Application of 3D Printing in Pharmaceutical Sciences, and Evaluation of Administration Routes for Drug-Loaded Composites

3D printing is novel approach in pharmaceutical field, but its usage has not yet fully established. This method can promote drug therapy and overcome some traditional treatment challenges in different ways that are discussed at this paper. "One-size-fits-all", Large-scale production, and less patient and physician acceptability are some limitations that we will encounter in traditional therapy. Three-dimensional printing of pharmaceutical products, is a versatile technology that needs specific attention. droplet-based, extrusion-based, and laser-assisted 3D printers are three main techniques that can be used in this field. The limitations and advantages of this method are also discussed, highlighting potential innovative pathways towards the possibility of drug carriers’ usage in ink formulas. The administration pathway of drug-loaded composites is another important issue in drug treatment strategies that has been discussed here. Oral drug delivery as a convenient method of systemic drug administration with great patient preference, is introduced as a most prevalent pathway that has been studies about 3D printed medicines. Finally, essential ethics and future directions of 3D printing in the pharmaceutical and healthcare industries are outlined.
