| Abstract: | In 11 patients with vasopressin-sensitive diabetes insipidus the effectiveness of the vasopressin analogue 1-desamino-8-D-arginine vasopressin (DDAVP) for controlling diabetes insipidus has been compared with that of lysine vasopressin. DDAVP in equivalent intravenous dosage has been found to be at least as potent and to have a more prolonged action, lasting 13-22 hours instead of 1-2 hours. Twice-daily intranasal DDAVP effected satisfactory control in all these patients, without side effects, and all the patients preferred this to their previous treatment. Single daily intramuscular injections of DDAVP were found to offer excellent control for any subject unable to manage intranasal administration. |
