Needle free injection technology was developed to reduce the number of needle stick accidents and associated problems. Advantages over needle injections, their components and types such as powder injection, liquid injection, depot or projectile injection. This describes needle free injection technology involving the generation of force by using compressed gas upon actuation in order to deliver a drug at very high speed through a nozzle. It also describes injection methods that use a spring load jet injector, battery powdered jet injector, and gas powdered jet injector. An overview of marketed products, recent trends and other needleless drug delivery systems is given. Needle free injection technology is growing and has the potential to make the administration of medicine more efficient, safe and convenient.
