EFEITO DE SURFACTANTES NA ESTABILIDADE DE COMPOSTOS DE USO TERAPEUTICO

A critical revision of literature as regards to the drug stability in the presence of surfactants were realized. The functional groups envolved in the drug decomposition were used to the development of the discussion. The analysis indicated that the detergent effect can be used to control the rates and mechanisms of drug decomposition and to obtain specific information about the drug reactivity in the environment of pharmacological action.

Farmacología en la tercera edad: Medicamentos de uso continuo y peligros de la interacción medicamentosa

Introduction: It was observed a considerable growth of elderly people. They are who use more medicines. The physiological changes associated with the age advancing can make pharmacokinetic and pharmacodynamic alterations. The cognitive decline, physical limitations and associate chronic pathology affect the medications appropriately use ability. Aims: Based in a literature review, appoint the main pharmacological groups prescribed to the elderly and the drug-drug interaction risks. Conclusion: The most of elderly use continually at least 3 medicines, the most prescribed are to cardiovascular and psychic diseases treatment.

Recent applications of analytical techniques for quantitative pharmaceutical analysis: A review

The intension of this paper was to review and discuss some of the current quantitative analytical procedures which are used for quality control of pharmaceutical products. The selected papers were organized according to the analytical technique employed. Several techniques like ultraviolet/visible spectrophotometry, fluorimetry, titrimetry, electroanalytical techniques, chromatographic methods (thin-layer chromatography, gas chromatography and high-performance liquid chromatography), capillary electrophoresis and vibrational spectroscopies are the main techniques that have been used for the quantitative analysis of pharmaceutical compounds. In conclusion, although simple techniques such as UV/VIS spectrophotometry and TLC are still extensively employed, HPLC is the most popular instrumental technique used for the analysis of pharmaceuticals. Besides, a review of recent works in the area of pharmaceutical analysis showed a trend in the application of techniques increasingly rapid such as ultra performance liquid chromatography and the use of sensitive and specific detectors as mass spectrometers.
