Presentation Transcript

Slide 1:

PROCESS VALIDATION 1 PROCESS VALIDATION Hardik Patel* Chirag Baladhiya , Paresh Desai, Parth Joshi Atmiya Institute Of Pharmacy,rajkot

Slide 2:

AIP PROCESS VALIDATION HARDIK PATEL 2 Contents Introduction Various regulatory requirements of validation When should a process be validated Types of process validation Priority for Process Validation Types of documentation . Process validation of some Pharmaceutical Processes

Slide 3:

AIP PROCESS VALIDATION HARDIK PATEL 3 Why Is Validation Required? Ø It would not be feasible to use the equipments without knowing whether it will produce the product we wanted or not. Ø Efficient use of resources is necessary for the continued success of the industry. The pharmaceutical industries are concerned about validation because of the following reasons. Ø Assurance of quality Ø Cost reduction Ø Government regulation Introduction

Slide 5:

Process Validation Process validation is defined as the collection and evaluation of data, from the process design stage throughout production, which establishes scientific evidence that a process is capable of consistently delivering quality products. The U.S. Food and Drug Administration (FDA) has proposed guidelines with the following definition for process validation: - “Process Validation” is establishing documented evidence which provides a high degree of assurance that a specific process consistently produces a product meeting its predetermined specifications and quality attributes” AIP PROCESS VALIDATION HARDIK PATEL 5

Slide 6:

AIP PROCESS VALIDATION HARDIK PATEL 6 General view of process validation

Slide 7:

AIP PROCESS VALIDATION HARDIK PATEL 7 Qualification Design Qualification (DQ) Defines the functional and operational specification of the instrument, program, or equipment and details the rationale for choosing the supplier. Installation Qualification (IQ) Demonstrates that the process or equipment meets all specifications, is installed correctly, and all required components and documentation needed for continued operation are installed and in place.

Slide 8:

AIP PROCESS VALIDATION HARDIK PATEL 8 Operational Qualification to provide a high degree of assurance that the equipment functions as intended. Component Operational Qualification of which calibration can be considered a large part. System Operational Qualification to determine if the entire system operates as an integrated whole. Process Performance Qualification: This verifies that the system is repeatable and is consistently producing a quality product. Performance Qualification (PQ) Demonstrates that the process or equipment performs as intended in a consistent manner over time. Test with materials like placebo

Slide 9:

AIP PROCESS VALIDATION HARDIK PATEL 9 Examples: Milling Qualification

Slide 10:

AIP PROCESS VALIDATION HARDIK PATEL 10 Examples: Compression Qualification

Slide 11:

AIP PROCESS VALIDATION HARDIK PATEL 11 • After finalizing formula, process, and specifications • Either before or after new drug application (NDA) Approval • Prefer to start during process development phase • More frequently being done before NDA approval/filing When To Validate

Slide 12:

AIP PROCESS VALIDATION HARDIK PATEL 12 Regulatory Requirements For Validation SECTION Deal with 21 CFR Parts 210 and 211. Current Good Manufacturing Practice Regulations for Finished Pharmaceuticals, Section 211.110 Sampling and testing of in-process materials and drug products. 21 CFR Part 820. Current Good Manufacturing Practice Regulations for medical device Section 211.113 Control of Microbiological Contamination.

Slide 13:

AIP PROCESS VALIDATION HARDIK PATEL 13 Types Of Process Validation

Slide 14:

AIP PROCESS VALIDATION HARDIK PATEL 14 A) Prospective validation Also called as premarket validation Carried out prior to distribution of new product or existing product made under a revised manufacturing processes where such revision may affect product specification or quality characteristic B) Concurrent validation Study is carried out under a protocol during a course of normal production. It gives assurance of present batch being studied and offer limited assurance regarding consistency of quality from batch to batch. This may be practical approach under certain circumstances…. When previously validated process is being transferred to a third party contract manufacturer or to another manufacturing site. Where the product is a different strength of a previously validated product with the same ratio of active / inactive ingredients.

Slide 15:

AIP PROCESS VALIDATION HARDIK PATEL 15 C) Retrospective validation Conducted for a product already being marketed, and is based on extensive Historical data accumulated over several lots and over time. Some essential elements of retrospective validation:- Batches manufactured for a defined period Batch size/ strength/ manufacturer/ year Master manufacturing/ packaging documents Current specifications for active materials/ finished products List of process deviations, corrective actions and change to mfg documents Data for stability testing for several batches Trend analysis including those for quality related complaints

Slide 16:

AIP PROCESS VALIDATION HARDIK PATEL 16 All or a portion of validation that is required to be repeated when changes that affect original validation are made. Examples of changes requiring revalidation Changes to product specifications Process parameters Equipment (type, function, location, control system, major repairs) Raw materials Manufacturing materials Packaging material D) Revalidation

Slide 17:

AIP PROCESS VALIDATION HARDIK PATEL 17 Change Control Written procedures should be in place to describe actions to be taken if a change is proposed to a product component, process equipment, process environment, processing site, method of production or testing or any other change that may affect product quality or support system operations. All changes must be formally requested, documented and accepted by the validation team. The likely impact / risk of the change on the product must be assessed and the need for the extent of re-validation should be determined.

Slide 18:

AIP PROCESS VALIDATION HARDIK PATEL 18 Commitment of the company to control all changes to premises, supporting utilities, systems, materials, equipment and processes used in the fabrication/ packaging of pharmaceutical dosage forms is essential to ensure a continued validation status of the systems concerned. .

Slide 19:

AIP PROCESS VALIDATION HARDIK PATEL 19 Priority for Process Validation A. Sterile Products and Their Processes 1. Large-volume parenterals (LVPs) 2. Small-volume parenterals (SVPs) 3. Ophthalmics, other sterile products, and medical devices B. Nonsterile Products and Their Processes 1. Low-dose/high-potency tablets and capsules/transdermal delivery systems (TDDs) 2. Drugs with stability problems 3. Other tablets and capsules 4. Oral liquids, topicals, and diagnostic aids
