Personalized Drug Delivery with the Use of Modern 3D Printing Technology

One of the important goals of the pharmaceutical indusry is to increase the therapeutic efectiveness of drugs for  patients and reduce their side efects. In order to fulfll these targets, the drugs should be prescribed to each patient individually and in accordance with the patient's genetic information, because in each patient, the amount of drug absorption, the time that drug reaches the target tissue and the efect of drug on the patient's organ are diferent. This clearly shows the importance of personalized medicine. Medication in personalized medicine leads to patient comfort and adaptation. The production of personalized drugs with 3D printing technology has been possible, which has  received a lot of attention in recent years. Using this technology, it is possible to design and made drugs with diferent shapes and color for children and load some drugs in one dosage (polypill) for elderly people. Also, using this  technology, the drug release pattern can be adjused by changing the thickness or type of polymer layer. The drug  release profle can be designed in such a way that each drug in polypill has special release pattern. In this article, after explaining the importance of personalized drug delivery, some encapsulated drugs in polymeric carriers are discussed. Then, some new drug delivery sysems, such as wound dressings and microsyringes produced with this technology in recent years, are briefy reviewed.
