Introduction to Pharmaceutical Calculations

Errors in calculating drug dosages can cause significant harm to patients. As pharmacists are seen as a 'safety net' by fellow healthcare professionals, it is essential that pharmacy students fully understand how to calculate a correct dosage.

This revised and expanded 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.
