La regulación de la Administración electrónica y sus principios rectores

[spa] Actualmente, nos encontramos inmersos en un proceso de globalización y tecnificación al que las Administraciones públicas, como parte integrante de l a sociedad, no pueden permanecer ajenas. Todas las Administraciones, en sus distintos niveles y ámbitos de actuación, han introducido en su actividad las nuevas tecnologías de la información y la comunicación, y han puesto en marcha un proceso transformación de carácter cultural, organizativo y jurídico que ha fructificado en un nuevo modelo de gestión de la actividad pública conocido bajo el nombre de Administración electrónica. El uso de las nuevas tecnologías y la transición de una Administración «en pa pel» a una Administración electrónica han conllevado una serie de reformas de nuestro ordenamiento jurídico: nuevas normas y reforma de otras ya existentes que regulan los aspectos técnicos derivados de la utilización de las nuevas tecnologías por parte de la Administración, así como los derechos y garantías de los que están revestidos los ciudadanos cuando se relacionan con la Administración por medios telemáticos. Con este telón de fondo, podemos definir un elenco de principios que regirán la actuación de la Administración electrónica y en los que se erigen como protagonistas aquellos que persiguen garantizar la igualdad y la no discriminación de los ciudadanos, combatiendo la denominada brecha digital.

La Administración electrónica en España: de la 'administración en papel' a la 'e-administración'

[spa] Desde principios de los noventa, nuestra sociedad está sufriendo una serie de cambios asociados al uso masivo de las nuevas tecnologías de la información y la comunicación (TIC). En este nuevo modelo social, conocido bajo el nombre de sociedad de la información, las Administraciones públicas han tenido que adaptarse, introduciendo las nuevas tecnologías en su actividad cotidiana. No obstante, la transformación de las Administraciones públicas va más allá del uso de las TIC, pues supone una auténtica transformación de una administración en papel a una verdadera administración electrónica. Todo ello conlleva modificaciones en el ordenamiento jurídico, así como en las relaciones entre la Administración con los ciudadanos. En este trabajo, analizamos el desarrollo de este proceso en las Administraciones públicas españolas.

Validação de métodos cromatográficos para a determinação de resíduos de medicamentos veterinários em alimentos

Different agencies that supply validation guidelines worldwide establish almost the same parameters to be evaluated in the validation process of bioanalytical methods. However, they recommend different procedures, as well as establish different acceptance criteria. The present review delineates and discusses the stages involved in the validation procedures of bioanalytical methods designed for determining veterinary residues in food, explaining the main differences in the guidelines established for this purpose by the main regulatory agencies in the world.

Nivel de calidad de los medicamentos elaborados por los alumnos en el laboratorio de prácticas y de su control como producto acabado por parte de los mismos alumnos

Una de las prácticas de laboratorio de Tecnología Farmacéutica requiere la elaboración de comprimidos en la asignatura de Farmacia Galénica II siguiendo el mismo flujo de fabricación al empleado en la industria farmacéutica (pesada, tamización, mezclado, amasado, granulación, secado, mezclado y compresión). Estos comprimidos se analizan en la asignatura de Farmacia Galénica III (entre 6 y 12 meses más tarde) por los mismos alumnos según las directrices de la Real Farmacopea Española.En el trabajo se exponen gráficamente los resultados hallados y se comentan los principales puntos de mejora ya que el producto elaborado no es conforme en la mayoría de los casos (sólo alrededor del 50% de los productos elaborados por los alumnos podrían ser conformes, aún siendo un proceso validado). Realmente, la experiencia de los operadores es el punto más crítico que influye en los resultados de estos lotes de comprimidos, sobre todo en el laboratorio analítico. Esta hipótesis ha sido confirmada en lotes analizados por el personal cualificado del departamento de control de calidad del Servei de Desenvolupament del Medicament de la Facultat de Farmàcia de la Universitat de Barcelona, ya que en todos los casos los resultados obtenidos fueron más exactos, repetitivos y cercanos a los teóricos.

O papel governamental como ator essencial para a P&D de medicamentos: um estudo de casos

The importance of natural products as a source of new high value-added drugs has, no doubt, transformed Brazilian megadiversity into one of the country's most valuable and strategic assets. Thus the rational exploration of the Brazilian flora on an economic basis should be considered as part of a national development strategy. In this respect, governmental mechanisms to stimulate regulation on the access, bioprospection and industrial use of natural products represent a crucial issue. The aim of this paper is to show how the incentives and institutional arrangements that led to one of the greatest breakthroughs in the pharmaceutical industry, the development and commercialization of the anti-cancer agent Taxol, could be applied to the Brazilian case.

Determinação espectrofotométrica de hexametilenotetramina (HMT) em medicamentos, utilizando ácido cromotrópico e forno de micro-ondas

This paper proposes a methodology for spectrophotometric determination of hexamethylenetetramine (HMT) by using chromotropic acid in a phosphoric acid media employing a domestic microwave oven as a source of heating. The reddish-purple soluble product is quantitatively formed after 30 s of irradiation and obeys the Beer´s law in the range between 0.1-1.2 mg L-1 HMT (r = 0.99925). The method was applied successfully in commercial pharmaceutical preparations containing dyes in their composition. The results showed that the method proposed is feasible for simplicity, speed, low cost, precision and accuracy when compared with United States Pharmacopeia official method.

Avaliação do perfil de dissolução de medicamentos utilizando-se espectroscopia eletrônica multivariada

In this work the evaluation of the dissolution profile of captopril-hydrochlorothiazide and zidovudine-lamivudine associations were carried out by multivariate spectroscopic method. The models were developed by partial least square regression from 20 synthetic mixtures using mean-centered spectral data. The external validation was accomplished with 5 synthetic mixtures shown mean prevision error of about 1%. Good agreement was observed in the analyses of commercial drugs (content uniformity and dissolution profile), considering the results obtained by the standard chromatographic method, with prevision error lower than 10%.

Desenvolvimento e aplicação de métodos para a determinação de ivermectina em medicamentos de uso veterinário

Two methods for the determination of Ivermectin in veterinarian medications were developed and compared. One of the methods was based on UV spectrometry and the other on HPLC-UV. The former method was shown to be positively biased regarding the nominal concentrations of Ivermectin in different medications. The method of standard addition was unable to correct this bias, indicating significant matrix effects. The HPLC-UV method showed good linearity, throughput, recovery and limits of detection and quantitation adequate for its application in the evaluation of Ivermectin in medications. Several medications were evaluated and good agreement between our results and their nominal concentrations was found.

Internalização de farmoquímicos e medicamentos para doenças tropicais negligenciadas: proposta de interação entre Governo - Universidade - Empresa

History shows that public health actions to combat epidemics are most effective when there is constant synergy of both government and society, exemplified by prevention actions in the fight against dengue fever, H1N1 influenza etc. Private-public-partnerships (PPP) can also provide more dynamic and consistent results in production through interaction among Government, University and Enterprise actors. This article puts forward proposals to tackle the problem of neglected tropical diseases via the formation of a Management Council using Etzkowitz's Triple Helix concept to attenuate this public health issue in Brazil.

Avaliação de métodos de extração para a determinação de cromo e níquel em formulações farmacêuticas e em matérias-primas usadas na fabricação de medicamentos à base de cefalexina e ciprofloxacino

This paper reports the evaluation of extraction strategies for the treatment of medicine samples to determine chromium and nickel by GFAAS. Different approaches for extraction were evaluated and the most efficient involved magnetic stirring. The metals were quantitatively extracted by stirring 0.20 g samples with 25 mL of 2.0 mol L-1 HCl solution for 60 min. The developed method was successfully applied for the determination of Cr and Ni in tablets containing antibiotics and raw materials, with cephalexin and ciprofloxacin as active ingredients.

Influência de processos antagônicos no desenvolvimento de sistema de análises em fluxo para a determinação espectrofotométrica de propiltiouracil em medicamentos

A multi-commuted flow system was developed to determine propylthiouracil (PTU) based on the reaction of its thiol form with iminoquinone radical generated by the oxidation of N,N-dimethyl-p-phenylenediamine in an alkaline medium. PTU can be found in tautomeric forms and the tautomeric equilibrium was displaced to enhance the thiol form. However, the reaction product is unstable and its residence time in the flow path was carefully investigated. The proposed procedure showed good precision (< 1.5%) and a limit of detection (3s) of 0.11 mg L-1. High recoveries were obtained in the validation test. The procedure was employed for propylthiouracil determination in medications.

Desenvolvimento e validação do método QuEChERS na determinação de resíduos de medicamentos veterinários em leite e carne de búfalo

Analytical methods were developed and validated to determine residues of veterinary drugs in buffalo milk and meat, using the QuEChERS method and gas chromatography-mass spectrometry. Both milk and meat, at 2 g of sample, 4 mL of acetonitrile, 0.8 g of MgSO4 and 0.2 g of NaCl, were used in the liquid-liquid partition, whereas 50 mg of C18, 50 mg of PSA and 150 mg of MgSO4 were employed in the dispersive solid-phase extraction (d-SPE). The methods showed sensitivity, precision and accuracy. The quantitation limits were in agreement with the maximum residue limit established by the Codex Alimentarius, FAO and WHO.

O estado da arte na determinação de resíduos de medicamentos veterinários em alimentos de origem animal empregando técnicas cromatográficas acopladas à espectrometria de massas

The determination of veterinary drug residues in foods of animal origin is an important issue because of the risk these compounds pose to human health in addition to their persistence and tendency to bioaccumulate. In recent years, significant progress has been made in the area and this review presents the state of the art in sample preparation procedures associated with chromatographic techniques coupled to mass spectrometry for multiresidue determination of veterinary drugs in food of animal origin at concentration levels suitable for the control of residues and contaminants in food.

Impactos da nanotecnologia na saúde: produção de medicamentos

Several studies have described the benefits of nanoscience and nanotechnology (N&N) in different sectors such as agriculture, energy, environmental preservation, and public health. The rapid evolution of N&N can be shown through a panoramic analysis of scientific papers and patents. In the area of public health, it is estimated that the global market for nanotechnology products will expand to 160 billion U.S. dollars in 2015. The Brazilian government has also strengthened its innovative potential in N&N through economic subsidies, as observed for other countries. This review is focused on the current landscape of N&N in a therapeutic context, highlighting the development of nanotech-products produced with biocompatible and biodegradable materials that are already commercially available or under investigation. Most studies under investigation are focused on the development of nanotechnology-based formulations intended for treatment of cancer, inflammatory, cardiovascular, and neurological diseases. Although there are several advantages of N&N in healthcare, many challenges have to be conquered to increase the availability of nanotechnology products in toxicological, preclinical and clinical studies, scale-up, regulatory, and private investments.
