Insights

Melatonin effectively treats sleep-onset insomnia in pediatric patients with ADHD. This well-tolerated option shows mild adverse events, but larger trials are needed for optimal dosing and long-term safety.

Area of Science:

  • Pediatric Sleep Medicine
  • Neurodevelopmental Disorders
  • Pharmacology

Background:

  • Pediatric insomnia is common in children with attention-deficit/hyperactivity disorder (ADHD), negatively impacting academic and social functioning.
  • Standard treatments include behavioral therapy and optimizing ADHD medication, with pharmacotherapy considered as an adjunct.
  • Sleep-onset insomnia (SOI) is a specific sleep disorder prevalent in this population.

Purpose of the Study:

  • To evaluate the efficacy and safety of melatonin for treating insomnia in pediatric patients diagnosed with ADHD.
  • To synthesize current evidence on melatonin's role as an adjuvant therapy for sleep disturbances in children with ADHD.

Main Methods:

  • A comprehensive literature search was conducted across MEDLINE, EMBASE, and Scopus databases up to August 2009.
  • Included studies comprised randomized trials, safety studies, meta-analyses, and review articles focusing on melatonin, ADHD, and pediatric insomnia.
  • Data from identified English-language human studies were summarized to assess treatment outcomes and adverse events.

Main Results:

  • Four studies involving children aged 6-14 with ADHD and insomnia demonstrated improvements in sleep onset and latency with melatonin (3-6 mg doses).
  • Melatonin was found to regulate circadian rhythm sleep disorders, specifically sleep-onset insomnia.
  • Reported adverse events were transient and mild, indicating good tolerability.

Conclusions:

  • Melatonin appears to be a well-tolerated and effective treatment for chronic sleep-onset insomnia in pediatric patients with ADHD.
  • Further large-scale, well-designed clinical trials are necessary to establish optimal dosing and confirm long-term safety.
  • The use of regulated melatonin products is recommended for consistent efficacy and safety.

Management of Insomnia01:19

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...
Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.

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...
Insomnia01:27

Insomnia

Insomnia is a prevalent sleep disorder characterized by difficulty falling asleep, frequent awakenings during the night, and waking up too early without being able to return to sleep. People with insomnia often experience these disruptions at least three nights a week for at least one month. Chronic insomnia, which lasts for at least three months, can lead to increased anxiety, which in turn can worsen sleep difficulties, creating a cycle of sleeplessness and stress.

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...
Narcolepsy01:07

Narcolepsy

Narcolepsy is a chronic sleep disorder characterized by pervasive, uncontrolled sleepiness and other sleep disturbances. One of its hallmark symptoms is an abrupt transition to REM sleep upon falling asleep, which causes symptoms typically associated with this phase to occur unexpectedly during wakefulness. These include the following symptoms, which typically last from a minute or two to half an hour.
