Needle free injection technology (NFIT) is a broad concept which includes a wide range of approaches, formulations, technologies, and systems for transporting the delivery system that drive drugs through the skin like pressure by gas or electrophoresis which delivers the drug into the skin. Today, they are a steadily developing technology that promises to make the administration of medicine more efficient and less painful .Needle-free injection techniques can be used regulate vaccines and medications in the many other industry.
It Prevent skin hazards and also does not cause problem of bleeding or bruising and minimal skin response. It also avoids problems of any effect of shearing and results in less pain, and is strongly preferred by patients. Additional benefits include very fast injection compared with conventional needles and no needle disposal issues, this technology makes fast drug delivery and better reproducibility as compared to intrusive drug delivery systems and hence enhances bio availability when compared with intrusive drug delivery systems, and Better drug stability as it is delivered in dry powder form especially for water sensitive drugs
There are three types of Free Injections i.e. System Power Injections, Liquid Injections, Depot or Projectile Injection and this new technology is very convenience as it is easier to train and reduces sharp waste delivers injection in a fraction of second ,no risk of needle stick injury. Not only it can benefit the pharmaceutical industry in increasing product sales, it has the added potential to increase compliance with dosage regimens and improved outcomes.
PharmaJet,Medical International Technology, Inc., INJEX Pharma AG, National Medical Products Inc., European Pharma Group, Antares Pharma, Inc., Endo International plc, Valeritas Inc ,Penject Corporation, Crossjec and Bioject Medical Technologies Inc these are the few key vendors. Companies are working on producing devices that are safer and easier to use. They are also working on alternatives which can deliver even more types of medicines. Inhalers are being improved as are nasal sprays, forced air injectors and patches. In the future, other foods may be genetically enhanced to deliver vaccines and other drugs.
How It Works?
A jet injector is a type of medical injecting syringe that makes use of high-pressure narrow jet of the injection liquid which penetrates into the epidermis. Jet injectors are used for mass vaccination and as an alternative to needle syringes for diabetics to inject insulin. Medication is driven at high speed through a tiny orifice through which a fine stream of medication penetrates the tissue.
