{{c1::Emulsions}} are defined as preparations containing a mixture of two (or more)
{{c2::immiscible}} liquids - ANSWER-one of which is uniformly dispersed as droplets
throughout the other ,
{{c1::Sitavig}} is a mucoadhesive buccal tablet for herpes labialis - ANSWER-
{{c1::Wetting}} agents work generally by making suspensoid particles more
{{c2::hydrophilic}} - ANSWER-
{{c2::Nutritive}} sweetener are sweeteners with {{c1::calories}} - ANSWER-
A __________ can be defined as a potent powdered drug mixed with a suitable diluent.
- ANSWER-trituration
A {{c1::dispersed}} phase system is a {{c2::heterogeneous}} system where the
{{c3::internal}} phase is suspended in a continuous (external) phase - ANSWER-
A {{c1::thixotropic}} liquid is a plastic (or pseudoplastic) liquid that - ANSWER-when left
standing, is a restrictive network of interacting solutes, The interacting solutes create
"structure" in the suspension. The liquid thins when stress is applied (e.g., by shaking),
the the structure slowly returns when stress is removed
A capsule diluent with this property can draw in GI fluids, thereby increasing dispersion
and thus dissolution rate : - ANSWER-Hydrophilicity
A friabilator is used to assess the ________ of the tablet - ANSWER-Durability
A tablet hardness tester measures : - ANSWER-crushing strength
Among forces affecting interactions of suspensoid crystals are electrostatic
{{c1::repulsive}} forces and Van der Waals {{c2::attractive}} forces - ANSWER-
Among the advantages of oral solutions are _________ drug availability - ANSWER-
immediate
Among the differences of the properties of different polysaccharide suspending agents
are rheological properties - ANSWER-{{c1::charge}}, {{c2::solubility}}, and
{{c3::viscosity}} grades,
Among the natural polysaccharides used as suspending agents is the very commonly
used biosynthetic polymer {{c1::xanthan}} gum - ANSWER-
, As {{c2::wetting}} agents - ANSWER-solvents penetrate the loose agglomerates of
powder displacing the {{c1::air}},
As depicted on total potential energy of interaction curve - ANSWER-suspensoid
crystals may aggregate very {{c2::strongly}} at close distances at the {{c1::primary
minimum}},
As depicted on total potential energy of interaction curve - ANSWER-suspensoid
crystals may aggregate weakly at the {{c1::secondary}} minimum ,
As particles in a suspension become {{c1::smaller}} - ANSWER-total interfacial surface
area in the system increases, and as a consequence, so does interfacial {{c2::free
energy}},
As suppository bases, PEGs can be hygroscopic, causing them to potentially absorb
rectal water, leading to a : - ANSWER-localized epithelial dehydration, which can lead to
lead to diarrhea or gas,
As we age the number of taste buds _______ - ANSWER-decreases
As wetting agents - ANSWER-polymers can coat the hydrophobic particles with a
multimolecular layer, imparting a {{c1::hydrophilic}} character to the particles,

Binders help hold the : - ANSWER-granule components and tablet together.
Bioavailability from buccal and SL drug delivery can be difficult to predict - ANSWER-
because of anatomical {{c2::variations}} and some of the drug will be {{c1::swallowed}},
Buccal and sublingual membranes are {{c1::not}} keratinized - ANSWER-
Buccal epithelium is {{c1::thicker}} than sublingual epithelium - ANSWER-
Can be defined as successive equal volume additions of diluent to a concentrate with
thorough mixing between each addition : - ANSWER-geometric dilution
Communition is the process of : - ANSWER-particle size reduction
Compared to normal emulsions - ANSWER-microemulsions are thermodynamically
{{c1::stable}},
Compressing tablets directly from powdered material without modifying their physical
nature is called - ANSWER-Direct compression
