The most common compounding you arelikely to do is preparation of intravenous (IV) solutions. This compounding is fairly straightforward and will involveprimarily proportional Calculations . There will be times when you will need to determine the osmolarity of an IVsolution. Finally, you may need to change the concentration of an already-mixed IV solution, so you will need toknow how to dilute or concentrate that will likely also compound medications for topical application or administration via some body orifice. Thereare Calculations you will need to perform to ensure that ingredients are properly weighed and that solutions formucous membranes are isotonic, so they do not harm tissues.
Proportional Calculations You will use proportional calculations a lot in pharmacy, especially in the IV room. This is great, because you already know how to do these types of calculations. Proportional calculations involve using an available drug concentration and a desired final drug amount (in either weight or volume) to determine the amount ...
