3D printing creates personalized gel medications for preterm infants, improving dosing accuracy and safety. This novel approach ensures reliable drug delivery, overcoming limitations of manual dose adjustments.
Area of Science:
- Pharmaceutical Technology
- Biomaterials Science
- Neonatal Medicine
Background:
- Manual dose adjustments in neonates are prone to errors, contamination, and reduced precision.
- Optimizing therapeutic outcomes requires accurate drug delivery, especially for vulnerable populations like preterm infants.
- Existing methods for pediatric dosing lack the personalization needed for optimal patient care.
Purpose of the Study:
- To develop and evaluate personalized, gel-based caffeine dosage forms using semi-solid extrusion 3D printing (SSE 3DP).
- To assess the precision, reproducibility, and drug release characteristics of the 3D-printed dosage forms.
- To demonstrate the potential of SSE 3DP for tailored neonatal medication.
Main Methods:
- Utilized agar and hydroxypropyl methylcellulose to formulate hydrogels with optimal rheological properties for SSE 3DP.
- Designed and printed personalized caffeine gel dosage forms with precise volume and content adjustments for a specific neonate.
- Conducted reproducibility assessments across three production batches and performed forced degradation studies.
Main Results:
- The hydrogel formulation exhibited excellent printability and shape retention.
- Achieved high caffeine recovery (103.46%) in a personalized dose, demonstrating precise drug content control.
- Production batches showed minimal variability, confirming process reproducibility.
- Degradation studies indicated caffeine's chemical integrity within the gel matrix.
- Printed dosage forms exhibited immediate-release profiles, with >80% caffeine released within 45 minutes.
Conclusions:
- Semi-solid extrusion 3D printing offers a precise and reproducible method for creating personalized gel-based drug delivery systems.
- This technology overcomes the limitations of traditional manual dosing, enhancing safety and efficacy in neonatal care.
- 3D-printed gel formulations hold significant promise for tailored pharmaceutical solutions, particularly for preterm infants.
