[Diltiazem in esophageal motility disorders]

The effects of the calcium blocking agent diltiazem upon esophageal motility was studied with electromanometric technique in 23 patients. In 10 achalasic patients lower esophageal sphincter pressure was reduced in 40.1%, in the remaining 13 in only 19.15%. Other parameters showed only minor changes such as reduction in the pressure of contractile waves in the body of the esophagus.
