Sterile water for injection

OR

Bacteriostatic water for injection

8

Sterile compounding req personnel trained and evaluated ANNUALLY for competency in what areas?

Aseptic techniques

Environmental control

End-pdt evaluation

9

What's the req of preparing an injectable?

Certified sterile compounding environment must be either:

ISO class 5 (class 100) laminar air flow hood

Within ISO class 7 (class 10,000) clean room with positive pressure differential relative to adjacent areas

OR a barrier isolator that provides a ISO class 5 (class 100) environment for compounding

Clean room garb (low-shedding coverall, head cover, face mask and shoe covers)

Syringe

14

What are pipettes used for?

Liquid that 1.5mL or less of liquids

15

Which is the most commonly used mortars and pestle?

Wedgewood or porcelain

16

What's Wedgewood or porcelain best for?

Best for reducing particle size of dry powders and crystals

17

What mortar and pestle is preferred for blending powders or pulverizing soft material? Why?

Porcelain

Bcuz it has a Smoother surface than wedgewood

18

What type of mortar and pestle is used for liquids and chemicals that are oily or that may stain porcelain, including many chemo agents?

Glass mortar & pestle

19

What's glass mortar & pestle preferred for?

For mixing liquids and semi-soft dosage forms

20

What's glassine weighing paper used for?

Weighing ointments and some dry chemicals

21

What type and size of spatula blades are used?

Large metal (stainless steel) spatula blades

Small spatula (< 6 inches) blades are used for transferring pdt from large spatula to jars

22

What's plastic spatulas used for?

Used for chemicals e.g. Potassium, iodine, that can react with stainless steel blades

23

What are compounding slabs also called? Use? Xtic?

Compounding slabs are also called Ointment slabs

They are gen glass

And have nonabsorbent surfaces

24

What's levigation?

Process of reducing the size of a particle of solid by triturating it

25

What's a wetting agent?

Small amt of liquid used during levigation in which the soiplid is NOT soluble

26

List the levigation agents used for aqueous systems (o/w dispersions)

Glycerin

Propylene glycol

Polyethylene glycol 80

27

List the levigation agents used for oleaginous systems (w/o dispersions)

Mineral oil (light & heavy)

Castor oil

Cottonseed oil

Tween 80

28

What's trituration!

Process of REDUCING fracturable POWDER substances into FINE PARTICLES by rubbing (or grinding) them with a mortar & pestle or on an ointment slab

29

What's extemporaneous compounding?

Extemporaneous compounding refers to a comp prepared WITHOUTa specific formula from an official compendium and made especially to fill the needs of a specific pt

30

What's an emollient?

A SINGLE agent that's used to soften and smooth the skin.

31

What's an emulsion?

Emulsions are 2-phase system of 2 immiscible liquids, one of which is dispersed through the other as small droplets.

An emulsion could be oil in water or water in oil

32

What's an emulsifier?

Emulsifiers (or emulgent) is used to stabilize the emulsion

33

Role of emulsifiers?

Emulsifiers are gen surfactants (used to reduce surface tension so that the 2 subst can move closer to each other)

34

Do emulsions from a suspension?

No! They are 2 immiscible liquids

35

List the most common emulsifiers

Lipophilic esters of sorbitan:

Arlacel

Span

36

List hydrophilic esters

Myrj

Tween

37

List other commonly used emulsifiers

Polyethylene glycol (PEG)

Acacia

Glyceryl monostearate

Sodium laurel sulfate

38

What's the hydrophilic-lipophilic balance (HLB) number?

HLB determines how much surfactant will be req to form the mixture together

39

What's the implication of a low HLB number?

Agents with low HLB number are more oil soluble

40

What's the implication of a high HLB number?

Agents with high HLB number are more water soluble

41

Whats the HLB scale range? Midpoint?

0 - 20

10 (breakpt btw water and oil solubility)

42

T/F? A medication packaged in an ointment will have a higher potency than the same med packaged in a cream or lotion?

True

Mometasone (Elocon) ointment is high-potency and Mometasone (Elocon) cream is low-medium potency

43

What are lotions?

Lotions have the MOST water and are most often o/w (small amt of oil)

E.g.

Keri

Cetaphil

44

What are creams?

Emulsions of about half oil and half water

E.g. Terbinafine (Lamisil AT) antifungal cream,
Docosanol (Abreva) antiviral cream

45

What are ointments?

Ointments are ~ 80% oil and 20% water

46

What are ointments used for?

Occlusive benefit - they block (trap in) moisture (preferred for dry or dry/cracked skin)

Thickest ointments and also used as protective barriers

E.g.
Triple paste medicated diaper rash ointment

48

List examples of gels

Benzoyl peroxide

Erythromycin topical acne gel (Benzamycin)

49

Uses of gels?

Used as thickeners

50

What are solutions?

Liquid preparations of soluble chemicals dissolved in solvents such as water, alcohol or propylene alcohol

51

Whats a suspension?

2- phased of finely divided solid in liquid medium

52

A suspension must be deflocculated. What does this mean?

This means that the repulsive forces btw particles predominate so that the particles in the suspension repel each other and remain as discrete, single particles

53

Xtics of a suspension?

Suspensions should;

Settle quickly
Re-dispense by gentle shaking
Have uniform particles that are of small size

54

What are suppositories?

Suppositories are solid dosage forms used to deliver medicine into rectum, vagina or urethra

55

What tablet formulation is the most common dispensed in everyday practice (often the least the expensive)?

56

What may tablets also contain?

Excipients (also called binders)

May present a problem for pts with lactose- intolerance
