Copeptin measurements upon intravenous arginine stimulation discriminate patients with diabetes insipidus versus patients with primary polydipsia with a high diagnostic accuracy. An oral test would be easier to perform, causes less risks and discomfort for the patients and would require less resources in clinical practice. This study investigates stimulation of the posterior pituitary gland by oral Macimorelin (a ghrelin receptor Agonist) to be a novel diagnostic test in the polyuria-polydipsia syndrome.
