Insights

Off-label prescribing is common in Scottish primary care, affecting over a quarter of children. Dosing inaccuracies, particularly lower doses, were most frequent, alongside issues with age and formulation appropriateness.

Area of Science:

  • Pediatric Pharmacology
  • General Practice Research
  • Drug Utilization Studies

Background:

  • Off-label prescribing in children is a significant concern due to potential safety and efficacy issues.
  • Limited data exists on the extent and patterns of pediatric off-label prescribing in UK primary care.

Purpose of the Study:

  • To determine the prevalence and characteristics of off-label medication use in children within Scottish primary care.
  • To identify the main reasons for off-label prescribing in this pediatric population.

Main Methods:

  • A large-scale retrospective analysis of prescribing data from 161 general practices in Scotland.
  • Involved assessment of prescriptions for 167,865 children aged 0-16 years between November 1999 and October 2000.
  • Utilized data from the General Practice Administration System for Scotland (GPASS).

Main Results:

  • Over a quarter of children (26.1%) received at least one off-label prescription.
  • The most common off-label use involved incorrect dosage (lower or higher than recommended), particularly for antibiotics and antiasthmatics.
  • Prescribing outside recommended age ranges and formulations was less frequent.

Conclusions:

  • This study represents the most extensive analysis of pediatric off-label prescribing in UK primary care to date.
  • Factors contributing to off-label prescribing include outdated licensing information, lack of awareness, insufficient clinical trial data, and unavailability of suitable pediatric formulations.
  • Addressing these issues is crucial for improving the safe and effective use of medications in children.

Prescription, Nonprescription and Orphan Drugs

Prescription drugs require a prescription from a medical practitioner and can only be obtained from a pharmacy. They have many applications, including treating pain, anxiety, and hypertension.
The misuse and addiction to prescription drugs is a growing problem that can affect people of all age groups, specifically teenagers. This can happen when prescription medications are used in ways not intended by the prescriber, such as taking someone else's prescription or using medication for...

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 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: 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...

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 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...
