Summary
Melatonin poison center calls primarily involved young children (<6 years) with unintentional exposures. Older individuals experienced more adverse effects, requiring healthcare facility management.
Area of Science:
- Toxicology
- Public Health
- Pharmacology
Background:
- Melatonin is widely used in the US for circadian rhythm regulation.
- Limited data exists on public melatonin use and associated adverse effects.
- Poison center data offers insights into substance exposures.
Purpose of the Study:
- To analyze patterns of melatonin-related calls to Texas poison centers from 1998-2003.
- To identify demographics, exposure circumstances, and outcomes of melatonin ingestions.
- To characterize adverse effects and management of melatonin exposures.
Main Methods:
- Retrospective analysis of all melatonin calls to the Texas Poison Center Network (1998-2003).
- Data extraction included patient age, sex, exposure intent, management site, and outcome.
- Statistical analysis of demographic and clinical data.
Main Results:
- 779 human melatonin exposures were identified.
- The majority (59.1%) involved children under 6 years.
- Younger children had higher rates of unintentional exposure and no clinical effects, often managed outside healthcare facilities.
- Older patients showed increased adverse effects and healthcare utilization.
Conclusions:
- Melatonin exposures reported to poison centers predominantly affect young children.
- Exposure characteristics and outcomes differ significantly by age group.
- Findings highlight the need for age-specific safety information regarding melatonin use.

01:19Pharmacovigilance
Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.

01:19Management 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...
01:17Sedatives 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...

01:24Drug Toxicity: Dose-Dependent Reactions
Drug toxicities can be stratified into pharmacological, pathological, or genotoxic based on their mechanisms. The incidence and severity of these toxicities generally increase with the drug's concentration in the body and exposure time.Pharmacological toxicity is evident when the therapeutic effects of drugs overshoot into adverse reactions in a predictable, dose-dependent manner. Central nervous system (CNS) depression from barbiturates is a classic example, with effects escalating from...
01:30Toxidromes: Clinical Features
Toxidromes are specific patterns of symptoms resulting from toxic substance exposure. They help in the identification and treatment of poisoning. The symptoms of each toxidrome group indicate poisoning by a certain class of chemicals or drugs.1. Sympathomimetic: Stimulates the sympathetic nervous system. Symptoms include agitation, increased heart rate (HR), blood pressure (BP), respiratory rate (RR), temperature, and pupil size. Drugs like cocaine and amphetamines, along with tremors and...
01:26Pharmaceutical Poisoning: Potential Scenarios
Pharmaceutical poisoning can occur through various channels, impacting an estimated 2 million hospitalized patients in the U.S. annually with serious adverse drug responses. These scenarios encompass both therapeutic uses, such as drug toxicity, where even standard dosages can lead to severe central nervous system depression, and non-therapeutic exposures, including accidental ingestion by children, and environmental and occupational exposures.Unintentional poisonings often involve exploratory...
