Making Medicines Baby Size: The Challenges in Bridging the Formulation Gap in Neonatal Medicine

Area of Science:

• Neonatal pharmacology and pharmaceutical sciences.
• Pediatric drug formulation and delivery.

Background:

• Pediatric drug formulation must be age-appropriate, safe, accurate, and developmentally suitable.
• Neonatal medication needs have been historically overlooked, particularly for preterm and term infants.

Purpose of the Study:

• To review the unique challenges in formulating medications for neonates compared to older pediatric populations.
• To highlight differences in care environment, dosing accuracy, administration routes, devices, and biopharmaceutics for neonates.
• To address regulatory hurdles in neonatal drug product development.

Main Methods:

• Literature review focusing on neonatal-specific pharmaceutical challenges.
• Analysis of factors influencing drug formulation and administration in neonates.
• Examination of biopharmaceutical and regulatory considerations.

Main Results:

• Neonates present distinct challenges in dose measurement, administration, and product acceptability.
• Environmental factors, patient/carer abilities, and specific neonatal biopharmaceutics impact formulation.
• Regulatory complexities further complicate the development of suitable neonatal medicines.

Conclusions:

• Addressing the unique needs of neonates is crucial for developing safe and effective medications.
• Overcoming formulation, administration, and regulatory challenges will improve neonatal patient care.
• Further research and development are needed to support clinically relevant neonatal drug products.
