First Claim
1. A pharmaceutical composition for the treatment of gastro-oesophageal reflux disease which comprises(1) a carrier vehicle which is capable of producing a floating barrier layer on contact with gastric acid or which is capable of forming a bioadhesive film which binds to the oesophageal region, and (2) at least one active ingredient selected from capsaicin ((E)-(N)-[(4-hydroxy-3-methoxyphenyl)-methyl]-8-methyl-6-nonenamide), zingerone (4-(4-hydroxy-3-methoxyphenyl)-2-butanone), curcumin (1,7-bis(4-hydroxy-3-methoxyphenyl)-1,6-heptadiene-3,5-dione), piperine (1-[5-1,3-benzodioxol-5-yl)-1-oxo-2,4-pentadienyl]-piperidine), resiniferatoxin (daphnetoxin 6,7-deepoxy-6,7-didehydro-5-deoxy-21-dephenyl-21-(phenylmethyl)-20-(4-hydroxy-3-methoxybenzene acetate), pharmaceutically acceptable derivatives and salts thereof.

Abstract
Formulations for the treatment of gastro-oesophageal reflux diseases include a carrier vehicle and an active gastro-protective agent. The carrier vehicle is either capable of forming a floating barrier layer on contact with gastric acid or of forming a bioadhesive film before any contact with gastric acid, so as to protect gastric mucosa from irritation by the gastric acid. A preferred active ingredient is capsaicin. The carrier vehicle preferably contains alginate or cross-linked polyacrylic acid.
