8
Q
Buffers
A
- Keep pH stable in a certain range
- Which ones used depends on the goal pH range
- Acids for acidic pH, hydroxides or -ate for basic, lots of phosphate examples for neutral pH
9
Q
Hydrophilic Solvents
A
- Water (sterile and otherwise)
- Alcohols
- Glycols
10
Q
Water
A
- Potable - used to wash hands and equipment
- Distilled - used to reconstitute and prepare non-sterile compounding products
- SWFI - free of bacterial endotoxins (pyrogens) and used to sterile compounding
11
Q
Alcohols
A
- High miscibility with water and can dissolve solutes that would be insoluble in water alone
- Benzyl alcohol: also used as a preservative and for its fragrence
- 70% IPA: preferred disinfectant in sterile compounding
12
Q
Glycols
A
- Low freezing points and high boiling points
- PEG is used as a surfactant, solvent, plasticizer, lubricant, and a base (water soluble and miscible)
- PEG also has an increased half life when bound to a protein drug
- Polybase - PEG mixture used as a suppository base, good emulsifier
13
Q
Hydrophobic Solvents
A
- Oils/Fats - used as delivery vehicles, lipophilic/hydrophobic compounds
- EX: Mineral oil (ingredient in BabyOil)
14
Q
Ointments
A
- 0-20% water, some are mixed with humectants to draw water into skin
- Ex bases: petrolatum, Polybase, Aquaphor, Aquabase
15
Q
Oleaginous Ointments
A
-No water, only oil containing
AKA Hydrocarbon base
-Ex: Petrolatum (Vaseline, petroleum jelly)
