Insights

Many pediatric patients receive medications that are not specifically licensed for children (unlicensed) or used outside their approved indications (off-label). A study found that 42% of ambulatory children received such medications, highlighting a significant gap in pediatric drug safety.

Area of Science:

  • Pediatric Pharmacology
  • Drug Utilization Research
  • Public Health

Background:

  • Many medications lack established optimal dosage, safety, and efficacy standards for pediatric use.
  • A significant number of hospitalized children receive medications off-label or unlicensed.
  • The prevalence of off-label and unlicensed medication use in ambulatory pediatric populations is largely unknown.

Purpose of the Study:

  • To quantify the extent of unlicensed and off-label medication use in a general pediatrics ambulatory hospital unit in Israel.
  • To identify patterns and reasons for non-standard medication use in children treated in outpatient settings.

Main Methods:

  • Retrospective analysis of 132 outpatient children's medical records.
  • Data collected from the General Pediatrics Ambulatory Unit at Soroka Medical Center, Beer Sheva.
  • Prescriptions reviewed for adherence to licensing and approved indications.

Main Results:

  • Of 222 prescriptions, one-third were either unlicensed (8%) or off-label (26%).
  • Common reasons for off-label use included incorrect dosage and age indications.
  • All 18 instances of unlicensed use involved modifying licensed drugs, such as crushing tablets for suspensions.
  • A total of 42% of children received at least one medication that was off-label and/or unlicensed.

Conclusions:

  • Off-label medication use was more prevalent than unlicensed use in this ambulatory pediatric cohort.
  • Further research is essential to determine the full scope of unapproved drug use in both hospitalized and ambulatory pediatric patients in Israel.
  • Recent Ministry of Health recommendations represent a crucial initial step towards addressing pediatric medication safety internationally.

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 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...

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...

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...

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...
