Insights

Early introduction of lipid emulsions in preterm infants does not improve growth or reduce mortality. However, it does not increase complications, and specific lipid compositions may benefit fatty acid metabolism, though further research is needed.

Area of Science:

  • Neonatal Nutrition
  • Parenteral Nutrition
  • Lipid Metabolism

Background:

  • Lipid emulsions are vital for essential fatty acids and energy in infants receiving parenteral nutrition.
  • Optimal lipid composition and timing for premature infants remain debated to maximize benefits and minimize risks.

Purpose of the Study:

  • To review the evidence on early versus late lipid emulsion administration in preterm infants.
  • To examine the impact of different lipid emulsion compositions on peroxidation and fatty acid metabolism.
  • To assess the safety and efficacy of various lipid formulations in neonatal parenteral nutrition.

Main Methods:

  • Meta-analysis of studies comparing early versus late lipid emulsion administration.
  • In-vitro investigations on lipid peroxidation and fatty acid composition.
  • Review of studies on the influence of lipid emulsion composition on fatty acid metabolism.

Main Results:

  • Early lipid emulsion introduction did not improve short-term growth or reduce morbidity/mortality in preterm infants.
  • Early administration of lipid emulsions was not associated with increased complications.
  • In-vitro data suggest lipid peroxidation is linked to polyunsaturated fatty acid content and inversely to the alpha-tocopherol/polyunsaturated fatty acid ratio.
  • Medium-chain and long-chain triglyceride mixtures may enhance essential fatty acid incorporation compared to long-chain triglycerides alone.

Conclusions:

  • While lipid emulsion composition affects peroxidation and fatty acid metabolism, clinical outcome studies are necessary.
  • Further research is required to confirm the benefits of specific lipid formulations in neonatal parenteral nutrition.

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...

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...

Parenteral Drug Delivery Systems: Injectables, Implants, and Infusion Devices

Parenteral drug delivery systems play a crucial role in modern therapeutics by enabling the direct administration of drugs into the systemic circulation, bypassing the gastrointestinal tract. These systems are particularly valuable for poorly absorbed oral medications that are unstable in the digestive environment or require rapid onset or sustained therapeutic levels. Delivery is achieved through intravenous, intramuscular, or subcutaneous routes, each selected based on the drug's properties...

Bioavailability Enhancement: Drug Permeability Enhancement

After oral administration, poor permeability often limits the rate at which drugs are absorbed through the intestinal epithelium. Enhancing drug permeability is crucial for effective therapy, and several strategies have been developed to overcome this challenge.One effective strategy involves the use of lipid-based formulations. These formulations enhance dissolution and solubility, targeting physiological mechanisms to increase drug absorption. This includes stimulating bile salt secretion,...
