Insights

Potential drug-drug interactions (DDIs) were common in Nigerian pediatric outpatients, affecting 16.9% of patients. However, these drug-drug interactions were linked to few adverse drug events (ADEs).

Area of Science:

  • Pharmacovigilance
  • Clinical Pharmacy
  • Pediatric Pharmacology

Background:

  • Limited data exists on drug-drug interactions (DDIs) and adverse drug events (ADEs) in Nigerian pediatric populations.
  • Understanding DDI prevalence is crucial for patient safety in pediatric care.

Purpose of the Study:

  • To determine the incidence of potential DDIs among pediatric outpatients in Nigeria.
  • To assess the association between potential DDIs and reported ADEs in this demographic.

Main Methods:

  • A prospective clinical audit was conducted over three months in four Nigerian general hospitals.
  • Data on potential DDIs and documented ADEs were extracted from patient case files of 1233 eligible pediatric outpatients.

Main Results:

  • 16.9% of patients (208/1233) had prescriptions with at least one potential DDI, predominantly involving antimalarial combination therapies.
  • Commonly implicated drugs included promethazine, artemether/lumefantrine, and ciprofloxacin.
  • While potential DDIs were frequent, only 15 patients reported ADEs, and just 48 attended follow-up clinics.

Conclusions:

  • Potential DDIs are prevalent in Nigerian pediatric outpatients.
  • Despite the high exposure to potential DDIs, a low number of actual adverse drug events were reported.

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,...

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...

Factors Affecting Drug Response: Overview01:21

Factors Affecting Drug Response: Overview

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...
