 min/reflux) before and 0.7 min/reflux (range, 0.4-1.2 min/reflux) after treatment with mosapride (P = 0.02). The median number of reflux episodes before (219) and after (122) drug treatment did not differ significantly.
The decreased reflux index in neurologically impaired patients with GERD is due to mosapride, therefore mosapride may be a candidate for GERD treatment.
促动力药西沙必利对婴幼儿和儿童胃食管反流病(GERD)的治疗有效,但由于安全问题已不再用于该目的。因此,需要研究其他药物治疗GERD的疗效。在本研究中,我们检测了莫沙必利治疗神经功能受损的GERD患儿及青少年的有效性和安全性。
对11例神经功能受损的GERD患者(5例男性;中位年龄12.3岁)给予莫沙必利(0.3mg/kg/天)治疗。在莫沙必利治疗开始前及治疗5天以上时,采用食管pH监测法测量食管酸暴露情况。比较莫沙必利治疗前后食管下括约肌的压力和长度。
11例患者中,莫沙必利治疗前反流指数(记录pH<4.0的总监测期百分比)中位数为17.5%(范围4.4%-59%),治疗后为8.2%(范围2.8%-20.7%)(P=0.02)。莫沙必利治疗前食管清除中位数为1.0分钟/反流(范围0.5-2.1分钟/反流),治疗后为0.7分钟/反流(范围0.4-1.2分钟/反流)(P=0.02)。药物治疗前后反流发作中位数(分别为219次和122次)无显著差异。
神经功能受损的GERD患者反流指数降低是由于莫沙必利所致,因此莫沙必利可能是GERD治疗的候选药物。
