Needleless injection technology was developed to reduce the number of needle-stick accidents and associated problems; easy to use, disposable and their use is expected to increase considerably. Self-administration is feasible with these devices. This technology is used to deliver not only drugs but also proteins, peptides, monoclonal antibodies, small molecules and vaccines. This review describes pre-requisites, comparison between hypodermic and needle free injections, manufacturing process, components, types and marketed products.
