Pharmacy Calculations 3
This eight-part eLearning program addresses weight-volume (w/v), weight-weight (w/w), and volume-volume (v/v) relationships using three calculation methods: the concentration-volume equation (C1V1 = C2V2), the ratio and proportion method, and the dimensional analysis method.
PHARMACY CALCULATIONS 3 – PERCENT WEIGHT-VOLUME, WEIGHT-WEIGHT, AND VOLUME-VOLUME RELATIONSHIPS
Pharmacy compounding often involves dissolving a solute (i.e., the active pharmaceutical ingredient) inside a solvent (i.e., the base) to prepare a final homogenous mixture, known as a solution. The appropriate use of concentration expressions, such as weight-volume (w/v), weight-weight (w/w), and volume-volume (v/v), is vital for determining accurate solute and solvent amounts for a prescribed pharmaceutical preparation.
This multiple-method approach will provide participants with the necessary framework for problem-solving and formulation verification in actual practice. Systematic instructions on how to use these calculation methods are provided through animations and interactive problem-solving exercises to optimize engagement and retention. Completion of this eLearning program will provide participants with the confidence to accurately apply these essential pharmaceutical calculations in their day-to-day compounding practice.
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. |
