Insights

In 2007, over half of children in British Columbia received at least one prescription. Drug dispensing patterns varied significantly between British Columbia, the US, and Europe, particularly for psychoanaleptics.

Area of Science:

  • Pediatric pharmacology
  • Epidemiology
  • Health services research

Background:

  • Population-based drug utilization databases are crucial for epidemiological studies but are scarce.
  • This study addresses the need for comprehensive data on pediatric medication use.

Purpose of the Study:

  • To examine prescription-dispensing rates in children in British Columbia (BC).
  • To compare pediatric medication dispensing in BC with the United States (US) and Europe.

Main Methods:

  • Utilized BC's provincial outpatient prescription dispensing database for children aged 0-17 years (n=855,541) in 2007.
  • Classified all dispensed prescriptions using the Anatomical Therapeutic Chemical (ATC) system.
  • Calculated prevalence of drug dispensing by age group, gender, and therapeutic class.

Main Results:

  • Fifty-five percent of BC children received at least one prescription in 2007.
  • Commonly dispensed drug classes included antibacterials, dermatological corticosteroids, and respiratory medications.
  • Psychoanaleptic dispensing was 2-5 times higher than in Europe but 30% lower than in the US.

Conclusions:

  • Approximately half of BC children under 18 received a prescription in 2007.
  • Significant international variations in pediatric drug dispensing exist.
  • Further research is needed to explore factors influencing these disparities and their clinical outcomes.

Pharmacokinetics in Pediatric Patients: Drug Distribution

Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight, compared...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...

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...

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 Metabolism

In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses a challenge in...
Analysis of Population Pharmacokinetic Data01:12

Analysis of Population Pharmacokinetic Data

Analysis of population pharmacokinetic data involves studying the behavior of drugs within diverse populations to understand their pharmacokinetic parameters. Traditional pharmacokinetic methods typically involve collecting samples from a few individuals and estimating these parameters. While these methods are commonly used, they have limitations in capturing the variability in drug response among individuals or heterogeneous populations. Population pharmacokinetics is employed to address these...
