3D printing technology in drug delivery system / 国际药学研究杂志

ABSTRACT

Three-dimensional(3D)printing,a type of rapid prototyping technology,is based on a digital model file and prints layer-by-layer using adhesive materials,such as powdered metal or plastic. 3D printing has attracted much attention in the pharmaceutical field because of the various advantages,such as simple operation,good flexibility,high repeatability,wide adaptability,and more importantly,customized service. Currently,it is used in formulations of imme- diate release,sustained release,implants,etc. Recently,the integration of medical devices and drugs with 3D printing has been gaining popularity. This review not only summarizes the latest progress in techniques,materials,and pharma- ceutical dosage forms used in drug delivery system with 3D printing,but also analyzes its advantages and limitations, with the hope of providing reference for the development and application of 3D printing technology in drug delivery. This novel drug delivery system will bring new vitality to individualized medication.
