  • Simultaneous Determination of Amoxicillin and Clavulanic Acid in Pharmaceutical Preparations by Capillary Zone Electrophoresis
    Brazilian Journal of Pharmaceutical Sciences vol. 52, n. 2, apr./jun., 2016 Article http://dx.doi.org/10.1590/S1984-82502016000200006 Simultaneous determination of amoxicillin and clavulanic acid in pharmaceutical preparations by capillary zone electrophoresis Gabriel Hancu1,*, Anamaria Neacşu1, Lajos Attila Papp1, Adriana Ciurba2 1Department of Pharmaceutical Chemistry, Faculty of Pharmacy, University of Medicine and Pharmacy, TîrguMureş, Romania, 2Department of PharmaceuticalTechnology, Faculty of Pharmacy, University of Medicine and Pharmacy, Tîrgu Mureş, Romania Clavulanic acid enhances the antibacterial spectrum of amoxicillin by rendering most β-lactamase producing isolates susceptible to the drug. A fast, simple and efficient capillary electrophoresis method was developed for the simultaneous determination of amoxicillin and clavulanic acid from complex mixtures. Using a 25 mM sodium tetraborate as background electrolyte at a pH of 9.30, + 25 kV applied voltage, 25 °C system temperature, UV determination at 230 nm; we succeeded in simultaneous separation of amoxicillin and clavulanic acid in approximately 2 minutes. The analytical performance of the method was evaluated in terms of reproducibility, precision, accuracy, and linearity. The optimized analytical method was applied for the determination of the two analytes from combined commercial pharmaceutical preparations. This CE method is fast, inexpensive, efficient, and environmentally friendly when compared with the more frequently used high performance liquid chromatography methods described in the literature. Uniterms: Amoxicillin/determination. Clavulanic acid/determination. Capillary electrophoresis/ quantitative analysis. Antibacterials/quantitative analysis. O ácido clavulânico acentua o espectro antibacteriano de amoxicilina, tornando a maioria dos isolados produtores de β-lactamase sensíveis ao fármaco. Desenvolveu-se um método rápido, simples e eficiente de electroforese capilar (EC) para a determinação simultânea de amoxicilina e de ácido clavulânico a partir de misturas complexas.

  • B-Lactams: Chemical Structure, Mode of Action and Mechanisms of Resistance
    b-Lactams: chemical structure, mode of action and mechanisms of resistance Ru´ben Fernandes, Paula Amador and Cristina Prudeˆncio This synopsis summarizes the key chemical and bacteriological characteristics of b-lactams, penicillins, cephalosporins, carbanpenems, monobactams and others. Particular notice is given to first-generation to fifth-generation cephalosporins. This review also summarizes the main resistance mechanism to antibiotics, focusing particular attention to those conferring resistance to broad-spectrum cephalosporins by means of production of emerging cephalosporinases (extended-spectrum b-lactamases and AmpC b-lactamases), target alteration (penicillin-binding proteins from methicillin-resistant Staphylococcus aureus) and membrane transporters that pump b-lactams out of the bacterial cell. Keywords: b-lactams, chemical structure, mechanisms of resistance, mode of action Historical perspective Alexander Fleming first noticed the antibacterial nature of penicillin in 1928. When working with Antimicrobials must be understood as any kind of agent another bacteriological problem, Fleming observed with inhibitory or killing properties to a microorganism. a contaminated culture of Staphylococcus aureus with Antibiotic is a more restrictive term, which implies the the mold Penicillium notatum. Fleming remarkably saw natural source of the antimicrobial agent. Similarly, under- the potential of this unfortunate event. He dis- lying the term chemotherapeutic is the artificial origin of continued the work that he was dealing with and was an antimicrobial agent by chemical synthesis [1]. Initially, able to describe the compound around the mold antibiotics were considered as small molecular weight and isolates it. He named it penicillin and published organic molecules or metabolites used in response of his findings along with some applications of penicillin some microorganisms against others that inhabit the same [4].

  • Who Expert Committee on Specifications for Pharmaceutical Preparations
    WHO Technical Report Series 902 WHO EXPERT COMMITTEE ON SPECIFICATIONS FOR PHARMACEUTICAL PREPARATIONS A Thirty-sixth Report aA World Health Organization Geneva i WEC Cover1 1 1/31/02, 6:35 PM The World Health Organization was established in 1948 as a specialized agency of the United Nations serving as the directing and coordinating authority for international health matters and public health. One of WHO’s constitutional functions is to provide objective and reliable information and advice in the field of human health, a responsibility that it fulfils in part through its extensive programme of publications. The Organization seeks through its publications to support national health strat- egies and address the most pressing public health concerns of populations around the world. To respond to the needs of Member States at all levels of development, WHO publishes practical manuals, handbooks and training material for specific categories of health workers; internationally applicable guidelines and standards; reviews and analyses of health policies, programmes and research; and state-of-the-art consensus reports that offer technical advice and recommen- dations for decision-makers. These books are closely tied to the Organization’s priority activities, encompassing disease prevention and control, the development of equitable health systems based on primary health care, and health promotion for individuals and communities. Progress towards better health for all also demands the global dissemination and exchange of information that draws on the knowledge and experience of all WHO’s Member countries and the collaboration of world leaders in public health and the biomedical sciences. To ensure the widest possible availability of authoritative information and guidance on health matters, WHO secures the broad international distribution of its publica- tions and encourages their translation and adaptation.

Danish copyright law restricts all other use without written permission of the publisher. Exception is granted for short excerpts for review purposes. iv Foreword The first edition of the Antibiotic Use Guidelines for Companion Animal Practice was published in autumn of 2012. The aim of the guidelines was to prevent increased antibiotic resistance. A questionnaire circulated to Danish veterinarians in 2015 (Jessen et al., DVT 10, 2016) indicated that the guidelines were well received, and particularly that active users had followed the recommendations. Despite a positive reception and the results of this survey, the actual quantity of antibiotics used is probably a better indicator of the effect of the first guidelines. Chapter two of these updated guidelines therefore details the pattern of developments in antibiotic use, as reported in DANMAP 2016 (www.danmap.org).

Abstract: Nitric oxide (NO) is a short-lived, ubiquitous signaling molecule that affects numerous critical functions in the body. There are markedly conflicting findings in the literature regarding the bimodal effects of NO in carcinogenesis and tumor progression, which has important consequences for treatment. Several preclinical and clinical studies have suggested that both pro- and antitumori- Citation: Mintz, J.; Vedenko, A.; genic effects of NO depend on multiple aspects, including, but not limited to, tissue of generation, the Rosete, O.; Shah, K.; Goldstein, G.; level of production, the oxidative/reductive (redox) environment in which this radical is generated, Hare, J.M; Ramasamy, R.; Arora, H.
