Insights

Low-dose oral erythromycin improved feeding tolerance and reduced parenteral nutrition duration in preterm infants over 32 weeks gestation. However, it did not show similar benefits for infants younger than 32 weeks.

Area of Science:

  • Neonatology
  • Pediatric Gastroenterology
  • Pharmacology

Background:

  • Feeding intolerance is a common complication in preterm infants.
  • Early establishment of enteral feeding is crucial for infant growth and development.
  • Parenteral nutrition (PN) is often required but associated with risks.

Purpose of the Study:

  • To assess the efficacy of low-dose oral erythromycin in treating feeding intolerance in preterm infants.
  • To determine if erythromycin can accelerate the achievement of full enteral feeding.
  • To evaluate the impact of erythromycin on the duration of parenteral nutrition.

Main Methods:

  • A prospective, double-blind, randomized, placebo-controlled trial was conducted.
  • Sixty preterm infants with feeding intolerance were randomized to receive either oral erythromycin (1 mg/kg every 8 h) or placebo.
  • Infants were stratified by gestational age (>32 weeks or ≤32 weeks), and outcomes included time to full enteral feeding and duration of PN.

Main Results:

  • In infants with gestational age >32 weeks, erythromycin significantly reduced the time to full enteral feeding (10.5 vs 16.3 days) and the duration of PN.
  • Erythromycin also led to fewer gastric residuals in infants >32 weeks gestation.
  • No significant differences in feeding tolerance or PN duration were observed between erythromycin and placebo groups in infants ≤32 weeks gestation.

Conclusions:

  • Low-dose enteral erythromycin effectively improves feeding tolerance and shortens PN duration in preterm infants with gestational age >32 weeks.
  • The study did not demonstrate a similar benefit for younger preterm infants (≤32 weeks gestation).
  • Further research may be needed to explore erythromycin's role in specific subgroups of preterm infants.

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: 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...

Generic intravenous (IV) drugs are considered bioequivalent to their branded counterparts due to their 100% bioavailability upon administration. However, variations in stability among different drug products can significantly influence their therapeutic performance, even if they are pharmaceutically equivalent.Cefuroxime, a prophylactic antimicrobial, is often used as a single-dose IV injection for patients undergoing coronary artery bypass grafting surgery.

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: 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...
