Method and composition for treating gastro-esophageal disorders

摘要

An orally administered composition that includes least one alkaline agent with a pH of at least 9.0 to 12.0, mixed in an aqueous vehicle with relatively high surface tension, high viscosity and lateral adhesion properties. When mixed, a low water soluble emulsion is formed that evenly coats and partially adheres to the lower section of the esophagus and the LES and forms a relatively long acting, protective barrier and partially neutralizes gastric acid. In one embodiment, the alkaline agent is potassium hydroxide and the aqueous vehicle is made of hydroxypropyl methyl cellulose, polyethylene glycol or ethylene glycol and additional thickener agents capable of withstanding high pH environments, such as xanthan gum, croscarmellose sodium, and microcrystalline cellulose. Additional organoleptic agents, such as gum Arabic and polyethylene glycol, flavorings, such as sodium chloride, acesulfame potassium, sodium saccharine, and mint, and stabilizers such as colloidal silica made be added.

1. A method of reducing or treating damage to the esophagus and the lower esophageal sphincter caused by physical trauma or gastric acid, comprising the administrating to a patient in need thereof an oral composition in the form of an emulsion consisting of:
an alkali metal hydroxide 0.25% to 6.0% by weight, a thickening agent, and an organoleptic agent mixed in water that produces a pH between 9.0 to 12.0 and a specific gravity value from 1.05 to 1.15 gm/ml, a viscosity value between 6000 to 29,000 cP, and a lateral adhesion value between 10−2 to 10−6 Newtons, said organoleptic agent selected from the group consisting of: hydroxypropyl methyl cellulose, polyethylene glycol or ethylene glycol; an optional alkaline agent; an optional stabilizing suspending agent; and, an optional flavoring agent.
