Considering the potentialities of the use of thermal methods in the characterization, evaluation of thermal stability and drug degradation mechanisms, this project has as main objective to contribute with the development of such studies.The thermal methods can provide important information about stability, durability and physicochemical parameters of storage of drugs and their formulations as well as informations on the mechanisms and waste decomposition. Chromatographic procedures will be used in the separation and characterization of the solid wastes, while FTIR coupled to TG will be used in the volatiles characterization.We should consider also that the drugs are becoming important environmental contamination agents, for domestic and industrial effluents, which requires understanding of their mechanisms of decomposition, including the volatile and waste degradation at different temperatures. Thermal decomposition studies can guide in the alternative proposition for remediation processes, in the case of environmental contamination by drugs and their formulations, as well as in the elimination of material with validity expired or problematic lots.So, it is believed that the project must present embracing results in different fronts of research in the thermal analysis. Preliminary results obtained and presented in the literature and in scientific congresses, point to high possibility of success in the realization of the proposal and in the fulfillment of its objectives and demonstrate the capacity of the proponent group to conduct such studies.
