433 - Midterm 1 Flashcards
Compounded Sterile Products
CSPs
Sterile Drugs
Injections
Irrigations
Pulmonary Inhalations
Opthalmics
Implants
What type of Pressure?
Airflow is flowing INWARD (into hood or room)
and
vented to the outside
NEGATIVE PRESSURE
Required for Hazardous drug prep.
Buffer Area at least < Iso 7
Ante area that opens into NEG-ressure room < iso 7
What ISO must be the CRITICAL AREAS ?
(hood / closest to sterile drugs)
ISO 5
When to CLEAN the PEC?
primary Engineering Control = Hood / isolator
Iso Class 5
Beginning of each Shift
Before & after a batch
After Spills
Anytime CONTAMINATION is suspected
How often do we clean
Counters / Work surfaces / Floors
DAILY
How often do we clean?
Walls / Ceiling / Shelves
MONTHLY
BSC = Chemo Hood
Type of Hood
NEGATIVE PRESSURE hood
used to prepare Hazardous CSPs
Isolators = Glove Boxes
Type of Hood
Completely enclosed type of PEC
2 Types:
CAIs = Positive Pressure, for non-hazardous drugs
CACIs (containment)
NEGATIVE pressure for HAZARDOUS DRUGS
IVLFZ
Integrated Verical Laminar Flow Zones
Type of Hood
HEPA FILTER IN CEILING
over stainless steel work tables
“open Architecture”
SVP vs LVP
Small <100mL
Large >100mL
Where are HAZARDOUS DRUGS prepared?
VERTICAL BSC
in
NEGATIVE PRESSURE FASCILITY
USP 800 = Hazardous Drugs
RED SHARPS WASTE
SHARPS = RED
Needles / Syringes
Broken Ampoules / Vials
WITH or WITHOUT drug remaining
Black Waste
Pharmaceutical / Drug Waste
RED BIOLOGICAL WASTE
Blood / Human Products
Yellow Waste
Yellow = HAZARDOUS DRUGS
ALL material that were in the hood while compounding
Outer gown materials too
When can Drug go into general trash?
- *<3%** of drug remaining
- *intact glass can go into general trash**
Broken Glass w/ <3% drug can go into glass trash
More Drug –> Pharmaceutical Black WAste
More drug in glass –> Sharps container
Incompatibility
When 2+ ingredients interact causing an
UNDESIRABLE / ADVERSE AFFECT
VVVV
Product +/- Efficacy
Ex.
Precipitation Reaction
INSTABILITY
When a compound
UNDERGOES DEGRADATION
Ex.
Rotting Food –> no longer edible
TNA
Total Nutrient Admixture = TNA
aka TPN = 3 in 1 infusion
PN + IV Fat Emulsion
IVFE considerations
IV Fat Emulsion = Lipids
Can CRACK with:
freezing or heating
HIGH pH
contact with HIGH CONCENTRATIONS OF DEXTROSE
Seperate Dextrose & lipids
Order of Mixing for TPN
LIPIDS & DEXTROSE SEPERATE!
PROTEIN IN BETWEEN
MULTIPLE VITAMIN NEAR LAST
due to yellow color
- *Phos + Calcium**
- *also Avoid MAG Sulfate (do not DIRECTLY mix)**
Calcium Phosphate Solubility Curve
- *Concentration BELOW the curve = OKAY**
- *Safety Zone Area**
Curve will shift up into the Danger Zone Area
As pH increases (acidic) from AA’s
Physical Incompatibilites
that can lead to PRECIPITATION
Dilution of non-aqueous solutions
Mixing of APIs formulated at VARYING pH
Mixing of SALTS
Charged SURFACTANTS
+ Protein or +Preservative
HYDROSCOPICITY
is also a physical incompatibility
