2. A Container Closure System must be designed to protect the drug
during actual conditions of Storage, Shipment and Use.
 It should be able to deliver the correct amount of product at the time of use.
 It must not interact with the product over its shelf life.
Effort required to develop or select the appropriate Container is based on:
 A Risk Assessment considering the Route of Administration.
 Class of Drug Product.
 Therapeutic Range.
 Chemical and Physical Stability of the drug substance.
 Drug Product Matrix.
 Packaging Component.
 Conditions of Storage and Use.
Introduction

3. Some examples of Actual Events of Interaction between
containers and dosage forms:
Migration of plastic additives to drugs
Migration of preservatives
Migration of drug to plastic or coating glass
Migration of chemicals from heat seals, plastics, and foils
into drugs
Degradation of components from sterilization
Migration of inks, adhesives, and chemicals in paper into
inhalation solutions

4. To determine the appropriate container closure system, one should consider
the following:
 Preformulation information on the drug substance
 The nature of the dosage form
 Drug product information
 Container material qualification (CAS number, 21 CFR qualification, USP
qualification, etc.)
 Container/product compatibility
 Impact of the packaging operation on the drug product
 Ruggedness of the container system under actual conditions of packaging,
shipping, storage and use
 Performance

cations are replaced by boron and/or
aluminum & zinc.
• It is more chemically inert than the
soda-lime glass
• It is used to contain strong acids &
alkalies as well as all types of
solvents.
Type II • They are made of commercial soda-
lime glass that has been de-alkalized
or treated to remove surface alkali.
Type III • Containers are untreated & made up
of commercial soda-lime glass of
average or better-than-average
chemical resistance.
Type NP • Containers made up of soda-lime
glass are supplied for non-parenteral
products, those intended for oral or
topical use.

18.  It is performed to investigate the Physicochemical
interactions that might occur between the product
and package.
 Packaging evaluation is designed to identify,
characterized and monitor interactions to achieve a
safe, unadulterated, stable and efficacious product.
 An Important step – to characterize the materials and
the chemicals that can migrate or extract from
packaging components to the drug product.
Packaging Evaluation

19.  To Establish suitability, Evaluation of Four Attributes is
Required -

29. Leak test:
The plastic containers (non injectables and injectables):
 Fill 10 plastic containers with water and fit the closure.
 Keep them inverted at room temperature for 24
hours.
 No sign of leakage should be there from any
container.
Tests For Plastic Containers

30. Water permeability test:
 Fill 5 containers with nominal volume of water and sealed.
 Weigh each container.
 Allow to stand for 14 days at relative humidity of 60% at 20-
25 degree Celsius.
 Again weigh the container.
 Loss of weight in each container should not be more than
0.2%.
Collapsibility Test:
 This test is applicable to the containers which are to be
squeezed for removing the contents.
 A container by collapsing inward during use, yield at least
90% of its normal contents at the required rate of flow at
ambient temperature.

31. Preparation Of Sample (Solution-A):
 Wash closures in 0.2%w/v of an surface active agents
for 5min.
 Rinse 5 times with distilled water and add 200m1
water and is subjected to autoclave at 119 to 123 °C for
20 to 30m in covering with aluminum foil.
 Cool and separate solution from closure (solution-A).
Tests For Rubber Closures

32. I. Sterility Test:
When treated closures are subjected to sterilization
test at 64-66°C and a pressure of about 0.7 KPa for 24hr.
II. Residue On Evaporation:
50ml of solution A is evaporated to dryness at
105°CThen weigh the residue NMT 4mg.
III. Penetrability:
 This is measured to check the force required to make a
hypodermic needle penetrate easily through the closure.
 It is measured by using the piercing machine.
 The piercing force must not exceed a stated value.
 If it exceeds that stated value, the hypodermic needle can
be damaged as a result of undesirable hardness of the
closures.

33. IV. Fragmentation Test:
For closures for aqueous
preparations
For closures for dry
preparations
Place a vol of water corresponding to
the nominal vol minus 4 ml each of 12
clean vials
Close the vials with the 'prepared'
closures& allow to stand for 16 hours
Close 12 clean
vials with the '
prepared'
closures
Using a hypodermic needle with an external diameter of 0 8 mm inject 1 ml of
water into the vial and remove 1 m I of air
Carty out this operation 4 times with new neede each time

34. V. Self - Sealability Test:
This test is applicable to closures intended to be used with
water.
 Close the vials with the 'Prepared' closures
 For each closure, use a new hypodermic needle with an external
diameter of 0.8 mm & pierce the closure 10 times, each time at a
different site.
 Immerse the vials upright in a 0.1% w/v solution of methylene blue &
reduce the external pressure by 27KPa for 10 min.
 Restore the atmospheric pressure and leave the vials immersed for 30
minutes. Rinse the outside of the vials.
 None of the vials contains any trace of colored solution.
Pass the liquid in the vials through a filter with a pores size of 0.5 um.
