QUOTATION REQUIREMENTS
To assist ALS Pharmaceutical in providing an accurate quotation can you please provide the following information for your stability study by completing Table 1 on the following page:
1. Temperature & Humidity conditions the samples will be held under, i.e. 2-8°C, 25°C/60%RH, 30°C/65%RH, 40°C/75%RH (RH = Relative Humidity)
2. The time points when the samples are to be tested
3. Tests required including the specifications. These are generally provided by the client from the product’s specification
Is any method validation required? If so then please also complete table 2 on page 3.
As a guide and to assist with the stability and method validation requirements, please see the information provided here.STABILITY:
If the product specifications are not finalised or available then the following tests can be considered:
1. Appearance: This description should be based on the Specification sheet for the product.
a. Creams & Liquids (e.g. Dark blue non viscous liquid with a eucalyptus odour)
b. Tablets (e.g. Round white biconvex tablet with a logo & breaker bar)
c. Capsules (e.g. Soft Gel capsule with a clear fill content)
2. Physical Testing
a. Creams & Liquids (e.g. pH, Specific Gravity, Viscosity)
b. Tablets (e.g. Diameter, Thickness, Hardness, Friability, Disintegration, Uniformity of Weight)
c. Capsules (e.g. Disintegration, Uniformity of Weight or Fill Weight)
d. Weight Loss / Gain
3. Actives – method validation recommended
4. Preservatives – method validation recommended
5. Related Substances – method validation recommended
6. Microbiological Tests (e.g. TGO77), Preservative Efficacy
METHOD VALIDATION:
1. Where relevant it is a mandatory requirement that a method is validated when quantification of content is performed.
2. When a validated customer method is supplied, Method Transfer Validation should be performed. Where Pharmacopeia methods are employed for assay, Method Verification should be performed.
3. Where the client stipulates that validation is not required or when the method does not warrant validation, for example, in the testing of trial or R&D batches, the statement ‘The method/s have not been validated for this product’ will appear on the report.

* These ‘Full’ validation parameters are recommended to comply with ICH guideline Q2 (Validation of Analytical Procedures: Text and Methodology). However if there are valid reasons for reducing the parameters assessed then the ‘mandatory’ parameters are acceptable. Examples being complementary medicines, preservatives, sunscreen actives, Elemental method validation via ICP-OES/MS.
Other Method Validation Related Activities – For example:
· Method Transfer – The requirements for method transfer are generally client dependent and ideally should include a comparison of results between the transferring and receiving laboratory, e.g. Repeatability testing at both sites on three batches.
· Method Verification – Generally employed for standard methods (e.g. Pharmacopoeial), including Linearity/Range, Repeatability and System Suitability.
· Dissolution method validation – Generally only limited method validation is required, e.g. Linearity/Range, System Suitability and accuracy (Vessel spiking). This is however based on the fact that the analytical analysis method has previously been validated.
