H2 Receptor Antagonists
H2 Receptor Antagonists – such as Gavilast - are called histamine receptor blockers and work at the source of acid production, blocking a process by which the stomach makes acid. Known as acid suppressing medicines their effect can last for up to 12 hours – i.e. all day or all night, although they may take a little time to kick in.
The active ingredients can include cimetidine, famotidine, nizatadine or ranitidine.
If you keep getting heartburn or indigestion, your symptoms are severe, or they do not respond to other medicines, it is worth consulting your GP.
