It is process of “Establishing documentary evidence that provide a high degree of assurance that a specific process will consistently produce a product meeting its predetermined specifications and quality attributes”.
In the pharmaceutical industry, it is very important that in addition to final testing and compliance of products, it is also assured that the process will consistently produce the expected results.
Validation is action of proving in accordance with the principles of good manufacturing practices, that any procedure, process, equipment, material, activity or system actually leads to expected results.
Cleaning validation is documented evidence with a high degree assurance that one can consistently clean a system or a piece of equipment to predetermined and acceptable limits.
The primary regulatory concern driving the need for cleaning validation is cross contamination of the desired drug substance either by other API from previous batch runs or by residues from the cleaning agents used.
The prime purpose of validating a cleaning process is to ensure compliance with federal and other standard regulations
1. Cross contamination with active ingredients
Contamination of one batch of product with significant levels of residual active ingredients from previous batch cannot be tolerated.
In addition to the obvious problems posed by subjecting consumers or patients to unintended contaminants, potential clinically significant synergistic interactions between pharmacologically active chemicals are a real concern.
2. Contamination with unintended materials or compounds
While inert ingredients used in drug products are generally recognized as safe for human consumption, the routine use, maintenance and cleaning of equipment's provide the potential contamination with such items as equipment parts, lubricants and chemical cleaning agents3. Microbiological contamination
Maintenance , cleaning and storage conditions may provide adventitious microorganisms with the opportunity to proliferate within the processing equipment.

Review of pharmaceutical product, packaging and ichDeepak Shukla
Review of stability of packaged material like containers and closures.
The whole ppt is regarding the test perform to know the stability of a container which is used for product storage.
It also contain the guidelines of ICH.
stability The ability of a pharmaceutical product to retain its chemical, physical, microbiological and biopharmaceutical properties within specified limits throughout its shelf-life.Why is stability of a drug important?
Drug stability affects the safety and efficacy of the drug product; degradation impurities may cause a loss of efficacy and generate possible adverse effects. Therefore, achieving the chemical and physical stability of drugs is essential to ensure their quality and safety.Common factors that affect this stability include temperature, light, pH, oxidation and enzymatic degradation. Special considerations are also required when dealing with chiral molecules, deuterated internal standards and large biomolecules.

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

2. INTRODUCTION
STABILITY THEORITICAL CONSIDERATION
FACTORS AFFECTING STABILITY
OBJECTIVE
TYPES OF STABILITY
REGULATORY REQIREMENTS
ICH GUIDELINES FOR BIOLOGICAL AND
BIOTECNOLOGICAL PRODUCTS
1 2
3. Drug stability refers to the capacity of a drug substance or
product to remain within established specification of identity,
strength, quality and purity in specified period of time.
Stability is officially defined as the time lapse during which
the drug product retains the same properties and characteristics
that it possessed at the time of manufacture.
The stability of a product is expressed as the expiry period or
technically as shelf life.
1 3
4. It is defined as the time required for the concentration of the
reactant to reduce to 90% of its initial concentration .
It is represented as t90 and the units of time/sec.
t90 = (a-0.9a)/kο
Where, a = initial concentration
kο = specific rate constant for zero order reaction.
The time from the date of manufacture and packaging of the
formulation until its chemical or therapeutic activity is
maintained to a predetermined level of labelled potency and,
its physical characteristic have not changed appreciably or
deleteriously.
1 4
5. The primary factors effecting stability:
pH, temperature, moisture, humidity, light, storage,
closure, containers and oxygen.
The major factors affecting drug stability are;
particle size (suspension and emulsion), pH, additives,
and molecular binding, and diffusion of drugs and
excipients.
1 5
6. To determine maximum expiration date/ shelf life
To provide better storage condition.
To determine the packaging components
To gather information during pre formulation stage to
produce a stable product.
1 6
8. Accelerated stability testing
Long term testing
Stress testing
Photo stability study
1 8
9. Four climate zones can be distinguished for the
purpose of worldwide stability testing as follows :
1 9
ZONE TYPE OF CLIMATE
ZONE I Temperate zone
ZONE II Subtropical zone
ZONE III Hot and dry zone
ZONE IV Hot humid tropical zone
10. International conference harmonization (ICH)
World Health Organisation (WHO)
US Food and Drug Administration (FDA)
European Medicine Agency
1 10
11. Q1A(R2) – Stability testing of new drug substances and
products.
Q1B – Photo stability Testing of new drug substance
and products.
Q1C – Stability testing for new dosage forms.
Q1D – Bracketing and matrixing design for stability of
new drug substance and products.
1 11
12. Q1E – Evaluation of stability data
Q1F – Stability data package for registration.
Application in climatic zones III and IV.
Q5C- Stability testing of biotechnological /biological
products.
1 12
14. In ICH guideline, stability testing of new drugs and
products applies in general to biotechnological and
biological products.
Despite, an extra consideration has to be taken since
these products have distinguishing properties over the
storage period of time.
The products includes bio-molecules, proteins,
polypeptides which needs specific testing for the
stability consideration.
1 14
15. The guidance in the annex applies to well
characteristics proteins, polypeptides, their derivatives
and products of which they are the components and
which are isolated from tissues, body fluids, cell culture
or produced using rDNA technology.
1 15
16. Thus, the documents covers the generation and submission
of stability data for products such as cytokines (interferon,
interleukins, colony stimulating factor, tumor necrosis
factors), erythropoietin, plasminogen activators, blood
plasma factors, growth hormone and growth factors,
insulin, monoclonal antibodies, vaccines consisting of well
characterized proteins and polypeptides.
1 16
17. The reader are referred to the glossary in the ICH harmonized
tripartite guideline for stability testing of new drugs and
products.
However, manufacturer sometimes use traditional terminology,
terms as specified in the parenthesis to assist the reader.
A supplement glossary is also included that explains certain
terms used in the production of biotechnological /biological
products.
1 17
18. 4.1. DRUG SUBSTANCE(BULK MATERIAL)
A bulk material after the manufacture has to be stored
however prior to formulation and manufacture.
Stability data should be provided on at least 3 batches for
which manufacture and storage are representative of the
manufacturing scale of production.
A minimum of six months stability data at the time of
submission should be submitted in cases where storage
periods are greater than 6 months are requested.
1 18
19. For a drug substance with storage periods of less than 6
months minimum amount of stability data in the initial
submission should be determined on case by case basis.
Data from pilot plant scale batches of drug substance
produced at a reduced scale of fermentation and purification
may be provided at the time the dossier is submitted to
regulatory agencies with the commitment to place the 1st
three manufacturing scale batches into the long stability
program.
1 19
20. During manufacture of biotechnological/ bioligical products, the
quality and control of intermediates may be critical to the
production of the final product.
In general, manufacturer should identify intermediates and
generate in house data and process limits that assures their
stability within the bounds of the developed process. While the
pilot plant scale data is permissible, the manufacturer establish
the suitability of such data using manufacturing scale process.
1 20
21. Stability information should be provided on at
least 3 batches of final container product
representative of that which will be used in
manufacturing scale.
A minimum of six months data at the time of
submission should be submitted in cases when
storage periods greater than six months are
requested.
1 21
22. For drug products with storage periods less than 6 months,
the minimum amount of stability data in the initial should
be determined in a case by case studies.
Product expiration dating will be based upon the actual data
the actual data submitted in support of the application.
The quality of the final container product placed on stability
studies should be representative of the quality of material
used in preclinical and clinical studies.
1 22
23. Where one product is distributed in batches differing in
fill volumes ( eg ; 1 ml, 2 ml, 10 ml), unitage 10 units,
20 units, or 50 units) or mass ( eg ; 1 mg, 2 mg, 5 mg)
samples to be entered into the suitability program may
be selected on the basis of a matrix system and /or by
bracketing.
1 23
24. On the whole, there is no single stability – indicating assay or
parameter that profiles the stability characteristics of a
biotechnological/biological products.
Consequently, the manufacturer should propose a stability
indicating profile that provides assurance that changes in the
identity, purity, and potency of the product will be detected.
At the time of submission applicants should have validated the
method that comprise the stability indicating profile and the data
should be available for the review.
1 24
25. The dossier accompanying the application for
marketing authorization should include a detailed
protocol for the assessment for the stability of both
drug substance and drug product.
1 25
26. Potency studies are to be performed at appropriate
intervals as defined in the stability protocol and the
results should be represented in units of biological
activity calibrated, whenever possible, against
nationally and internationally standards.
1 26
27. For the purpose of stability testing of the products described
in the guideline, purity is a relative term.
Due to the effect of glycosylation, deamination or other
heterogeneities, the absolute purity of a
biotechnological/biological product should be typically
assessed by more than one method and the purity value
desired is method dependent.
For the purpose of stability testing, tests for purity should
focus on methods for determination of degradation
products.
1 27
28. 6.1 TEMPERATURE
Since most finished biotechnological/biological
products need precisely defined storage temperatures,
the storage conditions for the real time/real-temperature
stability studies may be confined to the proposed
storage temperature.
1 28
29. Biotechnological/biological products are generally
distributed in containers protecting them against humidity.
Therefore, where it can be demonstrated that the proposed
containers (and conditions of storage) afford sufficient
protection against high and low humidity, stability tests at
different relative humidities can usually be omitted.
Where humidity protecting containers arw not used,
appropriate stability data should be provided.
1 29
30. Studies under accelerated and stress conditions may
provide useful support data for establishing the
expiration date, provide product stability information
for future product development.
1 30
31. Applicants should consult the appropriate
regulatory authorities on a case by case basis
to determine guidance for testing.
6.5 CONTAINER CLOSURE
The interaction of the product and container should not
result into degradation of product. Hence, a proper
consideration has to be undertaken to maintain the
stability of the product.
1 31
32. The shelf lives of biotechnological/biological may vary
days to several years. Thus, it is difficult to draft uniform
guideline regarding the stability study duration and testing
frequency that would be applicable
to all biotechnogical and biological products.
However with few exceptions it is considered 0 tp 5 years.
When self lives of 1 year or less is proposed, the real time
stability studies should be conducted monthly for the first 3
months and at at 3 months intervsn thereafter.
1 32
33. For the product with proposed shelves life more than 1
year, the studies should be conducted every three
months during the first year of storage, every six
months during the second year and thereafter.
1 33
34. Precisely, definite temperture storage are
recommended.
Specific recommendation should be stated, particularly
to those drug products and drug substances that cannot
tolerate freezing.
1 34
