A reflux suppressant
is any one of a number of drugs
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 coincidentally reduced by the Motility stimulants and antidopaminergics.
