The potential of three-dimensional printing for pediatric oral solid dosage forms.

Pediatric patients often require individualized dosing of medicine due to their unique pharmacokinetic and developmental characteristics. Current methods for tailoring the dose of pediatric medications, such as tablet splitting or compounding liquid formulations, have limitations in terms of dosing accuracy and palatability. This paper explores the potential of 3D printing as a solution to address the challenges and provide tailored doses of medication for each pediatric patient.

Development of immediate release 3D-printed dosage forms for a poorly water-soluble drug by fused deposition modeling: Study of morphology, solid state and dissolution.

3D-printing technologies such as Fused Deposition Modeling (FDM) bring a unique opportunity for personalized and flexible near-patient production of pharmaceuticals, potentially improving safety and efficacy for some medications. However, FDM-printed tablets often exhibit tendency for slow dissolution due to polymer erosion-based dissolution mechanisms. Development of immediate release (IR) 3D-printed dosage with poorly water-soluble compounds is even more challenging but necessary to ensure wide applicability of the technology within pharmaceutical development portfolios.

Development of immediate release (IR) 3D-printed oral dosage forms with focus on industrial relevance.

Pharmaceutical 3D-printing represents a potentially new dosing and manufacturing approach for the pharmaceutical industry, with unique opportunities for personalization of dosage strengths. Fused deposition modelling (FDM) is a 3D-printing technique, which presents advantages for decentralized on-site manufacturing in hospitals and pharmacies. This study introduces industrially relevant development of formulations for filaments with the required mechanical properties to be 3D-printable and providing immediate release (IR) dosage forms using safe materials approved also for pediatric use.

Simplification of fused deposition modeling 3D-printing paradigm: Feasibility of 1-step direct powder printing for immediate release dosage form production.

Direct powder three-dimensional (3D)-printing (DPP) of tablets to simplify fused deposition modelling (FDM) was explored. The FDM paradigm involving hot-melt extrusion for making 3D-printable drug-loaded filaments as intermediate products for tablet manufacturing has been gaining attention for the decentralized on-site production of personalized dosage forms. For direct 3D-printing, powder blends were loaded into a cartridge-like head and were successfully printed with honeycomb design following heating of the extrusion cartridge.
