Insights

Preterm infants frequently receive medications containing potentially toxic excipients like ethanol and propylene glycol. Infants with chronic lung disease (CLD) faced higher exposure levels, necessitating strategies to reduce this toxic load.

Area of Science:

  • Neonatal pharmacology
  • Pediatric toxicology
  • Clinical pharmacy

Background:

  • Limited data exists on excipient exposure in preterm infants during clinical care.
  • Excipients are inactive ingredients in medications, but can have physiological effects.

Purpose of the Study:

  • To quantify excipient exposure in preterm infants at a single center.
  • To assess the impact of chronic lung disease (CLD) on excipient exposure.

Main Methods:

  • Retrospective analysis of drug charts for infants receiving oral liquid medications.
  • Study included infants born <30 weeks gestation or <1500g at birth.
  • Focused on infants managed at the Leicester Neonatal Service.

Main Results:

  • Infants were exposed to over 20 excipients, including potentially neurotoxic ethanol and propylene glycol.
  • Infants with CLD showed higher concentrations of these toxins.
  • High sorbitol exposure exceeded adult recommended guidelines in some cases.

Conclusions:

  • Preterm infants commonly encounter potentially toxic excipients in medications.
  • Higher exposure levels were observed in infants with CLD.
  • Urgent development of strategies to minimize excipient exposure in preterm infants is needed.

Teratogenicity01:07

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
Drug Toxicity: Dose-Dependent Reactions01:24

Drug Toxicity: Dose-Dependent Reactions

Drug toxicities can be stratified into pharmacological, pathological, or genotoxic based on their mechanisms. The incidence and severity of these toxicities generally increase with the drug's concentration in the body and exposure time.Pharmacological toxicity is evident when the therapeutic effects of drugs overshoot into adverse reactions in a predictable, dose-dependent manner. Central nervous system (CNS) depression from barbiturates is a classic example, with effects escalating from...
Drug Toxicity: Risk factors01:24

Drug Toxicity: Risk factors

Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...
Pharmaceutical Poisoning: Potential Scenarios01:26

Pharmaceutical Poisoning: Potential Scenarios

Pharmaceutical poisoning can occur through various channels, impacting an estimated 2 million hospitalized patients in the U.S. annually with serious adverse drug responses. These scenarios encompass both therapeutic uses, such as drug toxicity, where even standard dosages can lead to severe central nervous system depression, and non-therapeutic exposures, including accidental ingestion by children, and environmental and occupational exposures.Unintentional poisonings often involve exploratory...

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics

Respiratory symptoms, such as congestion and cough, commonly accompany respiratory tract conditions. Various medications, such as antitussives, expectorants, and mucolytics, play crucial roles in providing relief.
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla.  Benzonatate operates peripherally within the respiratory tract by anesthetizing...
Types of Toxins01:36

Types of Toxins

Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.
Environmental pollutants like...
