Physostigmine and metoclopramide in oesophageal peristaltic spread in man.
Simultaneous recordings of electrical and mechanical activities at different levels of the oesophagus were performed in normal men before and after physostigmine and metoclopramide injections. Various parameters of the basal oesophageal peristalsis were significantly modified following drug treatment. In particular, physostigmine injections induced a shortening of electromechanical coupling time and a reduction of the propagation velocities of the electrical and mechanical oesophageal events. Metoclopramide shortened the electromechanical coupling time but increased the electrical and mechanical propagation velocities along the oesophagus.
