Toxicology Safety

In the last 30 years, the use of in vitro tools for toxicological studies and evaluation has become relevant and the number of scientific works and techniques has increased day by day. One of the most important advantages of in vitro systems is their ability to serve as model for the central events in the in vivo toxicological process, and a depth evaluation of the intrinsic cellular toxicity can provide useful information for toxicological safety evaluation.

Apart from the pure process-driven requirements of the disintegration within a defined time span and the proof of ultimate biodegradability, it is necessary to make sure that there is no negative impact of degradation products or intermediates of the degradation process on the environment. Adequate information has to be provided for a comprehensive assessment of environmental and toxicological safety.

It may require use of an organic solvent. For example, drug is often solubilized in pure cosolvent (e.g., ethanol, dimethylsulfoxide, dimethylacetamide, orN-methyl pyrrolidone) which is than added to the emulsion. As mentioned earlier, this bears toxicological/safety concerns. 

The most recently reported UK results on surveillance for veterinary drug residues in meat and animal products show that traces of these compounds can, and sometimes do, arise in food. As all of these compounds are biologically potent in order to be effective in use, it is necessary to ensure that any residual activity in a food product does not present a risk to the consumer. The use of veterinary medicines inevitably leads to the presence of trace residues in food and the purpose of toxicological safety evaluation is to determine at what concentration the residues of a particular compound becomes a cause for concern with regard to human health. Thus, dose-response relationships have to be established and used to determine the concentration of a dmg at which the risks to human health become acceptable and are outweighed by the benefits from the use of the drug. This is in essence the process involved in the setting of Acceptable Daily Intakes (ADIs) and... 

Dr. Meskin has been involved with both the local and national Institutes of Food Technologists (IFT) for more than 25 years. He is a past chair of the Southern California IFT and remains involved in the group. Dr. Meskin has been an active food science communicator for the national IFT, was a member of the IFT/National Academy of Sciences Liaison Committee, and has served as a member of the IFT Expert Panel on Food Safety and Nutrition. He is also involved in several IFT divisions, including the Nutrition, Toxicology Safety Evaluation Biotechnology Nutraceuti-cal and Functional Foods and Religious Ethnic Foods divisions. 

There is little doubt that intrepid entrepreneurs will continue to champion ideas for the application of ionic liquids. Without a doubt, further uses of these materials will be found and justified for commercial use. However, the perceived disadvantages, and particularly the toxicity issues, will temper enthusiasm until the data obtained provide reassurances that an ionic-liquid-based process satisfies all the economic, toxicological, safety, and (in the pharmaceutical industry) FDA regulatory criteria to justify implementation.

Leachables in orally inhaled and nasal drug products (OINDP) are compounds which are present in the drug product due to leaching from container closure system components. Extractables are compounds that can be extracted from OINDP device components, or surfaces of the OINDP container closure system when in presence of an appropriate solvent(s) and/or condition(s). Leachables are often a subset of, or are derived directly or indirectly from, extractables. Extractables may, therefore, be considered as potential leachables in OINDPs. Some leachables may affect product quality and/or present potential safety risks, therefore regulatory guidance has provided some recommendations regarding the analysis and toxicological safety assessment (i.e., qualification) of such compounds.

Industrial applications of nature-identical and artificial flavourings have to be based on two pillars a clear understanding of flavour-relevant molecules and at the same time the use of technically feasible, high-purity, high-yield syntheses. In addition, performance criteria like pH, oxidation and chemical stability as well as toxicological safety have to be considered.
