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.

Oral Drug Delivery Systems: Continuous-Release Systems

Continuous-release drug delivery systems offer a strategic approach to maintaining therapeutic drug levels over extended periods following oral administration. By modulating the release rate of active pharmaceutical ingredients, these systems minimize fluctuations in plasma concentrations, which enhances clinical efficacy and reduces the need for frequent dosing. Such characteristics make them particularly advantageous in managing chronic diseases where patient adherence and stable drug...

Diabetes Insipidus I: Introduction

Definition Diabetes insipidus is a disorder marked by the production of large amounts of dilute urine because of impaired vasopressin production, release, or kidney response. The lack of effective vasopressin action limits water reabsorption in the renal collecting ducts, which leads to excessive urinary water loss and intense thirst.Clinical PresentationIndividuals with diabetes insipidus report persistent thirst and very high urine output. In severe cases, fluid intake can reach up to 20...
The Micturition Reflex01:26

The Micturition Reflex

Urination, or micturition involves the coordination of the bladder's detrusor muscle and two sphincters to ensure controlled bladder emptying.
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...

Diabetes Insipidus II: Pathophysiology

Normally, water balance is maintained through three interconnected mechanisms: the hypothalamic thirst center, the synthesis and release of antidiuretic hormone (ADH, or vasopressin), and the kidneys' responsiveness to this hormone. ADH is synthesized in the hypothalamus, released from the posterior pituitary, and acts on the distal nephron, allowing water reabsorption and concentrated urine production.Diabetes Insipidus and Its TypesIn diabetes insipidus (DI), this regulatory system is...

Sedatives and Hypnotics Drugs: Miscellaneous Agents

Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
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...

Drug Accumulation During Multiple Dosing: Intermittent IV Infusions

Intermittent intravenous (IV) infusion is a method of drug administration where medications are delivered over short infusion periods followed by intervals of no drug delivery. This approach helps to prevent sustained high drug concentrations in the bloodstream, reducing the risk of adverse effects associated with prolonged exposure. Unlike continuous infusion, steady-state concentrations may not be achieved during a single dosing cycle but can be reached through repeated...
