CAPSULES Flashcards
are solid dosage forms in which the medicinal agents and/or inert substances are enclosed in a small gelatin shell
CAPSULES
TWO TYPES OF CAPSULES
HARD GELATIN
SOFT GELATIN
used by community pharmacist in extemporaneous compounding of prescription
HARD GELATIN
commonly employed in clinical drug trials to compare investigational drug to another drug or a placebo
HARD GELATIN CAPSULES
Hard gelatin capsule consist of how many pieces of cylinders closed at one end
2 pcs
the shorter piece of a hard gelatin capsule
CAP
the cap of a capsule fits over the open end of longer piece called
BODY
added to make hard gelatin capsule opaque
TITANIUM DIOXIDE
components of capsule shell

gelatin
sugar
water
clear, colorless and essentially tasteless
empty capsule shells
colorant added to capsule shell
FD&C and D&C dyes
- partial hydrolysis of collagen obtained from the skin, white connective tissue, and bones of animals
- stable in air when dry, if moist - microbial decomposition
GELATIN
hard gelatin capsule contains ____ moisture
in %
13-16%
vegetarian capsules are made up of
HYDROXYPROPYL METHYLCELLULOSE
if the capsule is placed in an environement of ____ and additional moisture is absorbed, it will be distorted and lose their rigid shape
HIGH HUMIDITY
if the capsule is placed in an environement of ____ , moisture present in the gelatin capsule is lost, it wil become brittle and crumble
EXTREME DRYNESS
added to protect product from moisture
DESSICANT
TYPES OF DESSICANT
3
dried silica gel
clay

5
biggest capsule size for human
000
commonly used capsule size in veterinary
000
produce the proper capsule fill volume
examples: lactose, microcystalline cellulose and starch
DILUENT / FILLER
assist break-up and distribution of the capsule contents in the stomach
examples: pregelatinized starch, croscarmellose, sodium starch glycolate
DISINTEGRANTS
improve flow properties of powder mixture
examples: talc, magnesium stearate, calcium stearate, stearic acid
LUBRICANTS / GLIDANTS
example of diluent / filler
LACTOSE
example of lubricants / glidants
MAGNESIUM STEARATE
facilitates wetting of powder by the GI fluids
example: sodium lauryl sulfate
SURFACE ACTIVE INGREDIENTS
example of surface active ingredients
SODIUM LAURYL SULFATE
used to polish or clean the capsule shell
GAUZE / CLOTH
adde to make the soft gelatin capsule elastic or plastic like
SORBITOL
soft gelatin capsule contain more moisture than hard gelatin capsule, thus, contains preservatives like
2
METHYLPARABEN
PROPYLPARABEN
why there is a preparation like capsule in a capsule or tablet in a capsule
to separate chemically incompatible agents or to add premeasured amounts of potent drug substances
oldest commercial process that uses set of molds to form capsules
PLATE PROCESS
- a continuous process
- two plasticized gelatin ribbons are continuously and simultaneously fed with liquid or paste fill between the rollers of the rotary die mechanism
ROTATING DIE PROCESS
the gelatin ribbons are fed between a set of vertical dies that continually open and close to form rows of packets in gelatin ribbons
RECIPROCATING DIE PROCESS
packaging for dispensing single dose capsule
UNIT DOSE PACKAGING
packaging for dispensing multiple dose capsule
multiple dose packaging
capsule shell that are not easily tampered and protected from premature opening due to indentations
CONI-SNAP
not suitable for filling into capsules because they absorb water present in a capsule shell that makes the shell very brittle and ultimately lead to crumble into pieces

PLACEBO
latin name of capsule & its meaning
CAPSULA
small container
two piece capsules are commonly referred to as
hard shell capsules
one piece capsules are commonly referred to as
soft shell capsules
- these capsules are cellulose-based
- not made from animal by-products
- no known potential health risks
- consists of hydroxypropyl methylcellulose & water
- no preservatives
- fast dissolving and easily digestible
vegetarian capsule
gelatin is soluble in
hot water & warm gastric fluid
- a noninvasive procedure that entails the use of a gamma ray-emitting radiotracer incorporated into the formulation with a gamma camera coupled to a data recording system
- track the passage of capsules and tablets through the gastrointestinal tract to map their transit time and drug-release patterns

an example of a lubricant/glidant that is waterproof
MAGNESIUM STEARATE
on an industrial scale, ____ designed for modified-release drug delivery are also commonly placed in capsule shells
COATED PELLETS
these liquids that do not interfere with the stability of gelatin shells that may be placed in locking gelatin capsules to ensure retetntion of the liquid
FIXED OR VOLATILE OILS
unsuitable for aqeuous liquids because water softens it and then it will become distorted
GELATIN
