where a degree of occlusion is desired.

A

OINTMENTS

65
Q

These are semisolid preparations for external application to skin or mucous membranes. Their composition softens but does not melt upon application to the skin.

A

OINTMENTS

66
Q

Types of Ointments

A

HYDROPHOBIC OINTMENT
WATER-EMULSIFYING OINTMENT
HYDROPHILIC OINTMENT

67
Q

These are usually anhydrous and can absorb only small amounts of water.

Typical bases used for their formulation are water-insoluble hydrocarbons such as hard, soft and liquid paraffin, vegetable oil, animal fats, waxes, synthetic glycerides and polyalkyl siloxanes.

A

HYDROPHOBIC (LIPOPHILIC) OINTMENTS

68
Q

It can absorb large amounts of water.

They typically consist of a hydrophobic fatty base in which a w/o agent, such as wool fat, wool alcohols, sorbitan esters, mono glycerides, or fatty alcohols can be incorporated to render them hydrophilic.

A

WATER-EMULSIFYING OINTMENT

69
Q

They may also be w/o emulsions that allow additional quantities of aqueous solutions to be incorporated. Such ointments are used especially when formulating aqueous liquids or solutions.

A

WATER-EMULSIFYING OINTMENT

70
Q

Its bases are miscible with water. The bases are usually mixture of liquid and solid polyethylene glycols (macrogols).

A

HYDROPHILIC OINTMENT

71
Q

These are homogeneous, semi-solid preparations consisting of opaque emulsion systems.

Their consistency and rheological properties depend on the type of emulsion, either water-in-oil (w/o) or oil-in –water (o/w), and on the nature of the solids in the internal phase.

A

CREAMS

72
Q

They are intended for the application to the skin or certain mucous membranes for protective, therapeutic, or prophylactic purposes, especially where an occlusive effect is not necessary.

A

CREAMS

73
Q

These are semisolid dosage forms that contain one or more drug substances dissolved or dispersed in a suitable base, usually oil in- water emulsion or aqueous microcrystalline dispersion of long-chain fatty acids or alcohols that are water washable and are cosmetically and aesthetically acceptable.

A

CREAMS

74
Q

These are usually homogeneous, clear, semi-solid preparation consisting of a liquid phase within a three-dimensional polymeric matrix with physical or sometimes chemical cross linkage by means of suitable gelling agents.

A

GELS

75
Q

These are semisolid systems that consist of either suspensions of small inorganic particles or large organic molecules interpenetrated by a liquid.

A

GELS

76
Q

Its bases usually consist of liquid paraffin with polyethylene or fatty oils gelled with colloidal silica or aluminium or zinc soaps.

A

HYDROPHOBIC GEL (OLEOGEL)

77
Q

Its bases usually consist of water, glycerol, or propylene glycol gelled with suitable agents such as tragacanth, starch, cellulose derivatives, carboxyvinyl polymers, and magnesium aluminium silicates.

A

HYDROPHILIC GEL (HYDROGEL)

78
Q

These are homogeneous, semi-solid preparations containing high concentrations of insoluble powdered substances (usually not less than 20%) dispersed in a suitable base.

A

PASTES

79
Q

These are usually less greasy, more absorptive, and stiffer in consistency than ointments because of the large quantity of powdered ingredients present. Some pastes consist of a single phase, such as hydrated pectin, and others consist of a thick, rigid material that does not flow at body temperature.

A

PASTES

80
Q

These are semisolid dosage forms that contain one or more drug substances incorporated in a base with large proportions of finely dispersed solids.

A

PASTES

81
Q

It is an ancient form of topical medication also known as a cataplasma.

It is a soft mass of vegetable constituents or clay, usually heated before application.

A

POULTICES

82
Q

It is prepared by mixing and heating dried, heavy kaolin and boric acid with glycerine.

A

KAOLIN POULTICE BP

83
Q

Its purpose is to provide evidence on how the quality of a drug substance or drug product varies with time under the influence of a variety of environmental factors such as temperature, humidity, and light, and to establish a re-test period for the drug substance or a shelf life for the drug product and recommended storage conditions.

A

STABILITY TESTING

91
Q

The stability studies should be conducted on the drug substance packaged in a container closure system that is the same as or simulates the packaging proposed for storage and distribution.

A
