Development of Pyro-Drive Jet Injector With Controllable Jet Pressure

open access: yesJournal of Pharmaceutical Sciences, 2019
Various jet injectors have been developed and used for the effective and efficient administration of drugs. Jet injections overcome the limitations of other drug delivery methods, such as ablation, iontophoresis, electroporation, sonophoresis, and microneedles, because jet injection is not limited by the diffusion rates of different drugs.
