Raphas is developing a new concept of drug delivery system that overcomes the limitations of conventional transdermal delivery. Soluble microneedle patches, also called "painless injections", are a type of transdermal delivery system that delivers drugs efficiently by penetrating the skin with a needle as thin as a mosquito's proboscis. This new concept of drug delivery system eliminates pain, trauma, infection, fear, and repulsion, which are the main disadvantages of conventional syringes. Since this delivery system does not involve passing a drug through the gastrointestinal tract, it can be administered irrespective of pH, enzymes, foods, or gastrointestinal tract movements that affect drug absorption. It has other advantages of being simple to use and enabling long-term, continuous administration as well as easy control of blood concentration.
