Lipossomas: Estrategia biotecnologica para liberacao controlada e direcionamento intracelular de farmacos com efeito antimicobacteriano

This text highlights the state of research related with the application of liposomes in the control of drug delivery and drug target to intracellular bacterial diseases, such as the tuberculosis. Liposome have several pharmaceutical applications and this article is primarily focused on the potential of this agregate on drug encapsalation especially antimycobacterial compounds. Case studies in which liposomes have successfully been used to improve pharmacological drug effect are presented. Mechanisms involved in intracellular drug delivery, possibilities of application, research and development efforts to address these objectives are discussed.

Filmes de metal-hexacianoferrato: Uma ferramenta em química analítica

Chemically modified electrodes based on hexacyanometalate films are presented as a tool in analytical chemistry. Use of amperometric sensors and/or biosensors based on the metal-hexacyanoferrate films is a tendency. This article reviews some applications of these films for analytical determination of both inorganic (e.g. As3+, S2O3 2-) and organic (e.g. cysteine, hydrazine, ascorbic acid, gluthatione, glucose, etc.) compounds.

Estudo de metodologia analítica para a determinação do cetoconazol em formulações farmacêuticas

Ketoconazole is a synthetic broad-spectrum oral and topical antifungal drug derived from imidazole, effective in the treatment of superficial mycoses and systemic infections. In this study we have tested several methods to analyze ketoconazole in various pharmaceutical products containing this drug, employing techniques such as UV and IR spectrophotometry and thermal analysis. The results showed that UV spectrophotometry is a fast, practical and economical method and indicated that other methods, such as IR spectrophotometry and thermal analysis, could be good alternative methods for ketoconazole analysis in certain pharmaceutical forms.
