Results of treatment of gastroesophageal reflux with bethanechol.

Thirty-seven infants and children with gastroesophageal reflux were studied with prolonged esophageal pH monitoring before and during treatment with bethanechol. Total reflux scores improved by 69% (P = 6.47 X 10(-7) during bethanechol therapy. This improvement resulted primarily from decreases in the frequency and the duration of reflux episodes occurring more than two hours after feeding. Our findings indicate that infants and children with gastroesophageal reflux may safely be treated with bethanechol; thus the need for surgery is avoided.
