Ultrasound conductive targeted drug delivery Ultrasound conductive targeted drug delivery therapy is a new drug therapy technology that has emerged in recent years. It is through physical means so that the drug through the skin into the body of diseased tissues and organs, directly play a role in drug therapy. It is called the third generation of drug delivery method by the medical profession. Its basic principle is: the use of laser microporous, electroporous, ultrasonic cavitation and other modern high-tech means, in a certain range and depth of the skin and tissues of the drug permeability greatly increased, the formation of the drug into the target organ of the artificial biological channel, in a specific kinetic energy drive, so that the drug particles along the biological channel through the skin, tissues and peripheral membranes, directional, quantitative, fixed-speed entry into the diseased tissues and organs, the target tissue The high concentration of drug infiltration area is formed, which can directly play the role of drug therapy and achieve the purpose of targeted therapy. Ultrasound conductive targeted drug delivery technology than the traditional oral and injection methods have many advantages: (1) fast drug permeability, the drug directly to the lesion; (2) can realize the positioning, quantitative and fixed-speed drug delivery, the formation of drug in the lesion of the local high-concentration area, increase the role of drugs, thereby improving the efficacy; (3) greatly improve the bioavailability of drugs, reduce the total amount of drugs (1 / 5 of the conventional dosage, 1/3) to avoid toxic side effects; (4) greatly improve drug bioavailability, reduce the total amount of drugs (1/5 of the conventional dosage) to avoid Toxic side effects; (4) stable and long-lasting efficacy, 2-3 times longer than oral medication; (5) wide range of adaptability, in addition to chemical drugs, but also through the large molecules of biological preparations and colloidal particles of traditional Chinese medicine ingredients; (6) painless, non-invasive, simple and convenient.
