What are the 4 characteristics that make a drug hazardous?

- Teratogenic
- Causes organ toxicity at low doses
- Genotoxic (damages the DNA)
What must be included in a sterile compounding space?
- anteroom
- buffer area
- primary engineering control (PEC) or a segregated compounding area (SCA)
What requirements must be met for a non-sterile HD to be prepared in a C-PEC inside a C-SEC?
- The C-SEC must maintain ISO 7 air
- There must be separate sterile and non-sterile C-PECs kept at least 1 meter apart
- Particle-generating activity, such as working with powders, cannot be performed when any sterile compounding is being performed in the same C-SEC
C-PECs (containment primary engineering control) and C-SECs (containment secondary engineering control) must have ______
negative air pressure
In space where non-sterile HDs are compounded, there must be at least __ air changes per hour (ACPH)
12
In space where sterile HDs are compounded, there must be at least __ air changes per hour (ACPH)
30
What does it mean when air that has been contaminated with HDs must be externally exhausted?
The air is moved out of the space and cannot be recirculated and returned to the room
What is an alternative option to an external exhaust (for non-sterile HD compounding only)
Redundant-HEPA filters
What is a primary engineering control (PEC)?
The sterile hood
What is a secondary engineering control (SEC)?
The buffer room or sterile compounding room (the C-PEC is placed here)
What is a class II biologic safety cabinet (BSC)
The chemo hood for sterile chemo drugs and other sterile HDs (aka a C-PEC)
What is a Compounding Aseptic Containment Isolator (CACI)
The isolator glove box for HDs
CAI is for non-HD
The International Standards Organization (ISO) sets the standards for air quality, which is determined by the number and size of ___ per ___ of air
Particles per volume (the lower the particle count, the cleaner the air)
In critical areas that are closest to exposed sterile drugs and containers (i.e. inside the sterile hood) the air must be at least ISO __. Particles are included in this count if they are ____ in size or larger
5
0.5 microns
The buffer area (or SEC) must be at least ISO __
7
The anteroom (the room adjacent to the SEC, where hand washing and garbing occurs) must be at least ISO __ if it opens into a positive-pressure buffer area (non-HD sterile compounding) or at least ISO __ if it opens into a negative-pressure buffer area (HD sterile compounding)
8
7
HEPA filters are >99.97% efficient in removing particles as small as ____ wide or larger, including bacteria, fungi, viruses, and dust
0.3 microns
In a ___ airflow biologic safety cabinet (BSC) or C-PEC, the HEPA filter is at the top of the sterile hood
Vertical
In a ____ airflow, or PEC, the HEPA filter is at the back of the sterile hood
Horizontal (laminar airflow workbench)
Compounding should be done in the cleanest air, which is the air coming directly out of the HEPA filter. This is called the _______
Direct compounding area (DCA)
The air from the HEPA filter is called the ____
First air
The HEPA filter must be recertified by a specialist every _ months & any time a PEC has been moved
6
Running down the center of the anteroom is a large visible line called ____, which separates the room into clean and dirty sections
the line of demarcation
Air pressure inside the PEC and inside a non-hazardous SEC can both be ____ (positive or negative)
Positive
With hazardous compounding, the C-PEC and the C-SEC must have ____ pressure to keep the toxic air contained in the space (positive or negative)
Negative
Another name for and isolator PEC/glove box?
Where are they located?
compounding aseptic isolators (CAI) or compounding aseptic containment isolators (CACI)
Located in a segregated compounding area (SCA) or C-SCA for HD
The maximum beyond-use dates (BUD) for CSPs made in an isolator in a segregated compounding area (SCA) is _____
12 hours
If the anteroom is ISO 8, the air will be dirtier than inside the SEC. To keep the air from the anteroom out, the SEC will need to have _____ air pressure to push the air out of the SEC and into the anteroom
Positive
For sterile, non-hazardous preparation, ____ laminar airflow is used
Horizontal
For sterile hazardous preparation, ___ laminar airflow is used
Vertical
Adequate aseptic technique in hand hygiene, garbing and gloving is demonstrated by passing which test?
The gloved fingertip test
Adequate aseptic technique in sterile drug preparation is demonstrated by passing which test?
