The evolution of the muco-adhesive patch has found commercial viability in treating canker sores as well because the patch can also act as a bandage for the sores for eight to twelve hours while releasing active remedial ingredients.Dry mouth affects upwards of 17% of the population, increasing in older adults (65 years and older) to about 30%. In fact, 34% of people taking three or more medications suffer from dry mouth, which is also a chronic symptom of numerous medical conditions, such as diabetes and Sjogren's Syndrome.

Study Findings The objective of this study was to evaluate a muco-adhesive lipid-based bioerodable patch as a novel device to decrease signs and symptoms associated with dry mouth, compared to the leading oral rinse. The study consisted of 20 patients who suffered from dry mouth for more than three months as a result of medical conditions, who were divided into two treatment groups - oral rinse and muco-adhesive patch.

The questionnaires completed prior to treatment showed no statistically significant differences between the groupsFollowing treatment, 40% of muco-adhesive patch users reported significantly more moisture and a reduction in the sensation of dry mouth vs. 20% of the leading mouthwash usersThere was a 1.5-fold increase in unstimulated whole saliva flow (UWSF) after 30 minutes in the group using the muco-adhesive patchIn addition, 70% of patients treated with the muco-adhesive patch reported they would continue using the product in the future, compared to only 30% who would continue using the leading mouthwash
