Summary

Pharmacists are required to make certain kinds of calculations that determine the quantities of materials required for filling prescriptions and making up formulas. The new and expanded topics introduced in the fourth edition teach pharmacists and pharmacy students how to do the calculations required in current practice, covering important areas such as handling injectibles, including those used in parenteral nutrition and radiopharmaceuticals. The book also includes new chapters on isotonicity, intravenous fluids, and nutritional calculations. Features: * New concepts introduced in sequence, encouraging the student to master each concept before moving ahead * Many examples and practice problems, all with answers and the availability of rapid feedback build confidence * Filled with practical instruction relevant to the problems pharmacist face in their practice
