impact of nanotechnology in medicine

NCS is a simple guide to the evaluation of the risk of nanoparticles, but there are many other parameters playing a relevant role in nanotoxicity determination (Mller et al., 2011; Keck and Mller, 2013). Another related challenge is the development of a framework for the evaluation of the follow-on nanomedicines at the time of reference medicine patent expiration (Ehmann et al., 2013; Tinkle et al., 2014). 101, 183185. doi: 10.1208/s12249-010-9566-x, Rusyn, I., and Daston, G. P. (2010). Eur. doi: 10.1016/j.proeng.2015.01.284, Ossa, D. (2014). Accordingly, the primary phase is achieved in the native state of the nanomaterial, specifically, in its dry state. All these aspects will govern the characteristics of the interface between the nanomaterial and biological components and, consequently, promote different cellular fates (Nel et al., 2009; Kim et al., 2010; Albanese et al., 2012; Monopoli et al., 2012).

The particles visualization is preferentially performed using microscopy methods, which include several variations of these techniques. 377, 185198. The following characteristics should be a starting point to the characterization: particle size, shape and size distribution, aggregation and agglomeration state, crystal structure, specific surface area, porosity, chemical composition, surface chemistry, charge, photocatalytic activity, zeta potential, water solubility, dissolution rate/kinetics, and dustiness (McCall et al., 2013; Lin et al., 2014). Inorganic materials such as gold, iron and silica have been used to synthesize nanostructured materials for various drug delivery and imaging applications (Fig. One particular aspect of the nanomedicine field which has received a great deal of attention is the design and development of nanoparticulate nanomedicines (NNMs) for drug delivery (i.e., drug-containing nanoparticles). Consequently, the particle surface energy is increased, making the nanomaterials much more reactive. An increasing number of applications and products containing nanomaterials or at least with nano-based claims have become available. doi: 10.1126/science.1114397, Nel, A.

According to the FDA definition PAT is a system for designing, analzsing, and controlling manufacturing through timely measurements (i.e., during processing) of critical quality and performance attributes of raw and in-process materials and processes, with the goal of ensuring final product quality (FDA, 2014). doi: 10.1038/nnano.2012.207. Some efforts have been made in order to find a consensual definition due to the fact that nanomaterials possess novel physicochemical properties, different from those of their conventional bulk chemical equivalents, due to their small size. A stepwise comparison of bioequivalence, safety, quality, and efficacy, in relation to the reference medicine, which leads to therapeutic equivalence and consequently interchangeability, is required (Astier et al., 2017). These two processes of manufacturing are in the origin of different forms of particles termed primary particle, aggregate and agglomerate (Figure 1). This can lead to further subdivision in eight classes from I-B, I-NB, to IV-B and IV-NB (Mller et al., 2011; Keck and Mller, 2013). Pharmacol. The stress response is another example which can be analyzed by probes in the evaluation of the inflammatory response via enzyme linked immunosorbent assay are used (Kroll et al., 2009).

However, there is a big concern about the results of the experiments, because they were not performed following standard and harmonized protocols. Nanotoxicological classification system (NCS)a guide for the risk-benefit assessment of nanoparticulate drug delivery systems. A detailed definition of the acceptable limits for the CQA is very important, and these parameters must be identified and analyzed at the small-scale, in order to understand how the manufacturing process can change them: this will help the implementation of the larger scale. No use, distribution or reproduction is permitted which does not comply with these terms. The traditional manufacturing processes do not create three dimensional medicines in the nanometer scale. doi: 10.1016/j.ejpb.2008.08.009, Landsiedel, R., Ma-Hock, L., Wiench, K., Wohlleben, W., and Sauer, U. G. (2017). Nanomedicine is holding promising changes in clinical practice by the introduction of novel medicines for both diagnosis and treatment, having enabled to address unmet medical needs, by (i) integrating effective molecules that otherwise could not be used because of their high toxicity (e.g., Mepact), (ii) exploiting multiple mechanisms of action (e.g., Nanomag, multifunctional gels), (iii) maximizing efficacy (e.g., by increasing bioavailability) and reducing dose and toxicity, (iv) providing drug targeting, controlled and site specific release, favoring a preferential distribution within the body (e.g., in areas with cancer lesions) and improved transport across biological barriers (Chan, 2006; Mndez-Rojas et al., 2009; Zhang et al., 2012; Ossa, 2014). 45, 833842. For regulatory purposes, the biological nanomedicines are under the framework set by European Medicines Agency (EMA)1 This framework is a regulatory approach for the follow-on biological nanomedicines, which include recommendations for comparative quality, non-clinical and clinical studies (Mhlebach et al., 2015).

Nanotechnology in medicine and healthcare Nanomedicine is the term used to refer to the applications of nanotechnologies in medicine and healthcare. Nanomedicine involves the use of nanoscale materials, such . Another requirement for the introduction of medicines in the pharmaceutical market is the reproducibility of every batch produced. In turn, the nanotechnology methods for the development of nanomedicines bring new challenges for the current regulatory framework used. The adherence to the surface of membranes increases with the decrease of the size. 2 ). The lower size limit is used to distinguish atoms and molecules from particles (Lvestam et al., 2010). 76, 234261. The use of nanotechnology in the development of new medicines is now part of our research and in the European Union (EU) it has been recognized as a Key Enabling Technology, capable of providing new and innovative medical solution to address unmet medical needs (Bleeker et al., 2013; Ossa, 2014; Tinkle et al., 2014; Pita et al., 2016). Transmission Electron Microscopy (TEM), High-Resolution TEM, Scanning Electron Microscopy (SEM), cryo-SEM, Atomic Force Microscopy and Particle Tracking Analysis are just some of the examples. Distinct physiological outcomes are possible due to the different pathways for cell injury after the interaction between nanomaterials and cells and tissues (Nel et al., 2006; Arora et al., 2012; Azhdarzadeh et al., 2015). In turn, biodegradability was considered a required parameter in almost all pharmaceutical formulations. Rev. While clinical medicine targets health at the individual level, the mission of public . The evaluation of mitochondrial activity, the lactate dehydrogenase release from the cytosol by tretazolium salts and the detection of the biological marker Caspase-3 are some of the examples that imposes experimental variability in this analysis. Quality-by-Design (QbD), supported by Process Analytical Technologies (PAT) is one of the pharmaceutical development approaches that were recognized for the systematic evaluation and control of nanomedicines (FDA, 2004; Gaspar, 2010; Gaspar et al., 2014; Sainz et al., 2015; European Medicines Agency, 2017).

Ann. Since its advent in the field of cancer, nanotechnology has provided researchers with expertise to explore new avenues for diagnosis, prevention, and treatment of the disease. In turn, a non-biocompatibility surface (NB) can activate the immune system by adsorption to proteins like opsonins, even if the particle belongs to the class I of the NCS (Figure 3). 147, 516. Biopharm. The pharmaceutical manufacturing of nanomaterials involves two different approaches: top down and bottom down. Nanomedicine is a large industry, with sales reaching 6.8 billion dollars in 2004, and ith over 200 companies and 38 products worldwide. QSAR models are based on the hypothesis that the toxicity of nanomaterials and their cellular fate in the body can be predicted by their characteristics, and different biological reactions are the result of physicochemical characteristics, such as size, shape, zeta potential, or surface charge, etc., gathered as a set of descriptors.
