Pharmacokinetics in Pediatric Patients: Drug Excretion01:26

Pharmacokinetics in Pediatric Patients: Drug Excretion

117
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...

Pharmacokinetics in Pediatric Patients: Drug Metabolism

93
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...

Combination Therapies and Personalized Medicine

5.6K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Pharmacokinetics in Pediatric Patients: Drug Distribution

141
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

121
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...

    Summary

    Whole-genome sequencing in pediatric precision medicine identified actionable genomic alterations in over 70% of childhood cancer patients. Matched therapies led to positive responses in nearly one-third of these children, highlighting a promising treatment avenue.

    Area of Science:

    • Genomic medicine
    • Pediatric oncology

    Background:

    • Comprehensive genomic profiling (CGP) using whole-genome sequencing (WGS) is a key strategy in pediatric precision medicine.
    • The Australian Zero Childhood Cancer Precision Medicine Program applied CGP to identify genomic alterations in children with cancer.

    Discussion:

    • CGP identified potentially targetable genomic alterations in over 70% of pediatric cancer patients.
    • Nearly one-third of patients receiving therapy matched to their genomic profile showed a positive response.

    Key Insights:

    • WGS enables the identification of a high proportion of actionable genomic alterations in pediatric cancers.
    • Genomic-guided therapy demonstrates clinical benefit in a significant subset of children with cancer.

    Outlook:
