  • There are four types of the process validation.
    • Prospective validation
    • Concurrent validation
    • Retrospective validation
    • Revalidation 
  1. Prospective validation:
  • Prospective Validation shall be carried out on the small scale or R & D batches during development stage.
  • These validations were carried out to identify the processing steps, equipment settings and process timings, which can prove to be critical in overall impact of product quality. All these steps, equipment setting and process timing are evaluated to finalise the setting parameter. Limits of all critical parameters shall put tentatively.
  • This draft form of study can lead towards the finalisation of Batch Manufacturing Record / Batch Packing Record for large scale batches.
  • The prospective validation shall take care of following:
  1. Process description
  2. Investigation summary of critical processing steps
  3. Finished product release specification
  4. Calibration of equipment
  5. Appropriate analytical methods
  6. Proposed in process control with acceptance criteria
  7. Sampling plan
  8. Method for recording and evaluating results and responsibilities. 
  1. Concurrent validation:
    • This validation comprises of determination and evaluation of process parameters applicable from scale up to large scale batches.
  • Process validation for establishing the predetermined limits of all critical parameters by conducting three consecutive commercial or large scale batches.
  • Validation carried out during routine production or products manufacturing for sale.
  • The tests are finalised based on evaluation of the results of these batches. These batches were monitored for stability and quality trends.
  • Matrix approach can be applied to process validation. The matrix approach means that a plan to conduct process validation on different strength of same product, manufactured by the same process and similar type of equipment. e.g. validation on one strength (preferably smallest) as a representative amongst the multiple strength of the same product. This approach should be in accordance with cGMP and should demonstrate that the process is consistent for all the strength. 

Note: The batches will not be dispatched unless and until the analysis of the validation sample is completed. 

  1. Retrospective validation:
  • Historical trending of all critical parameters obtained from analytical results and / or IPQC results observed after testing of physical, chemical and microbiological parameters of product manufactured by same process. To ensure that all the parameters shall be in the limit and in uniform range.
  • Retrospective validation shall done yearly of products or batches manufactured in previous year.
  • Minimum first 20 batches shall consider for retrospective validation. If less than 20 batches were manufactured in one year then batches of previous years were consider for trending.
  1.   Revalidation:
  • Periodic revalidation: This type of revalidation shall be done on periodic basis as per specified frequency. The revalidation shall be governed by the Change Control procedure.
  • Revalidation after any change : All validated equipment, systems, processes, products etc. shall be continuously monitored for any change, to be considered for revalidation of the same. 
  • Revalidation / Requalification [Verification of validation] shall be considered in the case of :
  • Equipment / Instruments / System:

1)  Substitution of existing equipment with a new equipment /instrument/System.

2) Change of site /location of the equipment / instrument / System from qualified existing place to other place.

3) Any major modification in the existing equipment / instrument /System since purchase which can have an adverse effect on the quality and efficacy of the finished product. 

  • Manufacturing Process:

A change in the validated manufacturing process that has an effect on the quality and efficacy of the finished product,  which includes a change in the following :

1) Master formula or manufacturing process.

2) Raw Materials

3) Equipment

4) Batch Size

5) Change in manufacturing site or location.

  1. Cleaning validation: 


·      Validation of the process by which the equipments are cleaned is called as cleaning validation.


  • Cleaning validation is an important mechanism to protect the pharmaceutical products from cross contamination. A pharmaceutical product can be contaminated by previous product residues, traces of cleaning agent, micro-organisms or any foreign particle as borne particles, dust, raw materials etc.
  • This should be performed to provide a documented evidence that the procedure being followed for cleaning of equipment and accessories is effective and removes residues of previous batch / product up to a predetermined acceptance level, using a well defined protocol and acceptance criteria.
  • For equipments which are not product specific, cleaning procedure for such equipment should be able to ensure that it can consistently remove residues to the predetermined level.


  • There are two methods employed for sampling during cleaning validation. These are Rinse and Swab method. Rinse method will be applicable when swabs are not practically possible.
  • Cleaning procedures for products and processes, which are very similar are do not need to be individually validated. Representative of similar range can be selected to justify the validation programme, which addresses the critical issues relating to selected products and processes.
  • A single validation study under consideration of the “worst case” can be carried out on the basis of the maximum strength, potency, solubility and LD50. The cleaning validation can be evaluated,
    1. For highest strength product in multi strength products or all products.
    2. For highest potency product in all products.
    3. For least solubility in common cleaning solvent i.e. Water.

This “worst case” term can also be referred as “bracketing”. And such approach is called as matrix approach.

  • Three cleaning validations exercise shall be performed and shown to be successful in order to prove that the method is validated.
  • The documentation of  cleaning  validation  shall  include  validation protocol, cleaning procedures, sampling plans, surface area calculations, testing procedures and executed record of the cleaning event, a record of the sampling and  testing events and a validation report which contains clear conclusions against acceptance criteria.
  • This validation shall covers sanitation, microbiology as well as removal of external agents like detergents, using sampling techniques capable of detecting and measuring to very low levels wherever applicable.
  • There are two criteria’s for the cleaning validation, one is dose criteria and second is 10 PPM criteria.
  • Validated analytical methods used for cleaning validation shall have sensitivity to detect residues or contaminant of previous product . The detection limit for each analytical method should be sufficiently sensitive to detect the established acceptance level of residues or the contaminant.
  • Equipment surface area calculation:
  1. The product contact surface area for each equipment shall be calculated by theoretically breaking down the equipment in to basic geometric shapes [cylindrical, cubical, cone, rectangle etc.] and then apply to relevant area calculation formulae.
  2. Amount of contaminant, mix from previous product to next product, depend on the common surface area of equipment used for both previous and next product.
