Management of cranial diabetes insipidus with oral desmopressin (DDAVP).

The effect of oral administration of desmopressin (DDAVP) solution was investigated in six patients with cranial diabetes insipidus of varying aetiology. All patients experienced a prompt and prolonged antidiuresis. Nine patients have been managed with oral DDAVP tablets for up to 5 months and all preferred this route of administration to intranasal application using a rhinyle. Oral DDAVP gives excellent and convenient control in cranial diabetes insipidus.
