Insights
Structured withdrawal from desmopressin lyophilisate (MELT) did not reduce relapse rates for nocturnal enuresis compared to abrupt cessation. This finding suggests abrupt discontinuation is a viable option for managing bedwetting in children.
Area of Science:
- Pediatric Nephrology
- Sleep Medicine
- Pharmacology
Background:
- Monosymptomatic nocturnal enuresis is common in children.
- Desmopressin is a standard treatment for nocturnal enuresis.
- The optimal method for discontinuing desmopressin therapy is not well-established.
Purpose of the Study:
- To compare the efficacy of a structured withdrawal program versus abrupt cessation of desmopressin lyophilisate (MELT) in treating monosymptomatic nocturnal enuresis.
- To determine if a gradual reduction in MELT dosage reduces relapse rates after treatment cessation.
Main Methods:
- A randomized controlled trial involving 81 children aged 5.5–14 years treated with MELT (120 mcg/day).
- Responders were randomized to either abrupt withdrawal or a structured 30-day tapering program.
- Relapse was defined as >2 nights of bedwetting per month, assessed 1 month post-treatment.
Main Results:
- The relapse rate at 1 month post-treatment was 47.83% in the structured withdrawal group and 45.83% in the abrupt termination group.
- There was no statistically significant difference in relapse rates between the two withdrawal methods (p = 0.89).
Conclusions:
- A structured withdrawal program from desmopressin lyophilisate (MELT) does not offer significant advantages over abrupt termination in preventing relapse of monosymptomatic nocturnal enuresis.
- Abrupt cessation appears to be a similarly effective strategy for discontinuing MELT therapy in this pediatric population.
Objective:
To investigate whether a structured withdrawal program from a sublingual formulation of fast-melting oral desmopressin lyophilisate (MELT) is superior to a sudden withdrawal from this formulation in the treatment of monosymptomatic nocturnal enuresis.
Materials And Methods:
One hundred and three children presented to our pediatric nephrology outpatient clinic for bedwetting. Eighty-one children, aged between 5½ and 14 years (mean age 8.64 years), were treated with MELT at a dosage of 120 mcg a day. Responders were randomized to been withdrawn from therapy, after 3 months, abruptly or in a structured withdrawal program (60 mcg/day for 15 days and then 60 mcg every second evening for another 15 days). Main outcome parameter was relapse rate 1 month after the end of treatment. Relapse was defined as bedwetting occurring more than 2 nights per month after the 1-month treatment-free period.
Results:
Relapse rate at 1 month after the end of treatment was 47.83% in the group on a structured program versus 45.83% in the abrupt termination group (p = 0.89).
Conclusion:
Our study suggests that a structured withdrawal program from MELT therapy doesn't offer advantages compared to an abrupt termination in children with monosymptomatic nocturnal enuresis.

Diabetes Insipidus I: Introduction
The Micturition Reflex
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating urine...

Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
