title: Gastric myoelectric activity in older adults treated with cisapride for gastro-oesophageal reflux disease.
abstract: BACKGROUND
  The incidence of both gastro-oesophageal reflux disease (GERD) and upper gastrointestinal motility disorders appears to increase with age. However, there is a dearth of data concerning the utility of a prokinetic agent such as cisapride in the treatment of older adults with symptomatic GERD.
  
  
  OBJECTIVE
  To investigate the incidence of electrogastrographic abnormalities in older adults with and without GERD symptoms, as well as the effect of cisapride therapy on symptoms of GERD and electrogastrographic responses.
  
  
  METHODS
  We report on 18 older adults with symptomatic GERD and 10 older adult controls (mean ages 71 and 75 years, respectively). Subjects underwent electrogastrographic evaluation pre- and postprandially under baseline conditions and after 1 month of treatment with 10 mg q.d.s. of cisapride.
  
  
  RESULTS
  Heartburn frequency and postprandial fullness were both significantly (P < 0. 05) reduced after cisapride treatment. Acid contact time was not significantly changed. The percentage of 2-4 cpm activity in the electrogastrographic analysis was significantly (P < 0.05) increased with cisapride treatment, and the instability coefficient was significantly (P < 0.05) diminished with cisapride treatment.
  
  
  CONCLUSIONS
  Enhanced gastric functioning and reduction in heartburn suggest that cisapride is efficacious in the treatment of older adults with symptomatic GERD, and that gastric dysrhythmias and postprandial fullness are resolved with cisapride treatment.
