Prior dosage of intranasal desmopressin significantly correlated with the required ODT dose. Although there are many factors responsible for the secretion of vasopressin like nausea, acute hypoglycemia, glucocorticoid deficiency, smoking, the most important stimulus is increased plasma osmolality [ 12 ]. Inconsistent data were reported on the diagnostic superiority of direct plasma arginine vasopressin determination over the indirect water deprivation test.

Overall, sensitivity to the antidiuretic effect of desmopressin with females was higher than males. The ratio of ODT to intranasal desmopressin dose was Temporal delays and individual variation in antidiuretic response to desmopressin.
PP differs from the other causes of DI in that it does not diabettes from a deficient AVP secretion or activity, but rather results from an excessive fluid intake practiced over an extended period of time prg The patient is allowed fluids overnight. View at Google Scholar P.
