Any
drug used to combat
oesophageal reflux[?]. Commonly, following ingestion a 'raft' of alginic acid is created, floating on the stomach contents by carbon dioxide released by the drug. This forms a mechanical barrier to further reflux. Some preparations also contain
antacids to protect the
oesophagus.
Reflux can also be co-incidentally reduced by the prokinetic agent[?] and antidopaminergics[?].
