Formulations.
True
Which of the following is considered with Non-Sterile Preparation? A. USP 795 B. USP
797
A
Labels on Pharmacy-compounded products - Expiration Dates (Beyond Use Dates)
Water containing oral formulations
> The beyond use date is no later than 14 days when stored at controlled cold temperature
Water containing topical/dermal/mucosal liquid and semisolid formulations
> The beyond use date is no later than 30 days
Nonaqueous formulations
> The beyond use date is no later than the time remaining until the earliest expiration date of
any API (use no later than 25% of time of this api) or 6 months, whichever is earlier
T or F. For capsules, the label must include mcg or mg/capsule?
True - Does not require for tablet
T or F. You can rinse compounding equipment with tap water?
False - you can only rinse Purified water for rinsing equipment
,What is the best certified sterile compounding environment for injectable product?
Which ISO?
ISO class 5 (class 100) laminar air flow hood within ISO class 7 (class 10,000) clean
room with positive air pressure differential relative to adjacent areas.
ISO class 5 (class 100) clean room with positive air pressure differential relative to adjacent
areas or a barrier isolator that provides a ISO class 5 (class 100) environment for
compounding
T or F. Liquids in a container curve up, therefore measure at the top of the meniscus.
False. Must measure at the bottom of meniscus
What is the difference between glass and Wedge-wood/Porcelain(ceramic) Mortar and
Pestle?
wedge-wood or porcelain is used commonly and is best for reducing particle size of dry
powders and crystals
Glass is used for liquids or chemical that are oily or that will stain to the porcelain
T or F. It is safe not to use ointment paper to prepare creams and lotions because these
two formulation have the highest content of water. Water content will cause the paper
to moisten, and possibly tear.
True. we can use Glassine weighing paper

dispersions)?
A. Glycerin B. Mineral oil C. Castor oil D. Cottonseed oil E. Tween 80
A. Glycerin
> Rest are good levigating agents used to prepare oleaginous systems (W/O)
, > Additional agents used as levigating agents to prepare aqueous systems consist of
Propylene glycol, polyethylene glycol 80
Sometimes heat is used to mix things easier, but it lead to over-heating which produce
undesired chemical-reactions. What is the best way to prevent over-heating?
