digoxin
foscarnet
mannitol
What drug is known to cause severe tissue injury even via SC, IM, intra-arterial

do not give to children <2y
What is the name of the book that is the primary compatibility and stability resource?
the handbook on injectable drugs (Trissel’s)
or the King guide to parenteral admixtures. (King’s)
can also find info in the package insert
Chemical instability causes drug degradation or toxicity due to what type of reaction?
hydroloysis
OR
oxidation
OR
decomposition
Physical incompatibilities occur between a drug and one of the following:
container (PVC)
diluent (solution – dextrose)
another drug
The majority of PVC containers use _____ as a plasticizer to make the plastic bah more flexible. Why is this not good in some instances?
DEHP
it can leach into the solution and it is toxic. can harm the liver and testes
Absorption vs adsorption?
absorption: occurs when the drug moves into the PVC container
adsorption: occurs when drug adheres to the container
either will reduce the drugs concentration

polyolefin
polypropylene
glass containers
Insulin absorbs/adsorbs to PVC?
adsorbs! (sticks to the PVC)
however, clinicians adjust the rate of insulin infusions to obtain BG control regardless of the type of IV container/tubing used
