COMPOSITIONS FOR PREVENTION AND TREATMENT OF SYMPTOMS SIMILAR TO THE SYMPTOMS OF COLD AND INFLUENZA CONTAINING SELECTED MUCHABLE POLYMERS AND METHODS OF TREATMENT

摘要

The present invention is directed to respiratory tract compositions that are highly effective in the prevention and treatment of cold and influenza-like symptoms due to respiratory tract viral infections. These compositions preferably comprise a metal compound such as zinc acetate, an organic acid, and a select mucoadhesive polymer, wherein the select mucoadhesive polymer provides for adherence of the compositions to mucosal tissues and fluids to result in improved prevention and treatment of cold and influenza-like symptoms.
