Method and system for preventing sore throat in humans
First Claim
1. A buccal bioadhesive strip for treating sore throat in a human being, comprising:
- a solid strip having a first and second side, said first side having a surface comprising a pattern defined by a plurality of spaced apart features each having at least one microscale dimension and having at least one neighboring feature having a substantially different geometry, wherein an average spacing between adjacent ones of said features is between 0.5 and 5 microns in at least a portion of said surface, the first side having a bioadhesive that is adapted to bind to a mucosal membrane for at least 1 hour while inside a person'"'"'s mouth, wherein said strip is sized to extend over a majority of the soft palate, and wherein said strip includes xylitol and at least one encapsulated feature containing one of an analgesic and a lactic acid bacteria that coaggregates with S. pyogenes.

Abstract
A method and system to prevent sore throat infections in humans includes the administration of an active ingredient to a site on the mucus membranes of the throat of a human that inhibits adherence and promotes desorption of S. pyogenes to soft tissue surfaces, such as the pharyngeal and oral mucosa of a human. A mucoadhesive strip having a surface topography that resists bioadhesion of undesired bacteria that are typically present in a human'"'"'s mouth is preferably employed and that has one or more encapsulated agents selected from the group consisting of an antibiotic; lactic acid bacteria; S. pyogenes modified by a CRISPR-Cas system to reduce one or more virulence factors; and a breath mint solution.
