Insights

This study explored controlled-release (CR) melatonin doses for children with chronic sleep disorders. CR melatonin effectively improved sleep maintenance in children with neurodevelopmental difficulties, often requiring higher doses than adults.

Area of Science:

  • Pediatric Neurology
  • Sleep Medicine
  • Pharmacology

Background:

  • Chronic sleep-wake cycle disorders are prevalent in children with severe neurodevelopmental difficulties.
  • Limited research exists on effective melatonin dosing for this population.

Purpose of the Study:

  • To investigate the effective doses of controlled-release (CR) melatonin in children with chronic sleep-wake cycle disorders.
  • To compare the effectiveness of fast-release (FR) and CR melatonin formulations.

Main Methods:

  • A randomized double-blinded cross-over design was initially used for 16 children.
  • CR melatonin was further studied on a clinical basis for the remaining patients (total N=42).
  • Effectiveness was assessed using sleep charts, clinical follow-up, and parental feedback.

Main Results:

  • The average final CR melatonin dose was 5.7 mg (range: 2-12 mg).
  • Fast-release (FR) melatonin was more effective for delayed sleep onset.
  • Controlled-release (CR) melatonin formulations were superior for sleep maintenance.

Conclusions:

  • Controlled-release melatonin is a viable treatment for sleep maintenance issues in children with neurodevelopmental disorders.
  • Children may require higher melatonin doses compared to adults.
  • Further research into optimal CR melatonin dosing for pediatric sleep disorders is warranted.

Sleep-Wake Cycles

Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and  rapid eye movement (REM).

Management of Insomnia

The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...

Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response

Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...
