Summary
Dosing medications for neonates is challenging due to limited data. New precision dosing strategies using pharmacokinetics and pharmacodynamics can optimize drug therapy and improve outcomes for critically ill infants.
Area of Science:
- Neonatal pharmacology
- Pharmacokinetics and pharmacodynamics
- Precision medicine
Background:
- Limited evidence exists for neonatal medication dosing, often relying on extrapolated adult/pediatric data.
- Current dosing methods may result in unsafe or ineffective drug administration in neonates.
- Critically ill neonates present unique challenges for drug therapy optimization.
Purpose of the Study:
- To review drug response factors in neonates, including prematurity and genetic polymorphisms.
- To assess current and emerging strategies for precision dosing in neonatal populations.
- To propose innovative pharmacokinetic/pharmacodynamic model-based approaches for optimizing neonatal medical therapy.
Main Methods:
- Review of existing literature on neonatal drug dosing, pharmacokinetics, and pharmacodynamics.
- Assessment of mass spectroscopy technology for rapid drug level analysis.
- Integration of population pharmacokinetic/pharmacodynamic models with sparse neonatal data and Bayesian analysis.
Main Results:
- Prematurity and genetic polymorphisms significantly impact drug response in neonates.
- Advanced modeling and electronic decision support tools enable timely dosing adjustments.
- Precision dosing approaches can optimize medical therapy and minimize adverse outcomes in neonates.
Conclusions:
- Innovative pharmacokinetic/pharmacodynamic model-based strategies offer a path toward precision dosing in neonates.
- Combining population pharmacology, Bayesian analysis, and electronic decision support is crucial.
- Overcoming implementation barriers is essential for widespread adoption of precision dosing in neonatal care.

301
The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.

01:29Drug Dosing: Infants and Children
306
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...

01:15Drug Dosing: Geriatric Patients
278
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

01:21Drug Dosing: Obese Patients
268
In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

01:25Drug Dosing in Renal Diseases: Dose Adjustments Based on Drug Clearance and Elimination Rate Constant
228
In patients with renal disease, dosage adjustments are necessary to maintain therapeutic plasma drug concentrations and prevent toxicity or subtherapeutic exposure. Renal impairment alters drug pharmacokinetics, especially in conditions like uremia, where changes such as prolonged elimination half-life and altered apparent volume of distribution can significantly affect drug disposition. These changes require careful modification of the dosing regimen to achieve the desired clinical...

Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.
