3D Printing In Pharmaceutics: Technologies, Applications, Personalized Medicine and Future Perspectives

Abstract

Three-dimensional printing, also known as manufacturing, has become an important way to create medicines with a level of flexibility that is hard to get with older ways of making them. Making each unit with the same size and ingredients 3D printing uses a digital design to create a product one layer at a time. This allows changes in dose, shape, inside structure types of medicine used and how the medicine is released all based on what the patient needs. Recent studies in medicine have looked at types of 3D printing. These include systems that push out materials like fused deposition modelling and semi-solid extrusion. Other methods use powder, like binder jetting and selective laser sintering. There are also methods that use light, like stereolithography. Inkjet printing and pressure-assisted microsyringe systems have also been studied for making medicine structures. These tools have been used to make tablets that release medicine quickly or over time multi-dose pills, medicines that dissolve quickly in the mouth implants, tiny needles, patches that go on the skin, medical devices and other ways to deliver medicine right where it is needed. The first 3D-printed tablet that got FDA approval called Spritam showed that this kind of manufacturing can go from the lab to medicine production. There are still problems. These include whether the medicine and other ingredients work together if they stay the same when printed if they can be printed well if the amount of medicine is the same each time if the process can be done the way each time how to make them clean how to check that the process works, how to control it for rules and the need for materials that are good enough for medicine. This review talks about the ideas of making medicine with 3D printing the main methods used what materials and formulas are needed, how they are used in medicine and for custom treatments how to make sure they are good and follow rules what is good about them what is not so good and what might come next. The information comes from reviews and is written in a simple academic style that is good, for a pharmacy report or the beginning of a thesis.
