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.
