Alianças estratégicas e suas implicações para a configuração de capacidades tecnológicas: evidências da indústria farmacêutica multinacional

Esta dissertação examina as capacidades tecnológicas (sistema técnico-organizacional, molécula e medicamento) disponibilizadas em alianças estratégicas pela indústria farmacêutica multinacional, assim como as principais implicações das alianças estratégicas para a indústria farmacêutica em termos de configuração de suas capacidades tecnológicas . Essas questões são examinadas à base de evidências empíricas secundárias sobre alianças estratégicas em uma amostra de 25 companhias multinacionais da indústria farmacêutica, pertencentes a três grupos: companhia farmacêutica de grande porte (big pharma); companhia biofarmacêutica de grande porte (biofarma) e companhia pequena de pesquisa . A literatura relacionada oferece uma grande quantidade de estudos sobre alianças estratégicas e capacidades tecnológicas na indústria farmacêutica multinacional. Porém, o tema das implicações de tais alianças estratégicas para mudanças na configuração de capacidades tecnológicas ainda carece de mais fundamentação empírica, pela perspectiva de gestão de empresa e, mais precisamente, pela perspectiva de estratégia empresarial baseada em competências dinâmicas. Essa dissertação baseia-se em extensiva e sistemática coleta de evidências empíricas relativas às alianças estratégicas implementadas por 25 companhias da indústria farmacêutica e, publicadas durante o período de 1993 a 2003. Tais evidências empíricas foram coletadas a partir de três bancos de dados: Business & Industry; Galé e Dialog . Com relação aos resultados, foi encontrado que: Em termos de participações com capacidades tecnológicas ingressantes em alianças estratégicas: (i) as 'big pharmas' ingressaram com 11 % das 169 capacidades tecnológicas; (ii) as biofarmas ingressaram com 44% das 143 capacidades tecnológicas; (iii) as companhias pequenas de pesquisa ingressaram com 72% das 95 capacidades tecnológicas . 2 Em termos de implicações das alianças estratégicas para a mudança na configuração de capacidades tecnológicas que ingressaram em alianças estratégicas, foi encontrado que: (i) as 'big pharmas' aumentaram a proporção em moléculas (16% para 55%); (ii) as biofarmas aumentaram a participação em moléculas (22% para 32%) e sistema técnico-organizacional para pesquisa de molécula (49% para 55%); (iii) as companhias pequenas de pesquisa inseriram-se a uma nova atividade (comercialização de medicamento no mercado farmacêutico) a partir do aumento da participação em medicamentos (3% para 29%). Adicionalmente, atualizaram sistemas técnico-organizacionais para pesquisa de molécula . As evidências sugerem que o critério de escolha por companhia parceira e por mecanismo de aliança estratégica foi condicionado aos objetivos e às necessidades de cada grupo de companhia da indústria farmacêutica. Por fim, enquanto as companhias integradas, 'big pharmas' e biofarmas, principalmente, as primeiras, têm adaptado o modelo de negócio "Fully Integrated Pharmaceutical Company" com a adoção de alianças estratégicas para complementação de capacidades tecnológicas, as companhias pequenas de pesquisa capitalizam as suas capacidades tecnológicas através das alianças estratégicas e ingressam no mercado farmacêutico com a comercialização de medicamentos adquiridos por meio de alianças estratégicas. Portanto, as evidências sugerem que a busca por complementação de base de conhecimento para competir no mercado globalizado, tem implicado ainda que, informalmente, uma alteração na organização das atividades tecnológicas inovadoras, especialmente, em termos de produtos (medicamentos) .

Estudo da influência das competências dos níveis operacionais sobre os processos de estratégia: o caso da empresa farmacêutica MERCK S.A

Based on the approaches and studies on the subject of organizational strategies aimed at intra-firm aspects, resources and competencies developed by organizations have been identified as the key elements toward assessing and explaining a company¿s performance. Considering such perspective, it has been observed that the development and effective implementation of organizational strategies depend on the skills and knowledge supplied by workers who are motivated or led to contribute with their effort so as to meet the organization¿s goals. Considering this, the purpose of this dissertation is to identify how the competencies of the operational levels of an organization are mobilized to contribute to the shaping and implementation of organizational strategies. This assessment was accomplished by observing the existing relationships between organizational and human resources management processes and processes of short term and long term strategies in a company of the pharmaceutical industry. The analysis of the evidence collected during the observation of this company has shown a strong link between personnel processes and the accomplishment of short term strategic goals, and a weaker link with the establishment of long term strategies. As a rule, the corporation¿s operational levels have little influence on the strategic planning and its implementation, even though the company uses a model of competencies designed to create more effective and measurable relationships between individual competencies and the company¿s performance.

Pharmaceutical patent bargains: the Brazilian experience

In the backdrop of the strict patent regime flatly adopted by the World Trade Organization (WTO) for all countries, a few countries constantly challenge this system through aggressive patent bargains. Within the pharmaceutical sector, noticeably, some countries now threaten to issue or otherwise actually issue compulsory licenses that may sway large pharmaceutical companies into selling drugs with large discounts or into granting voluntary licenses domestically. That is conspicuously the negotiation strategy adopted by Brazil in its negotiations with big international pharmaceutical companies.This paper explains Brazil’s aggressive bargaining approach based on an analysis of two aspects of its political economy. The first has to do with the international context of patent bargaining in the post-WTO era. Accordingly, the existence of large and fast growing domestic markets position countries such as Brazil as strategic destinations for Foreign Direct Investment (FDI) and trade. Together with an absence of a propensity to innovate in pharmaceutical products, these conditions boost Brazil’s bargaining power for issuing compulsory licenses over pharmaceutical products. The second aspect is related to political economy dynamics inside Brazil. Accordingly, the political framework in Brazil undermines long-term policies and favors short-sighted ones also vis-a-vis R&D investments in the pharmaceutical industry. This remains true regardless of the strictness of the patent regime in place. The lesson of Brazil is relevant arguably for other more powerful developing countries which presently examine Brazil's approach while further challenging the WTO's strict patent policy for the future.

Avaliação da publicidade de medicamentos veiculada nas principais emissoras de rádio de Natal-RN

Drugs advertising is one of the most important marketing resources used by the pharmaceutical industry to induce people to buy these products although they do not have the real necessity to use them. The purpose of this article is to evaluate drugs advertisings transmitted on radio stations in Natal/RN, from October 2007 to September 2008. Were collected 228 advertising pieces, where, 21 were different among themselves and corresponded to 15 drugs. The results showed that 73,3% of the drugs ads were announced on AM station and 26,7% on FM station. The majority of the drugs were constituted of analgesics (26%), following by antiacids, vitamins, phitotherapics (13% each). The legal analysis showed that each advertising had some kind of infraction. The omission of the registration number happened in each advertising, following by the totally lack of contraindications (95,2%) and contraindications DCB/DCI (76,2%). In 42,9% advertisements were observed the relation between drugs use and physique/intellectual/emotional/sexual performance and/or beauty and 33% of them had abusive exploration of illnesses. The obligatory warning was omitted in 28,6% and the offer of financial bonus happened in 9,5% cases. The content analysis demonstrated that the most persuasion and convincing elements observed were indicatives of consumption appeal (34,2%). The study indicates the necessity of the topic drugs advertisements to be treated in a wide context, that is, to be discussed as a public health concern. Although the advertising regulation and inspection is the State responsibility , this should be shared with the advertising agency, pharmaceutical industry and media. Furthermore, it is indispensable to inform and to conscience the population of their rights in such mistaken situation

Evaluation of yeast cell wall on the performance of broiles fed diets with or without mycotoxins

This experiment aimed at evaluating the effects of the interactions between aflatoxin (500 or 250 ppb) and ochratoxin (500 or 250 ppb), and the possible benefits of adding yeast cell wall to prevent the effects of these mycotoxins in broiler chickens. Relative organ weight gain and live performance were evaluated at 21 and 42 days of age. Results indicated that at the levels of mycotoxins included in the experimental diets, ochratoxin reduced feed intake and body weight gain, and aflatoxin only affect feed intake of 21-day-old birds. No interaction was observed between aflatoxin and ochratoxin at the levels used in experimental study. Yeast cell wall did not significantly reduced the deleterious effects of ochratoxins. No significant differences were observed in relative organ weight gain. Yeast cell wall improved feed conversion ratio when birds were fed either contaminated or non-contaminated feeds.

Utilização de indicadores financeiros e não-financeiros na gestão de hotéis no Rio Grande do Norte: um estudo sob a ótica do Balanced Scorecard

This study presents the results of a research on the use of financial and non-financial performance indicators used by medium and large hotels. The research was conducted in Rio Grande do Norte, a Brazilian State. The objective is to identify the usage of performance measures by these companies. Hotel industry is one of the most important sectors in the Rio Grande do Norte economy. The research takes the Balanced Scorecard as a conceptual framework, since it represents an original contribution to the literature of managerial accounting, for rethinking old issues, pointing out themes that were forgotten or badly interpreted, to discuss the requirements imposed by the economy environment, dominated by competitive companies, and increasing the understanding of the relationship between strategy and operation. The objective of the research is to investigate if the hotel managers make use of a managerial information system or not, when evaluating the performance of their business unit. The research reveals the usage of performance evaluation using a large variety of measures. Among them is worth mention: the usage of accounting profit altogether with the EVA/MVA, the process cycle time, total quality management, process transformation, strategic mission, vision, strategic measures, measures related to feedback, risk, costs, productivity, incomes, customers retention, customer satisfaction and profitability, measures using time as a component, quality of the process, cost of the processes, employees capabilities, information systems, motivation, empowerment and alignment. The research leads to the conclusion that the usage of the deriving concepts of Balanced Scorecard can improve the performance measurement systems used by hotels

Ampolas de Vidro: Riscos e Benefícios

Background and objectives: Glass ampoules have been widely used in packaging injection drugs. Glass has important characteristics that allow it to be widely used in fabrication of recipients for drugs and other sterile substances. However, contamination of solutions with glass microparticles on breaking open glass ampoules, the presence of metals, percutaneous injury, and biological contamination justify the need of educational materials to orient the manipulation of ampoules. Contents: Glass microparticles generated in the snap-opening of ampoules, as well as metals that contaminate their contents can be aspirated and injected through several routes. Exogenous contaminations by glass and metals can reach several sites in the organism. They trigger organic reactions that may give rise to injuries. Opening ampoules can expose professionals to the risk of percutaneous injuries. These lesions increase the biological risk as they are the gateway for viruses and bacteria. Ampoules opening systems (VIBRAC and OPC) have been developed to reduce the incidence of such accidents. Alternative materials to glass may represent an interesting strategy to increase safety. The use of prefilled syringes may represent an evolution regarding safety. Conclusions: Team training and information provided by the pharmaceutical industry on the use of ampoules are fundamental in the prophylaxis of accidents and contaminations. The search for safer materials to replace glass is also important. © 2011 Elsevier Editora Ltda.

On the application of nanostructured electrodes prepared by Ti/TiO2/WO3 template : A case study of removing toxicity of indigo using visible irradiation

New assays with HepG2 cells indicate that Indigo Carmine (IC), a dye that is widely used as additive in many food and pharmaceutical industries exhibited cytotoxic effects. This work describes the development of a bicomponent nanostructured Ti/TiO2/WO3 electrode prepared by template method and investigates its efficiency in a photoelectrocatalytic method by using visible light irradiation and applied potential of 1V. After 2h of treatment there are reduction of 97% discoloration, 62% of mineralization and formation of three byproducts assigned as: 2-amine-5-sulfo-benzoic acid, 2,3-dioxo-14-indole-5-sulfonic acid, and 2-amino-α-oxo-5-sulfo-benzeneacetic acid were identified by HPLC-MS/MS. But, cytotoxicity was completely removed after 120min of treatment. © 2013 Elsevier Ltd.

Desenvolvimento de métodos analíticos qualitativos para a análise de darunavir comprimidos

Darunavir is a protease inhibitor used in the treatment of HIV infection. It is a pillar of the drug cocktail for patients diagnosed with the virus. Quality control in the pharmaceutical industry, to verify the content of active substance and study the physicochemical characteristics of the drug, is essential to ensure final product quality. Until now, standardized methods for the analysis of darunavir have not been available in official compendia. This justifies new research, to develop and validate analytical methods, as well as physicochemical and pharmaceutical analysis for this drug, both as a raw material and a finished product. Thus, in this study, (a) the average weight of darunavir tablets and (b) the melting point of the pure drug were determined, and the following analytical techniques were performed: (c) thin-layer chromatography, (d) ultraviolet spectroscopy, (e) infrared spectroscopy and (f) high performance liquid chromatography. By developing the above techniques, it is possible to make a qualitative assessment of the quality of darunavir tablets.

Caracterização físico-química e avaliação toxicológica preliminar do copolímero sulfato de condroitina-co-N-isopropilacrilamida para uso farmacêutico

A Indústria Farmacêutica utiliza polímeros em forma de nanopartículas em formulações de liberação controlada e vetorizada por possuírem baixo custo em relação a demais métodos de preparações de formas farmacêuticas, aparentemente não serem reconhecidos pelo sistema de defesa do organismo, proporcionar melhora da eficácia, diminuição da toxicidade e da dose de fármaco administrado. O sulfato de condroitina-co-Nisopropilacrilamida (SCM + NIPAAm) é um copolímero proposto para este fim, a partir da reação de um polímero sintético, o poli N-isopropilacrilamida (PNIPAAm), com características termossensíveis, com um natural, o Sulfato de Condroitina (SC), com características bioadesivas. Assim, a copolimerização pode ser capaz de somar estas propriedades e aperfeiçoar o seu uso como um veículo para liberação controlada. Este trabalho objetivou, portanto, realizar a caracterização fisico-quimica das partículas de sulfato de condroitina e Nisopropilacrilamida e do copolímero SCM+NIPAAm (2,5 % e 5%) e do SCM+PNIPAAm 2,5% e uma avaliação toxicológica parcial de um destes copolímeros que apresentar as melhores propriedades de um eficiente carreador de fármacos, selecionado a partir dos ensaios de caracterização físico-química. Para determinar a estrutura química dos sistemas particulados e analisar os seus componentes químicos, foi realizada a Espectroscopia de Ressonância Magnética Nuclear (RMN) e Espectroscopia do Infravermelho com Transformada de Fourrier (FTIR); Para analisar a morfologia das partículas, foi usado a Microscopia Eletrônica de Varredura (MEV); A Termogravimetria/ Termogravimetria Derivada e Análise Térmica Diferencial (TG/DTG) foi usada para avaliar o comportamento térmico dos sistemas particulados, bem como auxiliar na análise de Cinética de Degradação (CD, método de Flynn-Wall-Ozawa); Foi ainda realizado a técnica de degradação in vitro e a determinação carga superficial e tamanho de partículas (análise do Potencial Zeta, PZ). Para avaliar a toxicidade, foi realizado o bioensaio em microcrustáceo Artemia salina (24 e 48 h), viabilidade celular (citotoxicidade) em células PC-12 (método do MTT) e também a toxicidade aguda oral em camundongos. As análises de RMN, FTIR e MEV demonstraram semelhança quanto ao aspecto estrutural e morfológico entre os copolímeros estudados. As análises de TG demonstraram que o SCM+NIPAAm 5% apresentou maior estabilidade térmica em relação aos demais copolímeros avaliados, uma vez que sua decomposição polimérica ocorre em temperaturas superiores, em torno de 233ºC. O DTA demonstrou valores de temperaturas concordantes com os eventos térmicos de decomposição apresentados pelas curvas das análises TG. Sua estabilidade foi confirmada através da CD e estudo de degradação in vitro, apresentando, respectivamente, Ea > 100 kJ mol^-1 e perda de 48% da sua massa inicial após três meses. Além disso, SCM+NIPAAm 5% apresentou diâmetro de partícula inferior a 200 nm e índice de polidispersão de 0,35, além do PZ > -30mV, caracteristicas de um promissor candidato a carreador de fármacos. Em relação às avaliações toxicológicas, o SCM+NIPAAm 5% não apresentou toxicidade no bioensaio de A. salina (CL₅₀ > 1000) e no modelo celular avaliado, dentro das concentrações e circunstâncias de exposição estudadas. O SCM+NIPAAm 5%, na dose oral de 2000 mg/kg, não apresentou nenhum sinal evidente de toxicidade em camundongos, o que foi corroborado pela ausência de alterações anatomo-histopatológicas. A copolimerização do Sulfato de Condroitina e N-isopropilacrilamida na concentração estudada, dada suas características físico-químicas e toxicológicas preliminares, apresenta propriedades que contribuem para a proposta de um sistema que constitui uma nova forma de liberação controlada, especialmente de fármacos.

Estratégias tecnológicas em transformação: um estudo da indústria farmacêutica brasileira

The aim of this research is to analyze the extension of changes in technological strategies of a group of Brazilian pharmaceutical companies, which we believe were induced by transformations in the institutional environment during the 1990s. Major institutional changes, such as the enacting of laws that recognized drug patents rights and fostered generic drugs market, have strengthened the market insertion and competitive position of these companies, what would enable an increase in research and development efforts in Brazil. In addition to the literature on technology strategy and drug industry, this study was based on interviews with six Brazilian pharmaceutical companies, all of which were ranked among the top national companies in the industry and have been considered in previous studies particularly active in the process of changing technological strategies. This research confirmed a significant intensification of technology efforts carried out by Brazilian drug companies. Nevertheless, the R&D intensity is still far below the global pattern and innovative impacts are slight.

Structure- and ligand-based drug design approaches for neglected tropical diseases

Drug discovery has moved toward more rational strategies based on our increasing understanding of the fundamental principles of protein-ligand interactions. Structure( SBDD) and ligand-based drug design (LBDD) approaches bring together the most powerful concepts in modern chemistry and biology, linking medicinal chemistry with structural biology. The definition and assessment of both chemical and biological space have revitalized the importance of exploring the intrinsic complementary nature of experimental and computational methods in drug design. Major challenges in this field include the identification of promising hits and the development of high-quality leads for further development into clinical candidates. It becomes particularly important in the case of neglected tropical diseases (NTDs) that affect disproportionately poor people living in rural and remote regions worldwide, and for which there is an insufficient number of new chemical entities being evaluated owing to the lack of innovation and R&D investment by the pharmaceutical industry. This perspective paper outlines the utility and applications of SBDD and LBDD approaches for the identification and design of new small-molecule agents for NTDs.

Biological and physicochemical stability of ceftazidime and aminophylline on glucose parenteral solution

Ceftazidime is a broad spectrum antibiotic administered mainly by the parenteral route, and it is especially effective against Pseudomonas aeruginosa. The period of time in which serum levels exceed the Minimum Inhibitory Concentration (MIC) is an important pharmacodynamic parameter for its efficacy. One of the forms to extend this period is to administer the antibiotic by continuous infusion, after prior dilution in a Parenteral Solution (PS). The present work assessed the stability of ceftazidime in 5% glucose PS for 24 hours, combined or not with aminophylline, through High Performance Liquid Chromatography (HPLC). The physicochemical evaluation was accompanied by in vitro antimicrobial activity compared MIC test in the 24-hour period. Escherichia coli and Pseudomonas aeruginosa were the microorganisms chosen for the MIC comparison. The HPLC analysis confirmed ceftazidime and aminophylline individual stability on PS, while the MIC values were slightly higher than the mean described in the literature. When both drugs were associated in the same PS, the ceftazidime concentration by HPLC decreased 25% after 24 hours. Not only did the MIC values show high loss of antibiotic activity within the same period, but also altered MIC values immediately after the preparation, which was not detected by HPLC. Our results indicate that this drug combination is not compatible, even if used right away, and that PS might not be the best vehicle for ceftazidime, emphasizing the importance of the MIC evaluation for drug interactions.
