Desmopressin 120 mcg, 180 mcg, 240 mcg: The right treatment for the right patient.

BACKGROUND

The first-line drug therapy for patients with nocturnal enuresis (NE) associated with nocturnal polyuria and normal bladder function is desmopressin (dDAVP).

OBJECTIVE

To evaluate if increasing dose of oral desmopressin lyophilisate (MELT) can improve response rates to dDAVP and is useful in enuretic children.

MATERIALS AND

METHODS

We enrolled a total of 260 children all diagnosed with NE. Enuretic children were treated with increasing MELT at a dose of 120, 180 and 240 mcg a day.

RESULTS

We included in our study a total of 237 children, 164 males (69.2%) and 73 females (30.8%) aged between 5 and 18 years (mean age 10.32 ± 2.52 years). Of the 237 patients enrolled in the study and treated with MELT 120 mcg, a full response was achieved in 135 (56.9%). A partial response was achieved in 21 (8.9%) patients, therefore the dose was increased up to 180 mcg, with further improving symptoms (14.3%) or full response (9.5%), and up to 240 mcg, without usefulness.

CONCLUSIONS

MELT at the dose of 120 mcg resulted efficacy and safety; the increased dose up to 180 mcg resulted poorly efficacy; finally, the further increase up to 240 mcg did not improve the symptoms with the increased risk of side effects.
