Cornell University researchers have developed an ultrafast-dissolving nanofiber film that could change how patients manage pain. This technology specifically targets children and seniors who face challenges when swallowing traditional tablets. By using electrospinning, the team created a thin film that functions like a common breath strip. This material releases 90 percent of its drug contents in under two seconds.
The study, led by Tamer Uyar in the College of Human Ecology, focused on a combination of aspirin, paracetamol, and caffeine. These ingredients match the profile of common headache treatments. Unlike traditional manufacturing methods that require organic solvents, this production process relies on water and cyclodextrin, which is a starch-derived cyclic oligosaccharide. This ensures a cleaner production cycle while maintaining high scalability for commercial use.
The performance of the film exceeded the performance of standard powder formulations. In comparative tests, the film released medication three times faster than the powder version. The researchers note that the fiber matrix improves drug solubility and masks unpleasant tastes, providing a practical advantage for patients. This work demonstrates a new method for delivering multiple medications through a single, easy-to-use delivery system.
The project utilized facilities at the Cornell Center for Materials Research and the Cornell NMR Facility. With this proof of concept established, the team intends to expand the technology to other drug combinations. This advancement offers a direct path toward more efficient medical administration for patients with specific accessibility needs.
