Drug Delivery System

Drug delivery is the method or process of administering a pharmaceutical compound to achieve a therapeutic effect in humans or animals. For the treatment of human diseases, nasal and pulmonary routes of drug delivery are gaining increasing importance. These routes provide promising alternatives to parenteral drug delivery particularly for peptide and protein therapeutics. For this purpose, several drug delivery systems have been formulated and are being investigated for nasal and pulmonary delivery. These include liposomes, proliposomes, microspheres, gels, prodrugs, cyclodextrins, among others. Nasal and respiratory organ routes of drug delivery are gaining importance for the treatment of human diseases. These routes give promising alternatives to drug delivery significantly for amide and super molecule medicine. For this purpose, many drug delivery systems are developed and are researching on nasal and respiratory organ delivery. These embrace liposomes, proliposomes, microspheres, gels, prodrugs, cyclodextrins among others. Nanoparticles composed of perishable polymers show assurance in fulfilling the tight needs placed on these delivery systems, like ability to be transferred into aerosol, stability against forces generated throughout aerosolization, biocompatibility.
