Analysis and Evaluation of Modern Approaches to Development of Medical Drugs Using Micro- and Nanotechnologies

INTRODUCTION: TDespite the achievements of the modern medicine, use of some medical drugs (MDs) is associated with both the absence of a significant therapeutic effect due to peculiarities of the physico-chemical interaction in the internal environment of an organism, and with the adverse effect on organs and tissues. The advanced technologies of creation of micro- and nanoparticles will permit to improve pharmacokinetics and pharmacodynamics of the drug, its bioavailability and solubility, the ability of crossing blood-brain barriers, and to reduce undesirable systemic effects. MDs using micro- and nanoparticles, have a targeted effect on the focus of pathological lesion. An important additional advantage is a possibility of using micro- and nanoparticles in development of long-acting MDs. The main active substances immobilized to micro- and nanoparticles, open up new prospects for effective treatment of different pathological conditions (neoplasms, diseases of cardiovascular and central nervous system, inflammatory processes, wounds), and for realization of new imaging capabilities in foci of a pathological process, which is especially important in diagnostic procedures. CONCLUSION: The article presents a summary of the ideas of methods of micro- and nanoencapsulation, and assessments of the prospects for the development of drugs for the correction of pathological conditions using innovative technologies.
