Pharmacy 3D printing

Abstract A significant limitation of the “one size fits all” medication approach is the lack of consideration for special population groups. 3D printing technology has revolutionised the landscape of pharmaceuticals and pharmacy practice, playing an integral role in enabling on-demand production of customised medication. Compared to traditional pharmaceutical processes, 3D printing has major advantages in producing tailored dosage forms with unique drug release mechanisms. Moreover, this technology has enabled the combination of multiple drugs in a single formulation addressing key issues of medication burden. Development of 3D printing in clinical applications and large-scale pharmaceutical manufacturing has substantially increased in recent years. This review focuses on the emergence of extrusion-based 3D printing, particularly semi solid extrusion, fused deposition modelling and direct powder extrusion, which are currently the most commonly studied in pharmacy practice. The concept of each technique is summarised, with examples of current and potential applications. Next, recent advancements in the 3D printer market and pharmacist perceptions are discussed. Finally, the benefits, challenges and prospects of pharmacy 3D printing technology are highlighted, emphasising its significance in changing the future of this field.
