STERILE Flashcards
Moist heat
(autoclaving, steam sterilization)
Sterilizes by
- *PROTEIN DENATURATION**
- *121*C for 15 min (15psig)**
destroys bacteria & spores, need to remove air
Parenteral products / media / GLASS / STEEL / UTENSILS / Media
DRY HEAT
Oven sterilization
DESTROY MICROORGANISMS & PYROGENS
High heat = 160*C
Glass / stainless steal
loss of moisture / protein denaturation / oxidation
Non-Thermal Filtration
DRUG SOLUTION
Microbial & Pyrogen Free
0.22 mucron filter
CLASS 100 = ISO 5 ROOM
Non-Thermal Filtration
RADIATION STERILIZATION
GAMMA RADIATION
Cobalt 60
to sterilize
IV Admin sets / DISPOSABLE GOWNS / PLASTICS
DNA DESTRUCTION
Non-Thermal Filtration
Room AIR & Laminar Aiflow hood air
PRE FILTERS
0.22 - 0.45 micron filters
flow too high = LEAK / Damage
too LOW = plugged
CHEMICAL STERILIZATION
ETHYLENE OXIDE & Other Cemicals
used for
PLASTICS & other disposable medical devices
FASCILITY
ALKYLATION –> block metabolic pathways
Pyrogens
Sterilization
from microorganisms / gram - & positive / fungi
induce fever / chills / pain / malaise
can NOT be removed by filtration
need HIGH TEMP sterilization
LAL
Limulus Amebocyte Lysate
Coagulation test
TESTED ON RABBITS
for PYROGENS
Prefilters & membrane Filter
Size
Air vilocity & # of air changes/time important
0.22 - 0.45 micron
to
remove particulate from AIR
BACTERIA is transported via particulate
STABILITY
No significant changes in the product during SHELF LIFE
changes include:
- *Chemical**
- *potency of active ingredient**
Physical
- *Microbiological**
- *sterility**
Biophamaceutic / Therapeutic
Toxicity
High Temperature studies can predict WHAT?
Packages must maintain integrity throughout shelf life including normal use (multiple needle punctures in vials).
