Проблемы Использования Нанотехнологии В Фармакологии

The applications of nanotechnology to pharmacology are reviewed. The potential applications of biochips, nanosensors, bioreactors, neural stem cells, immune nanoparticles, biodegradable polymers, and convection-enhanced drug delivery in the diagnostics and treatment of diseases are discussed. Specific attention is given to developments in chemotherapeutic means, including advanced drug delivery systems and targeted nanotherapy, which will form the basis of the future nanomedicine. Numerous novel medicinal forms are discussed, including polymeric nanoparticles, nanotubes, micelles, liposomes, dendrimers, fullerenes, and hydrogels. In particular, highly stable glycosphyngolipid nanotubes and nanoliposomes are proposed as drug delivery systems. For this purpose, the model of stimulation of skin vasomotor reactions by nitroglycerin application is developed. The effect of nitroglycerin is shown to increase 1.5 times when used in the form of a dispersion with nanotubes as carriers and almost 2.5 times in the case of a dispersion with nanoliposomes as carriers. Nanotechnologically manufactured biologically active substances Apiton-25 (containing apis products) and Microhydrin (containing SiO2 nanoparticles, silicon hydrogen bonds Si-H, and free negative charges for free radical neutralization) have been studied. The results indicate that both Apiton-25 and Microhydrin upon peroral administration enhance the cyclic trial performance during prolonged submaximal exercise in endurance-trained cyclists.
