QUALIFICATION OF UV-VISIBLE SPECTROPHOTOMETER, FTIR, DSC, HPLCAnupriyaNR
Analytical method qualification consists of a simplified evaluation of a subset of validation characteristics with a goal to demonstrate that an analytical method is scientifically sound and suitable for its intended use. In contrast to validation, analytical method qualification is performed without predefined acceptability criteria. Qualification may be performed as a prerequisite to method validation, or when an assay for product knowledge has not yet been established as a test for a critical product quality attribute. Qualification of equipment is pre-requisite for validation of the process in which the equipment is being used. Many types of equipment have measuring devices on them. Calibration of measuring devices is a part of qualification. Calibration of measuring devices is important, as the data is often collected through them. If the data collected is not from measuring devices that have been calibrated, the data cannot be relied upon. Thus the whole validation exercise can be questioned.
WHO Good Manufacturing Practice Requirements
Good Manufacturing Practice is the part of quality assurance that ensures that products are consistently manufactured and controlled to the quality standards appropriate to their intended use.
QUALIFICATION & VALIDATION.Validation is an essential part of GMP, and an element of QA.Critical steps in the process need to be validated.Need for confidence that the product will consistently meet predetermined specifications and attributes.
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.

This workshop examines the approach to Continued Process Verification and demonstrating that your product and process are operating in a state of control and continue to do so over the life of the product. Without any prior coordination, the theme was elaborated by the afternoon speakers once the conference itself was underway. The concept of “step up step down” for adjusting the level of product scrutiny both for process parameters monitoring and for sampling and testing quality attributes was explored and developed.
validation is a technique of validating the final product either starting from the raw material or within the process, its all types cover the methods of validation and sequence in the product development.

Validation.
Validation is establishing documented evidence which provides a high degree of assurances that a specific process or equipment will consistently produce a product or result meeting its predetermined specifications and quality attributes”.
A system must be qualified to operate in a validated process
The results of analytical procedures should be:
— reliable
— accurate
— reproducible
The characteristics that should be considered during validation of analytical methods are:
— specificity
— linearity
— range
— accuracy
— precision
— detection limit
— quantitation limit
— robustness
Qualification and Validation have big Weightage in the Regulatory Compliance and GMP. Qualification and Validation only can guarantee about the Product Safety, Integrity, Strength, Purity and Quality assurance.
Almost all the regulatory bodies are expected to have Risk Based Quality System. Quality Risk and its assessment has tremendous output and benefits towards the Patient Safety.
Pharmaceutical Good Manufacturing PracticesPharmaceutical
When you are in healthcare, Then GMP is must. Regulatory philosophy for product Quality have been changed from "Quality by Testing QbT" to "Quality by Design QbD". Quality is to be built in product and that only can be done by GMP.
To maintain the desired SAL at the plant is task which demands great care and control over Man, Machine & Method. This summarize work will definitely help you as hand note.
Trends changed from Non compliance to RR --> Gap to RR --> Data Integrity --> DIB --> Smart Audit & Smart Data.
RR = Regulatory Requirements
DIB = Data Integrity Breach
Take a serious Note for Data Integrity whether you are small or big organization. Your Data is the Heart of your business. Regulatory bodies are highly conscious about such issues. For beginners in this path, my small note can help you a lot.
It is difficult to maintain the sterility and It is more difficult to investigate when the status is Non sterile. So this ppt narrate the way for you to investigate the Non sterility.
Solvent plays a crucial role in the reaction. So we should smartly work with solvent. This presentation tries to summarizes the role as well as the effects of the solvent on the different reactions.
Quality Assurance is of Tremendous Importance in Pharma and Health care sector.
A brief of that is try to explain here..
A Trust of the Customer on Product is solely based on the Effective QA
In the Pharmaceutical, We can get accurate result of the whole population or Whole Batch only and only if Our Sampling Method is perfect and Accurate.
Sampling is also one of the IMP technique for the Statistical calculations.
In Industry there are lots failures related to the routine process, Equipment and System by one or other means.
So one must analyze control such failures in manner that it will not affect your ultimate output and obviously that is your Product and its Quality.
It is real Art and Talent to make an effective Standard Operating procedure and understanding of the difference between guideline and SOP.
SOP should tell itself
In Pharma and Biotech, Weightage of the Documentation is around 70 % because as per FDA "If you do not have Document, You dint have do it."
So Good Documentation Practice is of tremendous importance for the Industry to comply any regulation like FDA, GMP or ISO.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

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.

4. Validation
“Validation is establishing documented evidence which provides a
high degree of assurance that a specific process or equipment will
consistently produce a product or result meeting its pre-determined
specification and quality attributes .”
Validation is a key process for effective Quality Assurance.
QA is the heart and soul of Quality control
QA = QC + GMP
Quality Control is incomplete without coordination of Production.
Quality Square Industry 4
5. An exercise to create as much paper as possible
Another unnecessarily burdensome regulatory requirement
Quality Square Industry 5
6. Confirmation by examination and provision of objective
evidence that the specified requirements have been
fulfilled.
Quality Square Industry 6
7. To form basis for written procedures for production and process
control which are designed to assure that the drug products have
the identity, strength, quality, and purity they purport or are
represented to possess.
To determine that process consistently performs as intended by
repeatedly running the system on its intended schedules and
reporting all relevant information and data.
Results must demonstrate that the process meets pre-determined
specifications under normal conditions.
Quality Square Industry 7
8. Quality :
- Customer satisfaction : Non-conforming product can lead to lost
customers.
- Customer mandated: Provision for securing good business
Product liability: Conformance to product specifications must be
maintained.
Understanding Equipment, System, Processes :
- Process improvement, technology transfer, related product
validation, rapid failure investigations, increased employee
awareness
Quality Square Industry 8
9. Cost reduction :
- Increased efficiency, shortening lead-time resulting in lower
inventories.
- Fewer rejects and reworks
- Longer equipment life by operating the equipment as per
manufacturer’s specification and establishment of cost effective
preventive maintenance schedules.
- Possible reduced testing of raw materials, bulk formulations and
finished products.
Regulatory requirement
o Successful inspections
o Approved products
o For export
Quality Square Industry 9
12. Prospective Validation
This if performed for all new equipment, products and processes.
It is a proactive approach of documenting the design, specifications
and performances before the system is operational.
This is the most defendable type of validation.
Quality Square Industry 12
13. Concurrent Validation
This if performed in two instances i.e. for existing equipment,
verification of proper installation along with specific operational test
is done.
In case of existing, infrequently made product, data is gathered
from at least three successful trials.
Quality Square Industry 13
14. Retrospective Validation
This is established documented evidence that the process has
performed satisfactorily and consistently over time, based on review
and analysis of historical data.
The source of such data is production and QA/QC records.
Retrospective validation generally not accepted Because…..
The issues to be addressed here are changes to equipment, process,
specification and other relevant changes in the past.
Lack of validation protocols usually indicates a lack of
documentation, and often data is reported as only pass or fail which
does not permit statistical analysis which can only be performed on
numeric data.
Quality Square Industry 14
15. Revalidation
Consider periodic revalidation where cumulative minor changes to
process and raw materials may eventually affect process.
Sterilization processes typically are revalidated periodically (once a
year or as needed).
Quality Square Industry 15
16. Some reasons for revalidation
Change in process that may affect quality or validation status
Negative trend in quality indicators
Change in the product design that affects the process
Process is moved within facility or transferred from one facility to
another
Change in the application of the process
