[PDF Free Download] Pharmaceutical Calculations 13th Edition

This post contains Pharmaceutical calculations 13th edition Pdf free with the direct download link The use of calculations in pharmacy is varied and broad-based.  This E-book Pharmaceutical Calculations 13th Edition is written by Howard C. Ansel. It encompasses calculations performed by pharmacists in traditional as well as in specialized practice settings and within operational and research areas in the industry, academia, and government. In the broad context, the scope of pharmaceutical calculations includes computations related to:

chemical and physical properties of drug substances and pharmaceutical ingredients;
• biological activity and rates of drug absorption, bodily distribution, metabolism, and excretion
(pharmacokinetics)
• statistical data from basic research and clinical drug studies.
• pharmaceutical product development and formulation.
• prescriptions and medication orders including drug dosage, dosage regimens, and patient
compliance.
• pharmacoeconomics; and other areas.

For each of these areas, there is a unique body of knowledge. Some areas are foundational whereas others are more specialized, constituting a distinct field of study. This textbook is foundational, providing the basic underpinnings of calculations applicable to pharmacy practice in the community, institutional, and industrial settings.

In community pharmacies, pharmacists receive, fill, and dispense prescriptions, and provide relevant drug information to ensure their safe and effective use. Prescriptions may call for prefabricated pharmaceutical products manufactured in industry, or, they may call for individual components to be weighed or measured by the pharmacist and compounded into a finished product. In hospitals and other institutional settings, medication orders are entered on patients’ charts. Prescriptions and medication orders may be handwritten by authorized health professionals or transmitted electronically.

Preface:

The thirteenth edition of Pharmaceutical Calculations represents a thorough update of this textbook, which for more than six decades has met the needs of students in this important subject area. One of the most apparent changes in this edition is the inclusion of learning objectives for each chapter. The intent is not only to define the purpose and direct the student’s focus but also to provide a basis for self-assessment following completion. Another important addition, appearing in the Introduction, presents a step-wise approach in solving calculations problems that should prove beneficial to students toward understanding and building confidence. ( Pharmaceuticals book by Howard C. Ansel)


Throughout its history, one of the distinguishing characteristics of this textbook has been the inclusion of relevant background information to explain the pharmaceutical and/or clinical purpose underpinning each type of calculation. This practice has been continued, with new content in such areas as e-prescriptions; medication orders in nursing homes; hospice-care; patient self-administration of analgesia; intravenous infusion rate calculations for the critical care patient; patient conversions to alternative treatment plans; and other new and expanded areas.


Another traditional feature of this textbook has been the substantial use of examples and practice problems. New problems have been added to reflect current drugs in use, including products of biotechnology. For the first time, several problems are presented in multiple-choice format to reflect the method of testing used in some academic programs and employed on standardized examinations.
Several features that were introduced in the previous edition have been expanded, namely ‘‘Special Considerations,’’ used to point out the specific relevance of a type of calculation to a pharmaceutics or clinical application; ‘‘Calculations Capsules,’’ which present boxed summaries of the principle calculations in a chapter; and, ‘‘Case in Point,’’ which present practical case studies requiring pharmaceutical calculations.


The author acknowledges the difficulty in arranging the sequence of chapters to suit the order used within each academic program. However, an attempt has been made to present a logical approach by placing the fundamentals of pharmaceutical calculations in the initial chapters, followed by chapters having a clinical- or patient-care context, then chapters that address formulation and compounding calculations, and, finally, chapters described by some reviewers as meeting a ‘‘special interest.’’


The concluding section of review problems contains all of the types of problems presented in the chapters and may be used both for review and for competency assessment. A new set of problems titled ‘‘Physicians’ Medication Orders’’ is introduced. Appendices include the common systems of measurement and intersystem conversion, select graphical methods, and a glossary of pharmaceutical dosage forms and associated routes of administration.

Common & Decimal Fractions:

Common fractions are portions of a whole, expressed at 1 ⁄ 3, 7 ⁄ 8, and so forth. They are used only rarely in pharmacy calculations nowadays. It is recalled, that when adding or subtracting fractions, the use of a common denominator is required. The process of multiplying and dividing with fractions is recalled by the following examples.

Many other symbols (either letters or signs) are used in pharmacy, as in the metric and apothecaries’ systems of weights and measures, in statistics, in pharmacokinetics, in prescription writing, in physical pharmacy, and in other areas. Many of these symbols are included and defined elsewhere in this text
