USP 797
Sterile compounding
USP 800
Handling hazardous drugs
NIOSH
Determines which drugs are hazardous
ISO
Sets standards for air quality
Which is determined by the number of particles per volume of air of a specified particle size
ISO for critical areas (inside the hood)
ISO 5
ISO for buffer room or anteroom
ISO 7
A graduate should not be used to measure volumes less than ____ of the graduate’s capacity
20%
Surfactant
Lowers the Surface Tension between two ingredients to make then more miscible or easier to mix together
Emulsion
Liquid dispersed in a different liquid
Oxidation
Loses electrons
Reduction
Gains of electrons
Hydrolysis
Water causes the cleavage of a bond in a molecule
What 3 functional groups are susceptible to hydrolysis
Esters
Amides
Lactams
Photolysis
UV light exposure causes breakage of covalent bonds
4 compounds sensitive to lights
Ascorbic acid (Vitamin C)
Folic acid (Vitamin B9)
Nitroprusside (a vasodilator like Nitrostat)
Phytonadione (Vitamin K1)
Ointment, Cream or Lotion …… Which has more water?
Ointment: 80-100% oil 0-20% water
Cream: 50:50 oil and water
Lotion: most water
Solution
A solute dissolved in a solvent
Suspension
Solid dispersed in a liquid
Eutectic mixture
The combination of the ingredients when mixed will melt at a lower temperature than either of their individual melting temperatures
BUD for non-aqueous formulations
Earliest expiration date
or
6 months
BUD for Water-containing oral formulations
14 days
BUD for Water containing topical semisolid form
30 days
Low-risk sterile compounding
Uses 1 - 3 additives that are supplied as sterile
Medium-risk sterile compounding
Uses more than 3 additives that are sterile
High-risk sterile compounding
Non-sterile ingredients and equipment
Osmolarity
Express the solute concentration and includes all solutes
Tonicity
Express the solute concentration and includes only the solutes that do not cross the vasculature
What happens when you inject hypertonic saline in a peripheral vein
The high concentration of solutes relative to the concentration in blood will cause water to move out of the red blood cells, in an attempt to dilute the solute concentration
What is the highest acceptable Osmolarity allowed for peripheral IV?
~900 mOsmol/L
anything higher than this should be administered in a central line
What happens when a preparation has lower osmolarity than blood
RBC absorb fluid causing hemolysis
What is the lowest osmolarity that should be administered IV
~154 mOsmol/L
this is the osmolarity of 1/2 normal saline
