Excipients are critically important in converting active pharmaceutical ingredients (API) into drug products that have optimal stability, bioavailability, manufacturability, duration of action, and therapeutic benefits. They will play even greater roles in the future to enable drug targeting, delivery of biotech products and vaccines, gene therapy, continuous manufacturing, 3D printing, and so forth. This commentary describes the author’s experience in teaching a graduate course on excipients at St. John’s University to train students on optimal selection and appropriate use of excipients in formulating dosage forms and development of drug delivery systems. The course is offered in 15 two-hour sessions over a semester, and the course materials are divided into 13 modules on chemistry of different classes of polymeric and non-polymeric excipients and their application in dosage form development, including the use as solubilizing agents, lyophilizing agents, cryoprotectants, buffers, biodegradable materials, and carriers for amorphous solid dispersions and 3D printing. The development of coprocessed excipients, the need for new excipients, and the regulatory aspects of excipients are also covered. The course includes presentations by guest speakers from the industry, and the students also watch virtual presentations from experts that are publicly available from the internet. It is a popular course at St. John’s University taken by all graduate students in the pharmaceutics program. It is recommended that such courses are introduced in other pharmacy schools and academic institutions. The course may be adapted to meet specific needs of different academic programs. Professional associations, such as AAPS and CRS, industry groups like IPEC, and the pharmaceutical industry may be able to help in introducing such courses by providing lecture materials and guest lecturers.
