Advanced Pharmacy Calculations

In this episode of TechPrep: Rapid PTCB Review, we review advanced pharmacy calculations with a focused, exam-relevant approach tailored to pharmacy technician practice and the PTCB exam. Building on foundational pharmacy math, this episode covers complex calculations used in retail and hospital settings, including insulin day supply, weight-based dosing, morphine milligram equivalents (MME), IV flow rates, product strength adjustments, and compounding calculations.

Accurate advanced calculations are essential for medication safety, prescription processing, appropriate insurance billing, and preparing medications correctly. You'll learn how to calculate days' supply for insulin and eye drops, determine medication quantities based on patient weight, understand opioid equivalencies, calculate IV infusion rates, and manipulate stock solutions to achieve a desired concentration. The episode also reviews dilution, allegation, and compounding math, with worked examples to reinforce the calculations and prepare you for the PTCB exam.

What You'll Learn

• How to calculate insulin and eye drop days' supply, including concentration differences, maximum daily doses, and required quantities

• How to solve weight-based dosing problems and calculate medication quantities for pediatric patients

• The fundamentals of morphine milligram equivalents (MME), opioid conversion ratios, and prescription monitoring programs

• How to calculate IV infusion flow rates and distinguish between dilution, concentration, and allegation

• How to adjust product strengths and perform compounding calculations using percentages, ratios, and stock solutions

Key Takeaways

• Accurate day supply calculations support appropriate prescription billing and help prevent refill issues.

• Understanding medication concentrations and weight-based dosing is essential for safe and accurate medication preparation.

• MME calculations help pharmacy technicians understand opioid equivalencies and the role of prescription monitoring programs, while state-specific requirements must also be considered.

• Dimensional analysis and a systematic approach to calculations help reduce errors when adjusting product strengths, preparing compounded medications, and calculating infusion rates.
