Does the use of nizatidine (Tazac) as a prokinetic agent improve gastric emptying in patients who have had an oesophagectomy for oesophageal cancer?

This study looks at whether a medication called nizatidine (brand name Tazac), which is normally used to treat stomach ulcers and acid reflux, can also help the stomach empty food more efficiently in people who have had surgery to remove the oesophagus (the tube connecting your throat to your stomach) because of cancer. After this surgery, many patients experience slow stomach emptying, which causes discomfort. Participants take the medication for one week and have a special stomach scan before and after to measure any changes.
