5. Procedure
5.1 Purpose:
5.1.1 The purpose of stability study is to evaluate physical, chemical and microbiological
change(s) with time period under the influence of variety of temperature and humidity
to which drug products may be exposed during its shelf life.
5.1.2 To monitor the drug product throughout its shelf life to determine whether it remains
stable within the specification under the labelled storage condition.
5.1.3 To confirm that the drug product is assured for its efficacy and safety in marketed pack
throughout the cycle of warehousing, distribution, storage and use.
5.1.4 To monitor the stability of drug products for change(s) in manufacturing process or
active raw materials or primary packaging materials.
5.1.5 The results of stability studies shall be used in demonstrating that storage conditions,
retest period and expiration date given to products are justified.
5.2 General:
5.2.1 If product is manufactured under generic name or different brand names but the
formulation, strength, manufacturing process and primary packing remain same; the
samples of any one generic or brand name shall be subjected for stability study.
5.2.2 If manufacturing formula of the drug product is same but primary packaging materials
are different, product packed in each packaging shall be kept for stability studies.
5.2.3 The samples kept at different storage conditions shall be withdrawn from these
conditions at the stipulated time interval and analyzed within - 10 days and + 15 days.

5.3.1 Initially first three batches of drug product shall be subjected ("Initially" means the drug
product is subjected for stability for the first time at the location or new product) for
long term and accelerated stability.
5.3.2 Subsequently minimum one batch per year shall be subjected for long-term stability
study.
5.3.3 Subsequent stability studies are required due to various changes in the existing process
or critical equipment.
5.3.4 Stability study shall be carried out up to the shelf life of the drug product. This may be
extended further if necessary for extending the shelf life of the product for 2 to 3
batches. i.e. continue the stability study up to expiry plus 1 year or period up to which
the drug product is stable, whichever is more. During this 1-year or the period up to
which the drug product is stable, (whichever is more) extended period samples shall be
analyzed at 6 months interval.
5.3.5 Pack selected for stability studies shall be the marketed pack.
5.4 Procedure to provide the samples for stability studies to Stability Section:
5.4.1 Officer - Quality Assurance shall collect the stability samples from manufacturing
department during packing operation. Quantity of samples (1000 Tablets per batch for
both conditions. 700 Tablets for long term condition & 300 tablets for accelerated).
5.4.2 Officer- Quality Assurance shall verify the details of samples and sign the “Stability

5.6.2 Analysis at the time of release (Finished Product analysis), is considered as initial or “0”
month analysis and if finished product analysis date and sample charging date differs by
more than one month, 0 month’s analysis shall be done at the time of charging of samples
to stability chamber.
5.6.3 If sufficient stability data for 3 batches are available and product is stable, some
frequencies in the yearly batch samples may not be analyzed. But samples of next
frequency shall be analyzed.
5.6.4 Stability batches, which are kept for various changes, shall be analyzed as per frequency
mentioned in table or as indicated in Validation Protocol.
5.6.5 If it is not possible to analyze the samples at specified storage conditions within the time
interval specified, samples shall be analyzed for that specified condition at next time
interval indicating justification for the same. e.g. If analysis of sample at 30 OC / 75 %
RH at 12 months is not possible within 30 days of time interval, it shall be analyzed at
18 months.
