Security factors<\/span><\/h3>\n<p>&nbsp;<\/p>\n<p>Both annexe 3 of the ICH Q3C (R4) and annexe 3 of VICH GL 18 give some guidelines to fix the security factors (f1,f2,f3, f4 y f5).<\/p>\n<h3><span style=\"color: #00ccff;\">3. Requiring dedicated facilities<\/span><\/h3>\n<p>&nbsp;<\/p>\n<p>Those active substances and final product with a high potential sensitising degree for which the scientific data doesn&#8217;t endorse an acceptable exposition level for its use in a facility and that the facility can not adequately control with technical or organisational methods, will require dedicated installations. <strong>No products are detailed a priori. \u00a0<\/strong><\/p>\n<h3><span style=\"color: #00ccff;\">4. Proteines, macromolecules and peptides<\/span><\/h3>\n<p>&nbsp;<\/p>\n<p>It speaks\u00a0specifically about the macromolecules and peptides for which it is known that they degrade and denature when they are exposed to extreme pH or warm, they convert into inactive products, as they cause the deterioration and inactivation of products based on proteins. For this case it has no sense to apply the exposition risk methodology based on the PDE limits.<\/p>\n<h3><span style=\"color: #00ccff;\">5. Toxicological and medical expert<\/span><\/h3>\n<p>&nbsp;<\/p>\n<p><strong>The toxicological data and the toxicological expert are key for the definition of the starting values<\/strong>\u00a0for the calculation of the cleaning limits and the product harmonization risk analysis. The role of the expert is to realize an evaluation of the potential health adverse effects risk, after the exposition to the studied medicine. It is a sistematic scientific caracterisation to identify, describe and measure the risk after the revision of the relevant toxicological data available related to the studied product. For that purpose, it is necessary to validate the existing toxicological data and make a balance of the toxical effects found.<\/p>\n<h3><span style=\"color: #00ccff;\">6. Toxicological and medical revision<\/span><\/h3>\n<p>&nbsp;<\/p>\n<p>The toxicological revision will be done through the access and analysis of the information obtained in medical databases (Pubmed, scifinder\u2026), and specific toxicological database (TOXNET, specific pages of each country\u2026). In the final report and in the definition of the toxicological values, all the factors that define the international guides defining the toxicological values as the potential genotoxic and carcinogenic, security factors (that assure for example the extrapolation between the animal and human toxicology) via of administration (which among others can modulate the exposition related to the administration orally or topically, for example) bioavailability, tipology of the patients, are taken into account, appart from the bibliographic revision.<\/p>\n<p>&nbsp;<\/p>\n<p>As the guideline annexe shows,\u00a0<strong>the CV of the toxicologist has to be annexed and it is also recommended the CV of the medical expert in medicines evaluation.<\/strong><\/p>\n<h1><b><strong>3.
