Publication Date: 2009-03-16
ISBN-10 / ASIN: 0853698406
ISBN-13 / EAN: 9780853698401

Product Description:

This book provides reliable, unbiased and evaluated information on drugs and medicines used throughout the world. Each new drug licensed for use has its own potential benefits and adverse effects, and its own profile for dosage, administration and indications. Furthermore, manufacturers make regular changes to existing drug names and formulations, which can affect their interactions and safe usage. Health professionals require the correct answers and need to have confidence in the drugs information they use – but with medicines evolving at this rate, how can they be sure their knowledge is up to date? "Martindale" contains up to date information about more than 5,800 substances. Each and every entry is reviewed by our pharmaceutical editors to ensure health professionals have the most current data. Formulations change. Definitions change. Names change. But you can always trust "Martindale".

NMR Spectroscopy in Pharmaceutical Analysis

NMR Spectroscopy in Pharmaceutical Analysis.
By Iwona Wawer, Bernd Diehl, Ulrike Holzgrabe

Publisher: Elsevier Science
Number Of Pages: 528
Publication Date: 2008-10-10
ISBN-10 / ASIN: 0444531734
ISBN-13 / EAN: 9780444531735
Binding: Hardcover

For almost a decade, quantitative NMR spectroscopy (qNMR) has been established as valuable tool in drug analysis. In all disciplines, i. e. , impurity profiling and assay, qNMR can be utilized.
Separation techniques such as high performance liquid chromatography, gas chromatography, super fluid chromatography and capillary electrophoresis techniques, govern the purity evaluation of drugs. However, these techniques are not always able to solve the analytical problems often resulting in insufficient methods. Nevertheless such methods find their way into international pharmacopoeias. Thus, the aim of the book is to describe the possibilities of qNMR in pharmaceutical analysis.
Beside the introduction to the physical fundamentals and techniques the principles of the application in drug analysis are described: quality evaluation of drugs, polymer characterization, natural products and corresponding reference compounds, metabolism, and solid phase NMR spectroscopy for the characterization drug substances, e.g. the water content, polymorphism, and drug formulations, e.g. tablets, powders. This part is accompanied by more special chapters dealing with representative examples. They give more detailed information by means of concrete examples.

combines theory, techniques, and concrete applicationsall of which closely resemble the laboratory experience
considers international pharmacopoeias, addressing the concern for licensing
features the work of academics and researchers, appealing to a broad readership.

Hardbound. In analytical chemistry and pharmaceutical technology attention is increasingly focussed on improving the quality of methods and products. This book aims at fostering the awareness of the potential of existing mathematical and statistical methods to improve this quality. It provides procedures and ideas on how to make a product or a method less sensitive to small variations in influencing factors. Major issues covered are robustness and stability improvement and ruggedness testing. General strategies and a theoretical introduction to these methods are described, and thorough overviews of methods used in both application areas and descriptions of practical applications are given.

Features of this book:

â ¢ Gives a good overview of mathematical and statistical methods used in two application areas, i.e. pharmaceuticaltechnology and analytical chemistry

â ¢ Illustrates the different approaches available to attain robustness.

Heterocyclic Chemistry.

Heterocyclic Chemistry.
By John A. Joule, Keith Mills

  • Publisher: Wiley-Blackwell
  • Number Of Pages: 640
  • Publication Date: 2010-06-15
  • ISBN-10 / ASIN: 1405133007
  • ISBN-13 / EAN: 9781405133005

Product Description:

This book has so closely matched the requirements of its readership over the years that it has become the first choice for chemists worldwide.

Heterocyclic chemistry comprises at least half of all organic chemistry research worldwide. In particular, the vast majority of organic work done in the pharmaceutical and agrochemical industries is heterocyclic chemistry.

The fifth edition of Heterocyclic Chemistry maintains the principal objective of earlier editions – to teach the fundamentals of heterocyclic reactivity and synthesis in a way that is understandable to second- and third-year undergraduate chemistry students. The inclusion of more advanced and current material also makes the book a valuable reference text for postgraduate taught courses, postgraduate researchers, and chemists at all levels working with heterocyclic compounds in industry.

Fully updated and expanded to reflect important 21st century advances, the fifth edition of this classic text includes the following innovations:

  • Extensive use of colour to highlight changes in structure and bonding during reactions
  • Entirely new chapters on organometallic heterocyclic chemistry, heterocyclic natural products, especially in biochemical processes, and heterocycles in medicine
  • New sections focusing on heterocyclic fluorine compounds, isotopically labeled heterocycles, and solid-phase chemistry, microwave heating and flow reactors in the heterocyclic context

Essential teaching material in the early chapters is followed by short chapters throughout the text which capture the essence of heterocyclic reactivity in concise resumés suitable as introductions or summaries, for example for examination preparation. Detailed, systematic discussions cover the reactivity and synthesis of all the important heterocyclic systems. Original references and references to reviews are given throughout the text, vital for postgraduate teaching and for research scientists. Problems, divided into straightforward revision exercises, and more challenging questions (with solutions available online), help the reader to understand and apply the principles of heterocyclic reactivity and synthesis.

Organic Mechanisms: Reactions, Stereochemistry and Synthesis

Organic Mechanisms: Reactions, Stereochemistry and Synthesis.
By Reinhard Bruckner

  • Publisher: Springer
  • Number Of Pages: 856
  • Publication Date: 2010-03-23
  • ISBN-10 / ASIN: 3642036503
  • ISBN-13 / EAN: 9783642036507

Product Description:

This English edition of a best-selling and award-winning German textbook Reaction Mechanisms: Organic Reactions · Stereochemistry · Modern Synthetic Methods is aimed at those who desire to learn organic chemistry through an approach that is facile to understand and easily committed to memory. Michael Harmata, Norman Rabjohn Distinguished Professor of Organic Chemistry (University of Missouri) surveyed the accuracy of the made certain contributions, and above all adapted its rationalizations to those prevalent in the organic chemistry community in the English-speaking world.

Throughout the book fundamental and advanced reaction mechanisms are presented with meticulous precision. The systematic use of red "pushing arrows" allows students to follow each transformation elementary step by elementary step. Mechanisms are not only presented in the traditional contexts of rate laws and substituent effects but, whenever possible, are illustrated using practical, useful and state-of-the-art reactions. The abundance of stereoselective reactions included in the treatise makes the reader familiar with key concepts of stereochemistry.

The fundamental topics of the book address the needs of upper-level undergraduate students, while its advanced sections are intended for graduate-level audiences. Accordingly, this book is an essential learning tool for students and a unique addition to the reference desk of practicing organic chemists, who as life-long learners desire to keep abreast of both fundamental and applied aspects of our science. In addition, it will well serve ambitious students in chemistry-related fields such as biochemistry, medicinal chemistry and pharmaceutical chemistry.
