3D Printing Pharmaceuticals for Personalized Medicine

This review article aims to provide insights into 3D printing technology and its various applications in the pharmaceutical industry, including the creation of medical devices, personalized medications, multi-drug formulations, and more. It offers advantages like customization, improved pre-operative planning, and new drug delivery systems, but also faces challenges related to quality control and regulation, including material selection, process validation, sterilization, and scalability. In light of these advancements, regulatory bodies are updating their guidelines to maintain safety and efficacy. The article discusses several prevalent methods of 3D printing in pharmaceuticals and compares these with conventional manufacturing, highlighting the differences between the two approaches. It illustrates how 3D printing can benefit a range of patients, including children, the elderly, women, those with visual impairments, and individuals with chronic illnesses. Furthermore, the technology has multiple applications such as personalized medicines and dosage forms, microneedles, nanosuspensions, implants, polypills, complex oral solid dosage formulations, and even the digitization of pharmacies. Looking forward, the integration of artificial intelligence, nanotechnology, and Four-Dimensional (4D) printing may lead to more sophisticated medical devices and enhance disease management and outcomes. While 3D printing represents significant innovation in the pharmaceutical industry, concerns regarding scalability and regulatory issues persist. Nevertheless, this technology is poised to greatly influence healthcare delivery in the coming decades, along with shifts in global research and regulatory frameworks.
