Eligibility
Inclusion criteria
Inclusion criteria: • Male or female, over 18 years of age, and capable of providing their written informed consent. • An unstimulated whole mouth salivary flow < 0.20 ml/min [8]. • Demonstrated moderate to severe level of dry mouth at screening, as indicated by an XI-score of 25 or higher • Diagnosis of Sjögren's syndrome. • Access to internet.
Exclusion criteria
Exclusion criteria: • Patients currently using a potassium-sparing diuretic antihypertensive drug that contains amiloride; spironolactone (e.g.,Aldactone, Novo-Spiroton, Spiractin, Spirtone, Verospiron or Berlactone); triamterene (e.g., Dyrenium); or plerenone (e.g., Inspra).

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary objective of this study is to evaluate the effect of an artificial saliva substitute on the sensation of a dry mouth. This will be measured according to a VAS questionnaire for subjective assessment of salivary dysfunction. In addition, the Xerostomia Inventory will be used to quantify the severity of oral dryness. | — |
Secondary
| Measure | Time frame |
|---|---|
| A secondary objective of this study is to evaluate the overall appreciation of the saliva substitute. This objective will be assessed by a product appraisal questionnaire. Another secondary objective is to evaluate effects of the artificial saliva on the saliva secretion rate. | — |
