Pharmacy Calculations

This course exposes students to the concepts and theories involved in pharmaceutical calculations in the creation of medications. The fundamentals of drug dosage calculations and conversions, concentrations and dilutions and the use of the alligation grid will be discussed. Calculations for flow rates, TPN, and other IV medications will be explored.


Course Learning Objectives

Upon successful completion of this course, the student should be able to:

  • Calculate drug dosages and solve one-step dosage calculations.
  • Determine dosages based on gram ratios and convert weights from pounds to kilograms.
  • Identify the calculations and preparations for specific concentrations and dilutions.
  • Define alligation and explain when to use the alligation principle for calculations.
  • Define flow rates and calculate flow rates to determine drops/minute and milliliters/hour.
  • Perform calculations for TPN (total parenteral nutrition) and IV medications, and explain the importance of electrolytes.
