Introduction to Pharmaceutical Calculations

This revised and expanded third edition, written by experienced pharmacy lecturers, has been updated to include a new chapter on calculations involving information retrieval, the latest changes to the BNF, and body surface area charts from the BNF for Children. Further topics include: * rational numbers * systems of units * concentrations, dilutions and formulations * calculation of doses * density, displacement volumes and displacement values * calculations involving molecular weights * parenteral solutions and isotonicity * accuracy of measurement Each chapter contains learning objectives, worked examples, and sample questions and answers. Together with its companion text Pharmaceutical Calculations Workbook, also published by Pharmaceutical Press, Introduction to Pharmaceutical Calculations is essential reading for pharmacy undergraduates and pre-registration pharmacists.
