Insights

Pediatric drug safety knowledge is limited. This study found varying rates of adverse drug reactions, with a potential signal for montelukast (leukotriene receptor antagonist) and psychiatric effects in young children.

Area of Science:

  • Pediatric Pharmacology
  • Drug Safety Surveillance
  • Pharmacovigilance

Background:

  • Limited data exists on the safety of drug treatments in pediatric populations.
  • Enhanced understanding of pediatric drug risks is crucial for accurate risk-benefit assessments.

Purpose of the Study:

  • To investigate the types and frequency of adverse drug reactions (ADRs) in children.
  • To analyze safety reports for commonly prescribed drug classes in pediatric outpatients.

Main Methods:

  • Examined individual case safety reports (ICSRs) for the top 30 drug groups by defined daily doses (DDDs) in children (<15 years) in 2005.
  • Conducted descriptive analyses of reported adverse drug reactions.

Main Results:

  • ICSRs per million DDDs varied significantly across drug groups (0-24).
  • The highest rate was observed for montelukast (leukotriene receptor antagonist, R03DC).
  • Psychiatric adverse drug reactions were most frequent in children under 5 years treated with montelukast.

Conclusions:

  • The frequency of ICSRs per million DDDs differs among drug groups in pediatric patients.
  • A potential safety signal for montelukast associated with psychiatric adverse drug reactions in children warrants further investigation.

Pharmacovigilance01:19

Pharmacovigilance

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.
In some cases, there...

Pharmaceutical 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...
Drug Regulation01:25

Drug Regulation

Drug regulation encompasses the management of drug usage by evaluating its safety and efficacy through assessments conducted by regulatory authorities. Regrettably, the history of drug regulation is marred by several catastrophic events. One such incident is the Elixir Sulfanilamide tragedy, in which the toxic compound diethyl glycol was included in a sweet-tasting medication, leading to numerous fatalities. This event prompted the enactment of the Food, Drug, and Cosmetic Act in 1938. Under...
Drug Toxicity: Risk factors01:24

Drug Toxicity: Risk factors

Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

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...
