what types of medications must be prepared in a sterile manner?
ophthalmics, inhalations, irrigations, IVs
BUD in sterile compounding
lower the risk of contamination, longer the BUD
if refrigerated - BUD 14 days
ISO air quality in sterile compounding
the number of particles per volume of air of a specified particle size
the lower the count, the cleaner the air
What must the ISO be in the compounding area?
primary engineering control (PEC): at least 5 - 3,520 buffer area (area in room around PEC): at least 7 - 35,200 ante room if positive pressure into buffer area: 8 - 352,000 ante room if negative pressure into buffer area: 7 - 3,520,000
what do you clean the inside of PEC with?
sterile IPA 70%
sterile lint-free wipes
at least how many air changes per hour does the PEC in an buffer room have to be for a compounded sterile product to be made?
at least 30 air changes per hour
what kind of devices are PECs?
ventilation devices
the laminar airflow workbench is for what type of CSP?
non-hazardous
what is laminar airflow
smooth unidirectional airflow in parallel lines to prevent particles from hitting each other and landing on surfaces
what is the airflow direction of the laminar hood?
horizontal (back of hood to front)
vertical (above to down)
where should products not be placed in a vertical or horizontal hood.
horizontal: nothing should be behind
vertical: nothing should be above
compounding is done in the cleanest part of the hood, which is where?
~6 inches from the front of the hood
what are biological safety cabinets?
They are for hazardous or chemo drug compounding and are negative pressure and have a vertical laminar hood
what are isolators?
“glove-boxes”
which types of isolators should be used for hazardous and non-hazardous drugs?
hazardous: compounded aseptic containment isolators which have negative pressure
non-hazardous: compounded aseptic isolators which have positive pressure
drugs made in the segregated compounding area have what BUD?
<=12 hours
what is the gloved fingertip test?
it is to evaluate gloving and garbing techniques.
A pass is three consecutive gloved fingertip tests with zero CFUs.
How often should a gloved fingertip and media-fill test be conducted?
low to medium risk compounding - annually
high risk compounding - semiannually
what is the media-fill test?
to evaluate the aseptic technique of personnel.
a fail is if the media becomes turbid at or before 14 days
cleaning and disinfecting surfaces is done with what and how?
cleanest to the dirtiest area and with 70% isopropyl alcohol
how often should the work surfaces, floors, and counters of the compounding area be cleaned?
daily
how often should the PEC be cleaned?
at the beginning of shift every 30 minutes of continuous use after spills whenever contamination is suspected before and after each batch
how often should the ceilings, walls and storage shelves be cleaned?
monthly
what do IV solutions need to be?
isotonic
pH close to neutral
in non-PVC bags if leaching or sorption issues
