Prescription, Nonprescription and Orphan Drugs

1.3K
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 Excretion

342
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

555
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

398
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,...

Factors Affecting Drug Response: Overview

3.2K
When it comes to infants and young children, they are typically administered smaller doses of medication in comparison to adults. This is primarily because their organ functions still need to fully develop, meaning their bodies are not as efficient at metabolizing or eliminating drugs. Additionally, their blood-brain barrier is more permeable than in adults. As a result, high concentrations of drugs can easily penetrate the central nervous system (CNS), potentially leading to neurological...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

503
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...

Area of Science:

  • Pediatric Pharmacology
  • Drug Safety and Regulation

Background:

  • Clinicians frequently prescribe medications off-label or unlicensed in pediatric populations due to a lack of approved pediatric prescribing information.
  • This practice increases the risk of adverse drug reactions (ADRs) and improper dosing from insufficient safety and efficacy data.

Purpose of the Study:

  • To review worldwide rates of off-label and unlicensed drug use in pediatric patients.
  • To summarize associated adverse drug reactions (ADRs).
  • To discuss current regulatory provisions and propose solutions for safe pediatric medication use.

Main Methods:

  • Conducted literature searches to identify studies on unlicensed or off-label drug use in pediatric populations.
  • Acknowledged variability in definitions of off-label and unlicensed drug use across studies.

Main Results:

  • Included 14 studies from various countries, categorized by patient setting (neonatal intensive care, pediatric wards, hospitalized, outpatient).
  • Reported high prevalence rates for off-label drug use (9%–78.7%) and unlicensed drug use (0.3%–35%) across different pediatric settings.

Conclusions:

  • Cooperation among healthcare professionals, patients, caregivers, regulatory bodies, and industry is crucial to mitigate risks associated with pediatric drug use.
  • Incentives for pediatric clinical trials, such as market exclusivity, and strengthened legislation and pharmacovigilance are needed to improve drug safety and research in children.
