 Principle

The objective of the cleaning validation is to verify the effectiveness of the cleaning procedure for removal of API residues, degradation products, preservatives, excipients, and/or cleaning agents as well as the control of potential microbial Contaminants. In addition one need to ensure there is no risk associated with cross-Contamination of active ingredients

Objective

This document on Cleaning Validation aims to address special considerations and issues pertaining to validation of cleaning procedures for Filling & sealing Machine (Dry Suspension) used in the manufacture of pharmaceutical products. The document is also intended to establish inspection consistency and uniformity with respect to equipment cleaning procedures.

Scope

The document is intended to cover cleaning Validation of Filling & sealing Machine (Dry Suspension) for the removal of contaminants associated with previous products, residues of cleaning agents as well as the control of potential microbial contaminants

Sampling Procedure

There are two general types of sampling that are considered to be acceptable, direct surface sampling (swab method) and indirect sampling (use of rinse solutions). A combination of the two methods is generally the most desirable;

However the Rinse sample technique will be applied for sampling according to following plan:

Direct Surface Sampling (Swab Method)

Area difficult to clean and which are reasonably clean can be evaluated by direct surface sampling method (Swab Method), leading to establish a level of contamination or residue per given area i.e. 60 – 100 in2. The residue that are dried out or are insoluble can be sampled by Swab Method.

The suitability of the method to be used for sampling and of sampling medium should be determined. The ability to recover the sample accurately may be affected by the choice of sampling method. It is important to assure the sampling medium and solvent (used for extraction from the medium) are satisfactory and can be readily used. 

For determination of the Microbiological Contamination on surfaces is to use sterile cotton swabs moistened with sterile peptone water, WFI, or Phosphate Buffer. Using sterile forceps and aseptic technique, an area of predetermined size, e.g. 60 - 100 in2, is wiped with a sterile swab. The swab is then aseptically transferred to a sterile tube containing a suitable diluent. The tube is then agitated to suspend any viable microorganisms and aliquots are placed in a semisolid medium to obtain quantitative results.

Passive Air Sampling (Settle Plate Method)

A sterile 60-mm Petri Dish containing a semi solid medium nutrient agar with a convex surface is pressed directly onto the previously decontaminated surface to be settled.

The medium is then incubated for a predetermined period and the plate is examined for the evidence growth. The contamination is reported in term of Colony Forming Units (CFU) per plate. The plate is of standard size and the assumption is made that any contamination is uniformly distributed, the results can be extrapolated to determine the residual bio burden on the entire surface.     

Rinse Sampling

Rinse samples allow sampling of large surface area and of inaccessible system or parts that cannot be routinely disassembled. However consideration should be given to the fact that the residue or contaminant may be soluble or may be physically occluded (Hidden somewhere) in the machine.

Placebo

Placebo sampling method provide the best simulation of the actual production of the subsequent batch of product, to use this techniques a suitable placebo formulation must first be chosen, solubility of the compounds being studied and accurate simulation of the actual production conditions.

For liquid production either sterile or non-sterile, water is often the best placebo formulation. For sterile liquids WFI is usually selected, where purified water is generally best for non-sterile liquids.

If a single placebo batch can be processed through most or all of the processing steps, it will be exposed sequentially to all possible sources of contamination of the residuals.

If the Placebo method is used to validate the cleaning process it should be used in conjugation with rinse or swab method.  

Along with taking any type of the samples, it is important to use visual inspection as well to ensure the process acceptability

Test the samples Swab Sample, Rinse Sample or Placebo for detection of active or inactive impurity according to relevant testing procedure of the ingredient to be detective and provide quantitative results.

Analytical methods.

Physical Testing 

Along with taking any type of the samples, it is important to use visual inspection as well to ensure the  process acceptability. Visual inspection must be satisfactory before sampling. Visual inspection will be done for visible contamination.

Microbiological Testing

As per Product Testing method, rinse to be checked.

Chemical Testing

The specificity and sensitivity of the analytical methods should be determined. If levels of contamination or residue are not detected, it does not mean that there is no residual contaminant present after cleaning. It only means that the level of contaminant is lower than the sensitivity or detection limit of the analytical method.

Acceptance Criteria

Following Acceptance area will be applied for the cleaning validation.

Change Control

A change control system is to ensure that all changes that might impact the cleaning process are assessed and documented. Significant changes should follow satisfactory review and authorization of the documented change proposal through the change control procedure. Minor changes or changes having no direct impact on final or in-process product quality should be handled through the documentation system. The review should include consideration of re-validation of the cleaning procedure.

Changes which should require evaluation and likely re-validation include but not limited to:

Changes in the cleaning procedure.

Changes in the raw material sources.

Changes in the formulation and/or process of products.

New products.

Changes in the formulation of detergents.

New detergents.

Modifications of equipment 

Cleaning Procedure

Put the distilled water in relevant equipment and keep it on for 15 minutes then remove it.

Put the hot distilled water having temperature at least 80oC and keep it on for 15 minutes.

Wash the equipment and manufacturing area with hot distilled water (80oC) for three times.
