About

Dry mouth is in most cases due to iatrogenic causes, particularly drugs. The existing products such as saliva substitutes are often disappointing (bad taste, poor efficiency).

Our hypothesis has considered the "empirical" observations made by some patients with xerostomia who consumed milk products to relieve the dry mouth syndrome from which they suffered. With this clinical observation, a closer collaboration has been undertaken with research laboratories specialising in food and especially milk. Through its composition, the dairy product in itself provides relief for the patient, due both to its physical and biochemical properties, which could explain these observed improvements, and elements related to the phenomena of consumption of food as an alternative to medication. In the latter, hedonism takes on a role which has not been previously assessed. Initial work undertaken with the department of applied research at the National Dairy Industry School (ENIL) led to the prototyping of a new natural milk, which is the subject of this application for development, to qualify and adapt a product with a "health benefit" in patients suffering from xerostomia.

To further develop this project we will initiate a sequential clinical trial by groups of five ambulatory patients with xerostomia (patients taking antidepressants followed in psychiatry appointments). The clinical tests will be organised by the CIC with the psychiatric wards of the University Hospital of Besançon. Each group of 5 patients will test a similar product for 14 days. The information collected after a series of tests with a group of patients will be translated by changing the ENIL specifications to produce a new mini-series of products. This repetition will be carried out up to 3 times if necessary to help achieve a satisfactory product in terms of taste, texture and lubrication properties, which will then be tested in a randomized controlled cross-over study of the efficiency and acceptability of the new "LactoXeros" product versus a reference product (Aequasyal ®, Oxidized Glycerol Triester) on a group of 32 patients at the University hospital of Dijon.

A natural way to combat xerostomia at the interface of patient diet, such as we propose, could help improve quality of life for patients, minimize harmful effects (infection, decay) and promote adherence of patients to treatments which are responsible for xerostomia.

Lactoxeros milk product
Experimental group
Description:
Patient will take the milk product orally for 14 days as many times as needed per day(but not more than 6 times daily).
Treatment:
Other: LactoXeros
Aequasyal
Other group
Description:
Patients will take the oral spray for 14 days. The Aequasyal ® Oral Spray is a solution of oxidized glycerol triesters. The oral spray is applied by spraying on the inside of each cheek, 3-4 times per day. After each administration, users are instructed to gently spread the product around the mouth with the tongue. The Aequasyal ® Oral Spray is a Class I medical device, and is CE-marked.
Treatment:
Device: Aequasyal
