PHARMACEUTICAL PACKAGING.
·
Definition—
Pharmaceutical packaging is the phenomena or operation, as the part of any drug discovery
and development program.
Pharmaceutical products generally
require a standard
of packaging which is superior to that of most other
products in order to support and comply with their main requirements, i.e. proven efficacy,
safety, uniformity, reproducibility, integrity, purity with limited impurities, minimum side-effects coupled to minimum product liability risks,
and a good shelf-life stability profile.
·
For any packaging require a
discipline and lots of knowledge about the drugs formulations and dosages form, and the general physical
and chemical properties of
drug substances. Packaging helps in the products stability, transportation, storage,
and deterioration conditions.
·
Pharmaceutical packaging
of the economical means providing
protection identification information, convenience and stability
of the product.
Pharmaceutical packaging refers to the process of enclosing pharmaceutical products in containers to protect them from external influences, maintain their integrity, and ensure their safe and effective use. It plays a critical role in preserving the quality, stability, and efficacy of medications. Here's a brief overview of pharmaceutical packaging:
1. Purpose and Importance: Pharmaceutical packaging serves multiple purposes, including:
- Protecting the product from physical damage, moisture, light, and air.
- Preventing contamination or tampering.
- Extending the shelf life and stability of the medication.
- Providing essential information and instructions for safe use.
- Enhancing patient compliance and convenience.
2. Packaging Materials: Pharmaceutical packaging employs a variety of materials based on their suitability for specific products and requirements. Common packaging materials include:
- Plastic: such as high-density polyethylene (HDPE), polypropylene (PP), and polyethylene terephthalate (PET).
- Glass: for vials, ampoules, and bottles.
- Aluminum: for blister packs and foil pouches.
- Paperboard and cartons: for secondary packaging.
- Labels and inserts: for product information, dosage instructions, and warnings.
3. Types of Pharmaceutical Packaging:
- Primary Packaging: The immediate container that comes into direct contact with the product, such as bottles, vials, blister packs, ampoules, and syringes.
- Secondary Packaging: The outer packaging that contains primary packages, such as cartons, boxes, or tamper-evident seals.
- Tertiary Packaging: The packaging used for shipping and transportation purposes, such as pallets and shipping containers.
4. Safety and Compliance: Pharmaceutical packaging must meet strict regulatory standards and guidelines to ensure patient safety and product quality. These regulations govern aspects such as child-resistant packaging, tamper-evidence features, labeling requirements, and stability testing.
5. Innovations in Pharmaceutical Packaging:

- Temperature-Controlled Packaging: For transporting and storing temperature-sensitive medications, utilizing insulated containers or refrigerated packaging.
- Anti-Counterfeiting Measures: Implementing security features like holograms, barcodes, and unique identification codes to combat counterfeit drugs.
6. Patient-Centric Packaging: Packaging design considerations focus on enhancing patient convenience, usability, and adherence. Features include easy-to-open containers, clear instructions, large font sizes, and patient-friendly dosing devices.
Pharmaceutical packaging is a critical aspect of the drug manufacturing and distribution process. It ensures product integrity, protects patient safety, and facilitates effective medication use. Ongoing advancements in packaging technologies aim to improve patient outcomes, enhance product security, and streamline pharmaceutical supply chains.
o Factor affecting pharmaceutical packaging—
· The type of dosage
form
· The route or mode of administration or use
· The type of pack (Blister or strip)
· The mode of sale/marketing area
· The mode of dispensing via a combined
device/pack.
o Types of packaging testing—
o
Drop test.
o
Collapsibility test.
o
Vibration test.
o
Shock test.
o
Inclined impact test.
o
Revolving drum test.
·
Ideal characteristic of packaging—
o Provide the high degree
of protection against
any contamination like environment
as well as artificial issues.
o Do not show any incompatibity (physical or chemical) with the product material.
o Easy to handling, storage and transport
according to the customer convenience.
o Easy to sterilization method and easily
participate in recycling
process.
o
Show more longevity and high printing
property.
o
Affordable economical value.
o Types of packaging—
·
Primary packaging— In primary packaging
material are directly
covered the products and come close to
the products and hold
it. It provides the initial safety
barrier for product. This type of packaging is
often intended for the end user or consumer so it is also called
consumer unit packaging. Example:- Strips, Blister,
bottle, spray cane.
·
Secondary packaging— These types of packaging apply, outside of the
primary packaging and it facilitates the handling of
smaller products by combining them into a single
pack. Example:- Boxes.
·
Tertiary packaging— It is used for bulk handling and shipping. It facilitates
the handling, storage and transport of goods. It provides the final barrier to products from damage.
o Types of packaging materials—
o
Glass material.
o
Plastic material.
o
Metals materials.
o
Rubber materials.
o
Paper board materials
§ Glass packaging.
·
Definition—
Neutral glass is a borosilicate glass containing significant amounts of boric oxide, aluminium oxide,
and alkali or alkaline earth oxides. It has a high hydrolytic resistance and a high thermal
shock resistance.
o Glass has been widely used as packaging materials
and it is moulded in any shape, size, and thickness. Most of parenteral preparation are used the glass materials.
·
On the basis of hydrolytic resistance it divides
into three parts.
·
Type I glass containers which are of neutral glass, with a high hydrolytic resistance, suitable for most
preparations, not for parenteral use.
·
Type
II glass containers which are usually of
soda-limesilica glass with high hydrolytic resistance are suitable
for most acidic and neutral,
aqueous preparations, not for parenteral use.
·
Type
III glass containers which are usually of sodalime-
silica glass with only moderate
hydrolytic resistance. They are generally suitable for non-aqueous preparations for parenteral use.
o Advantages of glass packaging—
o They are transparent or uncolored packaging
to permit the visual inspection of the products
contents.
o
They have a good protection for powder because
powder very sensitive against the moisture and temperature.
o
Available in variety
of shape and size according to our needs.
o Colored glass (amber colored) is also used in the packaging
for the more sensitive materials.
·
Disadvantage of glass
packaging—
o
High risk during the transport and handling because it is fragile in nature.
o
Glass is heavy
in weight than other.
·
High risk of product contamination
due to broken glass piece and some time release
alkali to aqueous preparation
§ Plastic packaging.
·
Definition— Plastic packaging
for pharmaceutical products
is made from plastics based on
the following polymers: polyethylene (low or high density), polypropylene, and polyvinyl chloride,
polystyrene and to
a lesser extent polyethylene terephthalate. The
containers consist of one or more polymers together with certain additives if necessary. They should be manufactured from materials that do not include in their composition any substances that can be
extracted by any contents in such
quantities so as to alter the efficacy or stability of the product or to present a toxic hazard. Additives may
consist of antioxidants, lubricants, plasticizers
and impact modifiers but not antistatic agents and mould release agents.
o Advantages of plastic
packaging—
o
It is flexible
in nature so it cannot easily breakable.
o Due to less weight than the glass it is easy to transport
and handling.
o Verity of shape and size are available according
to our convenience.
o The high versatility of plastic allows for ease of reuse and recycling. In fact, these days’ companies
are creating specialized plastic bag making
·
machines that help you optimize
on the recyclability of plastic.
o The durability offered by plastic
packaging also allows manufacturers
to print eye-catching, high-quality custom designs, and thereby increase
product visibility in a retail
setting.
o Disadvantage of plastic
packaging—
o
Plastics are highly
sensitive for light so it is easily effects by heat
o It is easily reacts with the products materials
and alters the products physical and chemical properties.
o
It is not easily degrades by the
nature, so it shows harmful impacts on the environment and health.
o
Plastics show the poor longevity and poor printing.
· Metal packaging.
·
Definition—
Metal is one of the
way for packaging of most hazards
substances the metals commonly used for this purpose are aluminium foil, tin plated , steel, lead etc. Metals
are used in most of the collapsible tubes packaging.
o The common expression used to describe
such a process is “canning”. Canned food has become an important part of the human diet in developed
countries during the past
century.
o
Advantages of metal packaging—
o Metal
covering is impermeable for the light, moisture and gases so it provide high degree of protection against
the environment issue.
o Due
to hardness of metal it is not easily breakable, and easy in transports and handling.
o
They are light in weight
compared to glass containers.
o
Attractive labels are easily printed
on the surface of metals.
·
Disadvantage of metal packaging—
o
They show high economical value.
o
Due to heavy weight it is easy in transport.
o
Some metals are reacts to the products and cause poisoning
conditions.
o
Rusting is cause in some metals by absorbing the moisture.
· Rubber packaging.
·
Definition— Rubber is used mainly for the construction of closure meant for vials, transfusion fluid bottles, dropping
bottles and as washers
in many other types of product. The main types of rubber used for pharmaceutical products include
natural rubber, neoprene, nitrile, butyl chlorobutyl, bromobutyl and silicone.
·
Silicone is the most expensive and
although the most inert, is readily permeable to moisture, gases and absorbent
to certain preservative.Advantages of rubber packaging—
o
Water absorption is very low, so it provides
the better resistance against the moisture
and humidity.
o
Due to stretchable nature, it is easy to handling and transport.
o It is the cheaper
materials than metal and glass.
It shows good economical
value.
o
Most of the rubber materials are used for the closing
apparatus and provide
the addition protection against any contamination.
o
Nitrile rubber is heat resistant and oil resistant
due to presence of nitrile group.
·
Disadvantage of rubber packaging—
o
Absorption of bactericide and leaching of extractives are
considerable.
o It does not perform well when exposed to the chemicals substances.
o
It is very expensive.
·
Some time rubber materials
also reacts the products material
and alters the products physical and chemical properties.
