Introduction

Pain management and sedation also require careful consideration to avoid adverse effects, given the sensitivity of the neonatal nervous system. Dosing in neonates is typically based on weight and gestational age, with frequent adjustments needed due to rapid changes in body composition and organ function. There is a growing emphasis on the need for age-specific drug formulations and dosing guidelines to reduce the risk of medication errors and adverse drug reactions. The development of neonatal pharmacotherapy is ongoing, with research focused on optimizing drug efficacy and safety through improved understanding of neonatal physiology, advanced drug delivery systems, and personalized medicine approaches. In summary, neonatal drug therapy is a complex and evolving field that requires a careful balance between therapeutic efficacy and safety.

Discussion

Continuous research and adaptation of treatment protocols are essential to meet the needs of this vulnerable population. Neonatal drug therapy is a specialized branch of pharmacology that addresses the unique medical needs of newborns, particularly those in the critical first 28 days of life. This period, known as the neonatal period, is marked by significant physiological changes as infants adapt to life outside the womb. Premature and critically ill neonates are especially vulnerable, often requiring complex medical interventions, including the use of pharmacological agents to support their fragile systems. The administration of drugs in neonates presents a set of challenges that differ markedly from those encountered in older children and adults. The underdevelopment of organ systems, particularly the liver and kidneys, leads to significant differences in drug metabolism and excretion. These differences necessitate precise dosing and careful monitoring to avoid toxicity while ensuring therapeutic effectiveness. Neonatal pharmacotherapy encompasses a wide range of drugs, including antibiotics for treating infections, surfactants for managing respiratory distress syndrome, and anticonvulsants for controlling seizures. Additionally, the management of pain and sedation in neonates requires particular caution, given the heightened sensitivity of the neonatal nervous system. Despite the critical role of drugs in neonatal care, the field is still evolving. Many drugs used in neonatal care are not specifically approved for this population, leading to off-label use based on extrapolation from adult or pediatric data. This underscores the importance of ongoing research to better understand neonatal pharmacokinetics and pharmacodynamics, as well as the development of age-appropriate formulations and dosing guidelines. In this context, the study of neonatal drugs is essential not only for improving immediate clinical outcomes but also for ensuring long-term health and development. As neonatal care advances, the focus remains on refining drug therapy to enhance safety and efficacy, thereby providing the best possible care for this vulnerable population [1-4].

The administration of drugs in neonates is a delicate balance between therapeutic benefit and potential harm, driven by the unique physiological characteristics of newborns. In this discussion, we explore the key considerations, challenges, and emerging trends in neonatal pharmacotherapy. Neonates exhibit marked differences in drug absorption, distribution, metabolism, and excretion compared to older children and adults. The immaturity of the gastrointestinal tract affects oral drug absorption, while reduced muscle mass and blood flow influence intramuscular absorption. Drug distribution is altered by higher body water content and lower fat stores, impacting the volume of distribution for hydrophilic and lipophilic drugs, respectively. Due to the limited clinical trials conducted specifically in neonates, many drugs are used off-label in neonatal care. While this practice is often necessary, it highlights a critical gap in neonatal pharmacotherapy. The reliance on data from older populations can lead to suboptimal dosing and unexpected adverse reactions in neonates. Advancements in neonatal pharmacotherapy are increasingly focusing on personalized medicine and pharmacogenomics. Understanding the genetic factors that influence drug metabolism and response in neonates could lead to more individualized and effective treatments [5-7].

Additionally, the development of neonatal-specific drug formulations, such as liquid preparations and microdosed tablets, is a promising area of research that could improve dosing accuracy and patient outcomes. The ethical challenges of conducting clinical trials in neonates pose a significant barrier to advancing neonatal pharmacotherapy. Regulatory frameworks are evolving to encourage more research in this population while ensuring safety and ethical standards. Collaborative efforts between researchers, regulatory agencies, and pharmaceutical companies are crucial to overcoming these challenges and ensuring that neonates receive the best possible pharmacological care. For clinicians, staying informed about the latest developments in neonatal pharmacotherapy is vital. The theoretical framework for neonatal pharmacotherapy is rooted in understanding the profound physiological differences between neonates and older populations, and how these differences influence drug action and safety. The theory involves the integration of pharmacokinetics (PK), pharmacodynamics (PD), and developmental pharmacology, which together provide the basis for drug dosing, efficacy, and safety in the neonatal population. Developmental pharmacology is the study of how drug responses change with age, particularly during the neonatal period [8]. Neonates undergo rapid physiological changes as they transition from the intrauterine environment to independent life. These changes significantly impact drug absorption, distribution, metabolism, and excretion. The theory posits that as organs such as the liver and kidneys mature, there are corresponding changes in how drugs are processed, which must be accounted for in drug dosing and administration. In neonates, drug absorption is influenced by factors such as gastric pH, gastric emptying time, and enzyme activity in the gastrointestinal tract, all of which are immature at birth. The theory suggests that these factors lead to unpredictable absorption rates, particularly for orally administered drugs. An instrument measuring implementation readiness of skin-to-skin care for critically ill premature infants has been previously validated.

Conclusion

A group of experts reviewed the original instrument and adapted items based on existing research and face validity. The revised instrument was distributed to nurses and healthcare professionals caring for neonates with complex congenital heart disease at an international conference and word of mouth from August to December 2023. A total of 158 nurses and 65 healthcare professionals completed the survey. Cronbach's alpha demonstrated strong internal consistency (α = 0.96, 95%CI = 0.94–0.97). Exploratory factor analysis revealed a seven-factor solution provided the strongest fit. This instrument may serve as a useful tool for nurses aiming to enhance the uptake of skin-to-skin care for neonates with complex congenital heart disease.
