The Grim Reality
• First WHO draft text on good manufacturing practices requested by the Twentieth World Health Assembly (resolution WHA20.34)
• Twenty-first World Health Assembly
• “Draft requirements for good manufacturing practice in the manufacture and
quality control of drugs and pharmaceutical specialties”
1967
WHO Certification Scheme on the Quality of Pharmaceutical (GMP text as an integral part of the Scheme
1969
• revised versions of both the Certification Scheme and the GMP text
1975
includes the following:
veterinary products administered to food-producing animals;
starting materials for use in dosage forms, when they are subject to control
by legislation in both the exporting and importing member country
information on safety and efficacy
CERTIFICATION SCHEME
• Presented in 1992
• Quality management in the drug industry: philosophy and essential elements”, outlines the general concepts of quality assurance as well as the principal components or subsystems of GMP, which are joint responsibilities of top management and of production and quality control management.
• These include:
• hygiene
• validation
• self-inspection
• Personnel
• premises,
• equipment,
• materials and documentation.
REVISED REQUIREMENTS FOR GMP
• Part of QA aimed at ensuring that PRODUCTS are consistently MANUFACTURED and CONTROLLED to the quality standards appropriate to their intended use (WHO, 2007)
GMP/cGMP
• system of QA aimed at ensuring that products are consistently manufactured to a quality appropriate for their intended use and is concerned with both manufacturing and QC processes and procedures (AO 43 s. 1999)
GMP/cGMP
• recognized worldwide for the control and management of manufacturing and quality control testing of foods and pharmaceutical products.
GMP/cGMP
Philippine GMP Regulations
(Adoption of the 1st edition of the Current Good Manufacturing Practice Guidelines by the Bureau of Food and Drugs)
• AO 43 S. 1999
(Adoption and Implementation of the GMP as the standard on the manufacture of pharmaceutical products)
• AO 2012-2008
(Philippine FDA mandated all drug manufacturers to ensure strict and full compliance to the newly adopted GMP)
• FDA MC 2012-004
a. All manufacturing processes are clearly defined, systematically reviewed in the light of experience and shown to be capable of consistently manufacturing medicinal products of the required quality and complying with their specifications;
b. Critical steps of manufacturing processes and significant changes to the process are validated;
Basic Requirements of GMP
• The regulatory process through which industry measures actual performance, compares it with standards, and acts on the difference
• A tool which gives the assurance that a product conforms to standards and specifications through a system of inspection, analysis and action.
• The day to day control of quality within the company
• A department staffed with scientists and technicians responsible for the acceptance and rejection of incoming raw materials and packaging components
• To assure that systems are being controlled and monitored
• For the approval or rejection of completed dosage forms
QUALITY CONTROL
• is a process by which the pharmaceuticals are suitably packed so that they should retain their therapeutic effectiveness from the time of packaging till they are consumed.
Packaging
• may be defined as the art and science which involves preparing articles for transport, storage display and use.
Packaging
is the means of providing protection, presentation, Identification, Information and convenience to encourage compliance with a course of therapy.
• Economic way of protecting, preparing, identifying and containing the drug products
• Labels, containers
Pharmaceutical packaging
Role of packaging
Protection
Presentation
Identification
Information
against light
against reactive gases
against moisture
against microbes
against physical damage
against adulteration
•is the material that first envelops the product and holds it.
• This usually is the smallest unit of distribution or use and is the package which is in direct contact with the contents.
• Immediate container
• Indirect contact with the product
• May be used for administration
e.g. bottles, caps, liner, cottons (coil or filler) silica gel (desiccant), glass, plastic, rubber
Primary packaging
• is out side the primary packaging - used to group primary packages together.
• Outer packaging
• Not always present
e.g. carton boxes, corrugated boxes (also considered as Tertiary
packaging) Labels, inserts
• designates the packaging used to group various pre-packaged products together.
Secondary packaging
•is not in direct contact with the actual product, its use and application usually differ distinctly from those of primary packaging, although the purpose of both type may at times converge.
secondary packaging
Secondary packaging said to have two central functions:
Branding & Display
Logistics
: Secondary packaging plays a vital role in the marketing strategy surrounding the product. This is especially relavent in case of display packaging.
Branding & Display
: secondary packaging serves to group sevaral products together for ease of handling, transport and storage. This means that secondary packaging must be able to :
• Contain relatively large volume of primary packaged product
• Transport the product safely to the retailer or consumer destination
• Keep the primary packaging in its original condtion during storage
Logistics
Different type of Secondary Packaging materials
• Paper and boards
• Cartons
• Corrugated fiberboard
is used for bulk handling, warehouse storage and transport. Most common form is palletized unit load that packs tightly in to containers.
Examples: Brown cardboard boxes, wood pallets
Tertiary packaging
2 COMPONENTS OF PACKAGING:
• Composed of a container and its closure
may be defined as a device in which the drug is enclosed and is in direct contact with the drug.
Container
is a device which seals the container to exclude oxygen, carbon dioxide, moisture, micro-organisms and prevent the loss of volatile substances.It also prevents the loss of medicament during transport and handling.
Closures
• is defined as a object that can be used to hold or transport something.
Container
is a device that hold the pharmaceutical product and it may or may not be in direct contact with it.
• Pharmaceutical container
Types of containers
• Multi dose container
• Air tight container
• Light resistant container
• Aerosol container
• Well closed container
• Single dose container
: is used to protect the preparation from contamination by extraneous solids to prevent the loss of potency of active constituents and to prevent the loss of contents during transport, storage and handling.
Well closed containers
: are used to protect the containers from atmospheric contamination of liquids, solids or vapors. They prevent the drugs due to efflorescence, deliquescence or evaporation.
Air-tight containers
is that which does not allow the air or other gases to pass through it. They are generally used for injectables.
Hermetically sealed container
are used to protect the drugs which undergo decomposition in the presence of light. For e.g .Amber colored glass or opaque glass.
Light resistant containers
They are used to supply only one dose of the medicament. They are sealed in such a way that the contents cannot be removed without removing the seal, the contents so removed are consumed immediately.e,g. ampoules.
• Single dose containers:
should hold a number of doses. It is sealed in such a way that success doses can be withdrawn easily without changing the strength, quality or purity of the remaining contents e.g multi dose vials.
A multi dose container
•Containers for aerosols must be strong enough to withstand the pressure evolved inside the container at the time of use of preparation.
• Only true tamper-resistant packaging
• Cannot change the inside of canister because it is pressurize
Aerosol containers
• are devices and techniques used to close or seal container such as a bottle, jug, jar, tube, can etc.
• can be a cap, cover, lid, plug, etc.
Closures
Types of closure
Screw top
Snap on
Spray bottle
Crown cap
Child resistant
Friction fit
is a mechanical device which is screwed on and off of a threaded “finish” on a container.
• Either continuous threads or lugs are used.
• Metal caps can be either preformed or in some instances, rolled on after application.
• Plastic caps may use several types of molded polymer.
Screw top
•Beverage bottles are frequently closed with crown beverage caps.
These are shallow metal caps that are crimped into locking position around the
Crown cap
Some closures snap on. For opening, the top is designed to pry off or, break off, or have a built in dispenser.
Snap on
is a bottle that can dispense, squirt, spray or mist fluids.
A common use for spray bottles is dispensing cool cleaners, cosmetics, and chemical specialties.
Spray bottle
A spray bottle
– Difficult for children under 5 years of age to open
Instruction:
• Press down first, and turn open
• Squeeze and turn
• Align the arrows
• Latch top – thumb and flip open
Child resistant
has special closures designed to reduce the risk of children ingesting dangerous items.
• This is often accomplished by the use of a special safety cap.
• It is required by regulation for prescription drugs, over-the-counter medications, pesticides, and household chemicals.
• Child-resistant packaging
• Some containers have a loose lid for a closure.
• Laboratory glassware often has ground glass joints that allow the pieces to be fitted together easily.
• An Interference fit or friction fit requires some force to close and open, providing additional security.
• Paint cans often have a friction fit plug.
Friction fit
• Resistance to tampering is required for some types of products. Container closures can be one of several layers of packaging to deter tampering and to provide evidence of attempts at tampering. Sometimes tamper resistance is obtained by or integral with the closure.
• Uses an indicator which if breached or missing can provide evidence that tampering is occurred

TYPES OF INJECTION CONTAINERS
SINGLE DOSE
MULTI DOSE
Each dose is in a separate container from which it is given to the patient with a syringe. Usual volumes are from 0.5-10mL. They may be packed in ampoules, cartridges or injection units.
SINGLE DOSE INJECTIONS OF SMALL VOLUMES
SINGLE DOSE INJECTIONS OF SMALL VOLUMES
AMPOULES CARTRIDGES INJECTION UNITS
• Most common
• Made entirely of glass in a size
range of 0.5-50mL.
• Glass may be neutral or lime soda but former is preferred.
• Can be used only once and consequently need not be very strong.
• Their walls can be thin with the advantages of lightness, greater thermal resistance and more rapid heat conduction to the contents during sterilisation.
• After filling, ampoules are sealed by fusion of glass, so there is no danger of entry of microorganisms.
• Plastic ampoules have not been extensively used.
Ampoules
• Cylindrical glass tubes with a capacity of slightly more than 1mL.
• They are closed at one end with a rubber stopper and the other end by a rubber plunger.
• Compared with ampoules, they are quicker and easier to use. They are safer as accidental contact with potent drug preparations in the injection is minimised as well as there is no possibility of injecting glass spicules.
• More suitable for suspensions.
• Syringe is unbreakable and only the needle mount need to be sterilised (only part touched by the injection).
• Major disadvantages are use of rubber and the need for special syringe.
Cartridges
• Disposable injection units combining container and syringe which eliminates the need to transport sterile syringes or facilities for sterilisation.
• Early development was a soft metal tube with a needle attached. It has two major disadvantages viz-a-viz contents are invisible and it is necessary to guard against the solution corroding the container as well as container affecting the solution.
• Automatic injector was developed which is packed in a neutral glass ampoule containing an inert gas under pressure. Advantage is that the user has nothing to sterilise or assemble, therefore time saved and safety are even greater.
• Plastic syringes consists of the injection in small plastic syringe. The absence of gas is an advantage but the contents are not clearly visible. Care must be taken not to squeeze it after the cap has been removed because the barrel is not rigid. Its use is limited because of various
Imjection Units
Infusion fluids usually given IV, are slowly dripped into the patient’s body and 3-4L may be given in 24 hours. Containers must be large and strong enough to withstand frequent cleaning, sterilisation, transport and handling. Bactericides are not permitted in large volume intravenous injections, therefore infusion fluids must always be regarded as single dose injections.
