Q

Na lauryl sulfate

A

used in powder forms as surfactant to neutralize the static charge and keep powder from floating away

30
Q

sieve

A

used to sift powder and ensure a uniform particleeutectic misxtures size. sometimes a brush or spatula is used to force particles thru the sieve. sieve number is amt holes per in.

31
Q

eutectic mixture

A

melt at lower temp than the melting temps of the individual components. lubant powder can keep it dry - Mg oxid, Mg carbonate, or kaolin.

32
Q

caps made of

A

gelatin (animal) or hypromellose (veg)

33
Q

plasticizers for caps

A

glycerol and sorbitol to make caps less brittle and more flex

34
Q

molding a tablet

A

most common in compounding (compressed tablet is most common for manu). use alcohol or water to moisten powder, forms a paste, mold into tab, allow to dry.

35
Q

38
Q

preservatives

A

prevent bacteria growth. chlorhexidine can be presevative or antiseptic for surgical scrubs. in opthalmics: EDTA, Na benzoate, benzoic acid, benzalkonium Cl, thimersosal

39
Q

suppository base

A

stay intact for insertion but melt once inserted. hydrogenated veg oil or gelatin is used. also cocoa butter.

40
Q

ointments

A

contain least amt of water. 5 types depending on base: oleaginous (oily), absorption, water-in-oil (w/o) emulsion bases, oil-in-water (o/w) emulsion bases, or water-soluble bases

41
Q

making ointments

A

triturate the powders using levigating agent. mix using geometric dilution. some need heat so melt ingred with highest melting point then add the others in order of dec melting point.

42
Q

gels

A

semisolids interpenetrated with liquid. PLO gel (pluronic lecithin organogel) is used for transdermal drug delivery (lipophilic base in a water and alcohol vehical)

43
Q

Q

rectal suppositories

A

treat conditions that are systemic or local (inside rectum or GI)

45
Q

emulsion

A

liquid dispersed in liquid. 2 phase heterogeneous mixture. oil in water (oil drops in water vehicle) or water in oil

46
Q

emulsifier

A

surfactant or detergent used to reduce the surface tension between oil and water, allows the phases to come closer together. choose emulsifier (amphiphillic molecule) for emulsion based on HLB number (hydrophillic-lipophillic balance)

47
Q

discontinuous phase

A

phase present as drops. aka dispersed aka internal phase

48
Q

continuous phase

A

phase present in which drops are suspended aka external phase.

49
Q

suspension

A

solid dispersed in liquid. 2 phase heterogenous mixture. wetting or levigating agent is the surfactant used to incorporate an insolu drug into a liquid
