SUMMARY
The importance of personalized treatment is drastically growing since the awareness of people’s diversity, especially of the diversity of their organisms, is increasing every year. Discoveries in genetics and their influence on the development of some diseases confirm the value of such treatment. Therefore, current research in pharmaceutical technology is increasingly leaning towards developing and optimizing dosage forms suitable for it. In this regard, more and more researchers are focusing on the development of 2D printing technology. Its convenience, the possibility of its extensive use, and the possibility for simple drug concertation adjustment are bringing this technology to the forefront. The drug inject printing principle is the same as printing text documents, yet the ink is replaced by drug dispersion, while paper sheets are replaced by various biocompatible substrates that serve as oral dosage forms. For this purpose, different types of printers meeting different specifications can be used to print drugs successfully. The advantages of such technology are the rapid production of personalized medicine and the ability to combine several different drugs simultaneously in a single dosage form. Despite all the advantages of printing technology, there are still some challenges that must be addressed before such a drug delivery system will reach the market and be available to patients.
