Pharmacy Calculations 1- Unit Conversions, Rounding, Densities, Percentages, & Ratios
This activity largely focuses on USP General Chapter <1160> Pharmaceutical Calculations in Pharmacy Practice and provides the general information needed to perform the requisite calculations within a compounding pharmacy.
In this eLearning module, you will learn about the mathematics in compounding and calculations needed to establish formulations, modify existing formulations and verify the work before, during, and after a compounded medication is prepared. You will learn how to convert units of measure, apply accuracy guidelines, properly round calculations, calculate densities, recognize percent error, express relationships as percentages and ratios, utilize specific gravity calculations, and create stock solutions of a specific concentration.
|Upon successful completion of the eLearning module you will receive an LP3 Network certificate, which can be printed and displayed in your compounding pharmacy as evidence of your training.|
