1. INTRODUCTION:
The concept of validation was first proposed by two
Food and Drug Administration officers, Ted Byers and
Bud Loftus, in the mid 1970’s in order to improve the
quality of pharmaceuticals. Pharmaceutical Process
Validation is the most important and recognized
parameters of CGMPs.
1
The requirement of process
validation appears of the quality system (QS)
regulation. The goal of a quality system is to
consistently produce products that are fit for their
intended use. The process validation is standardization
of the validation documents that must be submitted with
the submission file for marketing authorization.

The
process validation is intended to assist manufacturers in
understanding quality management system(QMS)
requirements concerning process validation and has
general applicability to manufacturing process.

Some Defination of Validation:
According to FDA,
4
Assurance of product quality is derived from careful
and systemic attention to a number of importance
factors, including: selection of quality process through
in-process and end-product testing.
According to US FDA in 1978,

“A validation manufacturing process is one which has
been proved to do what it purpose or is represented to
do. The proof of validation is obtained through the
collection and evaluation of data, preferably, beginning
from the process development phase and continuing the
production phase. Validation necessarily includes
process qualification (the qualification of materials,
equipment, system, building, personnel), but it also
includes the control on the entire process for repeated
batches or runs”.
European Commission - 1991 - Validation - “Act of
proving, in accordance of GMPs that Any” process
actually leads to expected results.
European Commission - 2000 - Validation -
“Documented evidence that the process, operated within
established parameters, can perform effectively and
reproducibly to produce a medicinal product meeting its
predetermined specifications and quality attributes”.

WHO guidelines define validation as Validation is
documented act of proving that any procedure, process,
equipment, material, activity or system actually leads to
the expected results. Validation act of proving, in
accordance of GMPs that any process actually leads to
expected results. Documented evidence that the process,
operated with in established parameters, can perform
effectively reproducibly to produce a medicinal product
meeting its predetermined specifications and quality
attributes.

2.1 Analytical Validation
Analytical validation is the evaluation of product
quality attributes through testing, to demonstrate
reliability is being maintained throughout the product
ABSTRACT:
The article gives an introduction and general overview on process validation of pharmaceutical tablet manufacturing process.
Process Validation is one of the important steps in achieving and maintaining the quality of final product. Process validation
emphasizes the role of statistical tools and analyses, knowledge, detection, and control of variability and thus gives assurance
on consistency of quality product. The validation study provides the accuracy, sensitivity, specificity and reproducibility of the
established and documented test methods employed by the manufacturer. Thus, validation is an essential part of the quality
assurance. This review examines the need for pharmaceutical validation, the various approaches, process and steps to be
monitored during tablet manufacturing process.
Key words: Process Validation, Types, Validation Stages, Guidelines and Process.
