compounding I: basics Flashcards
1
Q
U.S Pharmacopeia
A
sets the standard for compounding preperations.
795 for non-sterile
797 for sterile
+800 if it is hazard..
2
Q
non-sterile compounding
A
- prepare a dose or formulation taht is not commercially available: such as
—> Changing a solid tab to liquid
—> compounding an ointment 10% when only 5% and 15% available - avoid an excipient (ex. dye, gluten)
- add a flavor to med
non-sterile prep admin include: by mouth, via tube, rectally, vaginally, topically, nasally or in the ear
3
Q
USP 795 divides non-sterile compounding into three categories based on complexity
A
- simple: following instructions (kits, w/ step by step)
- moderate: specialized calculations or procedures, or making a preparation that no established stability data. (ex. mixing two topical creams when stability data for mixture is not available)
- complex: requires specialized training, equipment, facilities or procedures (ex. transdermal dosage forms)
4
Q
specifically designated for non-sterile compounding
A
- separate location
- performed in ambient air (room air)
- separated from the dispensing part of pharm
- all components, equipment should be stored off the floor
two types of water:
- portable (drinkable)
- purified (distilled) for water-containing formulations and for rinsingequipment..

27
high efficiency article air filters
HEPA are >99.97% efficient at removing particle as small as 0.3
must be recertified every 6 month
28
vertical flow
HEPA filter at at the top of the sterile hood
29
laminar flow
HEPA filter at the back- horizontal flow
30
direct compounding and first air
- PEC provides ISO 5 air quality for sterile compounds. air coming directly out of HEPA is first air
- do not obstruct first air
- do not block airflow
to prevent contamination, injection port of the villa and syringe needle must be kept in the first air
31
Prevent contamination of air in PEC
- wipe off outsides of all material w/ 70% isopropyl alcohol before bring into PEC
- open packages along designed tear lines
- compound 6" inside the sterile hood
- move waste outside shortly after it is created
32
non-hazardous compounding
pressure inside PEC and SEC is positive
33
hazardous
PEC (C-PEC) and SEC (C-SEC) is negative pressure
34
types of sterile compounding area
- cleanroom suite: one or more ISO-5 PECs (sterile hoods) inside an ISO 7 buffer room that is entered through an adjacent anteroom
- segregated sterile compounding area (SCA) w/ ISO 5-PEC: sterile hood often an isolated (glovebox) w/ closed front. -unclassified air

as part of assessment of risk (AoR), standard operating procedures (SOPs) must be developed:
- putting HDs in distinctive shelf bins to alert staff
- wearing ASTM D6978 rated gloves when counting or packaging drugs
- dedicating a counting tray and spatial for HDs and decontaminating both after use
- placing prepared HD containers into a sealable plastic bag
AoR doc reviewed every 12 months or whenever a new drug or dosage form is stocked or used
50
HD hoods and buffer room include word containment
C-PEC
C-SEC
C-SCA
CACI
C-PEC is located inside C-SEC or C-SCA
51
type of C-PEC for HD
BSCs
biological safety cabinets have vertical laminar airflow and negative air pressure
for sterile hazardous drugs
52
type of C-PEC for HD
CVEs
containment ventilated enclosures are powder containment hood w/ HEPA filter air and negative air pressure
used for non-sterile compounding only
53
type of C-PEC for HD
CACIs
are closed-front C-PECs (gloveboxes) located in buffer room (SEC) but are often located in C-SCA
external vent, negative air pressure
54
it is perferred that non-sterile and sterile compounding space separate, an exception can be made to prepare a non-sterile hazardous drug in a C-PEC inside a C-SEC if these requirements are met
- C-SEC must maintain ISO 7
- separate sterile and non-sterile C-PEC in same C-SEC y at least 1 meter apart
- particle-generating activity (powders) can not be performed at the same time
- occasional non-sterile HD compounding can be completed C-PEC but it must be properly decontaminated, cleaned, and disinfected before using again with sterile HDs
55
negative pressure
C-PECs, C-SECs, and C-SCAs
56
air changes
non-sterile HD (C-SEC) 12ACPH
sterile C-SEC 30 ACPH
C-SCA 12 ACPH
ACPH- air changes per hour
57
hazardous drug storage
stored separately from non-hazardous drugs, negative pressure 12 ACPH
58
temp monitoring
SEC buffer room- once daily, kept at 20 C or 68F or cooler
refrigerator and freezer monitor daily unless they contain vax which is twice daily monitoring
refrigerator: 2 to 8C
freezer: -25 to -10C- w/vax -50 to-15 per CDC
59
air sampling
every 6 months
60
Keep PEC running
running at all times,
if there is a power outage, all compounding must stop, and PEC cleaned w/ germicidal detergent and then disinfected w/ sterile 70% isopropyl alcohol
must be on for least 30min before compounding
61
deactivation and decontamination
2%bleach (sodium hypochlorite) or peroxide
62
cleaning
germicadal detergetn such as
Quat, ammonium, phenolics (removes dirt and microbial contamination)
63
Disinfection
sterile 70% isopropyl alcohol (PA)
inhibits or destroys microorganism; required in sterile compounding
64
black waste bin
black is for bulk HD waste: any containers (drug vials, IV bags) that contain a clearly visible amount of HD and any supplies that were used to admin HDs or to clean HD spills
65
Yellow waste bin
trace HD waste: empty syringes, IV bags, used PPE, including gowns, gloves, masks, and shoes
red sharps contain is only for non-hazardous sharps
66
disposal hazard
- outer chemotherapy gloves worn during compounding is discarded in yellow waste bin inside C-PEC. or put in a sealable bag if discarding outside
- chemo gown and outer shoe covering ist take off before exiting the negative-pressure area and thrown in yellow bin
67
garb for HD
general
Nonsterile HD
- double ASTM D6978 (chemotherapy) rated golves when compounding or cleaning up spills
- single gloves can be used for HD receiving and storage
- double gloves, gown, a mask and
- disposable pad to protect the work surface
68
garb for HD
sterile HD
