Q

 These bases are water soluble; however, the dissolution process is very slow.

 These do not melt at body temperature
but rather dissolve slowly in the body’s
fluids. Therefore, the base needs not to be
formulated to melt at body temperature.

 In rectum and vagina, where the amount of fluid is very small, they dissolve very slow, but they soften and spread.

Q

May be prepared by dissolving granular
gelatin (20%) in glycerin (70%) and
adding a solution or suspension of the
medication (10%).

A

GLYCERINATED GELATIN

43
Q

May have a tendency to absorb moisture
due to the hygroscopic nature of glycerin,
they must be protected from atmospheric
moisture for them to maintain their
consistency.

A

GLYCERINATED GELATIN

44
Q

Is most frequently used in the preparation of vaginal suppositories, where the prolonged localized action of the medicinal agent is usually desired.

A

GLYCERINATED GELATIN

45
Q

Is slower to soften and mix the physiologic fluids than in cocoa butter and therefore provides a more prolonged release.

A

GLYCERINATED GELATIN

46
Q

This is a type that is used to prepared with Cocoa/Cacao Butter or Theobroma Oil.

A

FIRST TYPE

47
Q

will soften when used with:
Phenol, Camphor, Chloral hydrate, and other volatile oils. However this can be remedied by the addition of: Wax or Spermaceti to raise the melting point in the warmest weather.

A

CACAO BUTTER

48
Q

Acts by melting at body temperature.

A

THEOBROMA OIL

49
Q

Are those prepared with Glycerin and
Gelatin

A

SECOND TYPE

50
Q

o Are water-soluble or water miscible
o Are employed to provide a continuous
medicating or germicidal action
o By mixing the aqueous solution of
suspension of the medicament with
glycerin and gelatin.

A

SECOND TYPE

51
Q

Are the Glycerin or Soap suppositories
shaped from Castille soap

A

THIRD TYPE

52
Q

o This performs their function in part
mechanically and in part by dissolving and
producing some irritation.
o Their chief value is as stimulation to
peristalsis, through their presence in the
rectum.
o They are mostly for small children to avoid the use of laxatives

A

THIRD TYPE

53
Q

3 methods of preparation:

A

MOLDING (FUSION)
COMPRESSION
HAND ROLLING AND SHAPING

54
Q

 Is the principal way of making suppositories commercially.
 Capable of producing 6-12 or more suppositories
 Molds are made of Stainless steel,
Aluminum, Brass or Nickel-Copper alloys, or plastic.
 Primary bases used are: Cocoa butter,
Polyethylene glycol, Glycerinated gelatin
 Mineral oil is used as lubrication.
Suppository Molds:

A

SUPPOSITORY MOLDS

55
Q

Preparation:
 Melting of the base
 Incorporation of any of the medicaments
 Pouring the melt into molds
 Allowing the melt to cool and congeal into suppositories
 Removing the formed suppositories from the mold

A

MOLDING

56
Q

lubrication is seldom necessary as these
materials contact sufficiently on cooling to
separate from the inner surfaces and
allow easy removal.

A

COCOA BUTTER OR POLYETHYLENE GLYCOL

57
Q

lubrication is usually
necessary. A thin coating of mineral oil
applied within the finger to the molding
surfaces usually suffices.

A

GLYCERINATED GELATIN

58
Q

 Is generally employed when cocoa butter is used as a base.
 Capable of producing a 2 g suppository.

A

COMPRESSION

59
Q

Preparation:
 Uniform mixture of drug and base (hand-rolling method)
 Mixture is placed into a chamber mold.
 Mold is then cooled.

A

COMPRESSION

60
Q

Involves molding the suppository with
the fingers after the formation of
plastic mass.

A

HAND ROLLING AND SHAPING

61
Q

must be-stored below 30°C and preferably in a refrigerator (2°C to 8°C)

A

into a naturally occurring (nonsurgical)
body cavity other than the mouth or
rectum, including the vagina and urethra.

A

INSERTS

65
Q

Are usually ovoid in shape and are
accompanied in their packaging with a
plastic inserter, a device for easy
placement of the tablet within the vagina.

A

VAGINAL INSERTS

66

It contains the same types of anti-infective
and hormonal substances as the vaginal
suppositories.

A

VAGINAL INSERTS

67
Q

Are a convenient form for
administering topical medications.

A

MEDICATION STICKS

68

 Their development is interesting
because it involves the history of
cosmetics, which parallels human
history.
 Are cylindrical in shape and generally
range from 5-25 g.

A

MEDICATION STICKS

69

balm sticks which became available in the
early 1940’s.

A

Today,________ provide pharmacists, patients and primary care providers with a unique, convenient, relatively stable, easy-to-prepare dosage form for the topical delivery of drugs

A

medication sticks

71
Q

are prepared
similar to suppositories except that
the melt is poured into the
administering device, or tube.

A

MEDICATION STICKS

72
Q

They come in different sizes and
shapes, are readily transportable,
and can be applied directly to the
affected site of the body.

A

MEDICATION STICKS

73
Q

The stick is pushed up from the
bottom or using a screw-type device
to raise the stick.

A

MEDICATION STICKS

74
Q

They are generally packaged in an
applicator tube for topical
administration, and the applicator can
be adjusted to continually expose
new, fresh stick from inside the tube

It facilitates the passage of therapeutic
quantities of drug substances through the
skin and into the general circulation for their systemic effect.

A

TRANSDERMAL DRUG DELIVERY SYSTEMS (TDDSs)

76
Q

 The blood concentration needed to
achieve therapeutic efficacy may be
determine by comparative analysis of
patient response to drug blood levels.

 It is considered ideal if the drug
penetrates through the skin to the
underlying blood supply without drug buildup in the dermal layers.

A

TRANSDERMAL DRUG DELIVERY SYSTEMS (TDDSs)

77
Q

Are designed to deliver a constant and
controlled dosage over extended periods of

consists of an adhesive material
containing 5% lidocaine, which is applied
to a nonwoven polyester felt backing and
covered with a PET film release liner. The
release liner is removed just prior to
application.
