This document discusses labeling, storage, stability, and beyond use dates of pharmaceutical dosage forms. It covers the key information that must be included on labels like the drug name, strength, instructions. Proper storage conditions are outlined for different dosage forms to protect stability based on factors like temperature, light, and moisture. The importance of stability is explained to maintain the drug's therapeutic properties over time. The beyond use date is defined as the last date the patient should use the medication by based on stability considerations.

5. • Label
label means display of printed information which
is securely affixed to the container and primally
packaging containing the medicine.
label should provide the patient with all
necessary information:
» General labeling requirement
» Cautionary and advisory label
» Special instruction for different type of product.
6. Properties of lebel:
• Information given on label should be:
»Accurate
»Legible

7. Importance of label:
• to provide consumers with information on
the label
• to ensure the appropriate and safe use of
approved drug
• To distinguish the product from that of
competitors(establish a brand)

8. Information on the label:
• includes the name and address of supplier
and date of supply
• give precise details as the content of the
container:
» Name of the medicine
» Quantity of the container
» the strength of the medicine: represents the amount of
active ingredient in each dosage unit(/tab,/cap,/ml)
» Units: as a whole number unit, example:100mg rather
than 0.1g
» Batch identification and
» dilute product: indicate the degree of dilution.
9. • state the storage conditions and shelf life of
the product

17. DEFINITIONS : -
DOSAGE FORM:
• Completed form of the pharmaceutical preparation
in which prescribed doses of medication are
included. Examples: Tablets, Liniments, Ointments,
Powders ,Lotions etc.
STORAGE:
• It simply means keeping things at a place ,till it is
used ,so as to preserve the same properties.
18. NEED FOR STORAGE OF DOSAGE
FORMS
• If the drug is not properly stored and on exposure to
air, heat, light and microbes results in degradation
,loss of efficacy and even cause toxicity.
• Light can bring about photolytic decomposition due
to exposure to certain wave length of light.
• Air present inside the container may catalyse
oxidative degradation or other chemical changes.
• Moisture effects the stability of moisture sensitive
preparation.
19. Sterile products are required to maintain sterility
implying exclusion of microbes.
Certain drugs on exposure to air undergoes auto-
oxidation and emulsified lipids are sensitive to
attack. So proper storage of drugs is required which
are sensitive to air, light, moisture.
The stability of drug depends on temperature and
pH.
ex:- Ampicillin is stored at low temperatures (2 – 8 c).
Ampicillin in solution is not stable at pH > 7.

23. DIFFERENT CONTAINERS USED FOR
STORAGE
1. WELL CLOSED:-It protects the container from
contamination with extraneous solids under
normal conditions of storage, handling, transport &
prevent unintentional release of the contents.
2. AIR TIGHT :-It gives protection against extraneous
solids, liquids, vapours under normal conditions of
storage, handling, transport. It prevents changes
due to efflorescence, deliquescence, &
evaporation.
24. 3.SECURELY CLOSED:- This is a air tight container
with a means of preventing unintentional
displacement of the closure.
4.HERMETICALLY CLOSED:-It is impervious to air
and other gases under normal conditions of
storage, handling & transport. Ex:- Glass
ampoule sealed by fusion.
25. Liquid oral preparations
a) Intended to be swallowed (elixirs ,emulsions)
-Glass bottles
b) Not intended to be swallowed ( mouth washes , gargles)
- Ribbed oval glass bottles
Semisolid preparations - creams ,jellies ,ointments
-Collapsible metal or plastic tubes
-Glass or plastic pots.
CONTAINERS FOR DIFFERENT
DOSAGE FORMS
26. • Solid unit dose preparations :-
a) Intended to be swallowed or sucked
(Cachets, soft & hard capsules, pills )
b) Intended for use in body cavities
-Glass ,plastics ,aluminium
-plastic ,metal containers
c) powders
1)For oral administration
Bulk powders -Glass & plastic
2) For external use –
Dusting - used in body cavities .
insuffalations -Air tight glass/plastic
container
29. Drug stability
• Drug stability means the ability of pharmaceutical
dosage form to maintain the
physical,chemical,therapeutic and microbial
propertis during the time of storage and usage by
patient.
30. Factors influencing drug stability
• in liquid dosage form:
» ph
»Temperature
»Solvent effect
»Oxygen
»Light
»surfactant
31. • in solid dosage form:
»Moisture
»Excipient
»Temperature
»Light and oxygen
32. In liquid dosage form:
• PH:- ph is the most important parameter
which affect the hydrolysis rate of drugs in
liquid formulation.
• the influence of ph on the degradation rate is:
»Specific acid base catalysis
» different ph rate profile obtained using
different buffer
33. • TEMPERATURE:- increase in temperature
usually causes a very pronounced increase in
hydrolysis rate of drug in solution.
• OXYGEN:-molecular oxygen is involved in
many oxidation particularly drug is likely to be
affected by oxidative breakdown.
• LIGHT:-exposure to ultra violate light is the
most usual cause of photodegradation.
34. • photolabile drugs are usually stored in
container which exclude ultraviolet light.
• SURFACTANT:- the presence of surfactant in
micellar form has a modifying effect on the
hydrolysis of drug.
35. IN SOLID DOSAGE FORM:
• MOISTURE:- water soluble drugs present in a solid
dosage form dissolves in any moisture which has
adsorbed on the solid surface.
• EXCEPIENT:- excipient with particularly high water
contents, affects stability by increasing the water
content of the formulation.
• TEMPERATURE:- the effect of temperature change
on the stability of solid dosage forms can be
complicated for many possible reasons:-
36. • the drug or one of the excipient may melt or
change its polymorphic form as temperature is
increased
• the drug or one of the excipient may contain
loosely bound water which is lost at high
temperature.
37. BEYOND USE DATE
• Beyond use date is the date after which a
product shall not be used. The dispenser shall
place on the label of the prescription
container a suitable beyond use date to limit
the patients use of the article based o any
information supplied by the manufacturer.
• the beyond use date shall not be later than
the expiration date on the manufacturer
container.
38. • For all dosage forms in determining beyond
use date the dispenser shall take in to account
in addition to any other relevant factors:
»Nature of the drug
» container in which it was packed
» storage condition
» length of the therapy
