I have to validate the cleaning process of an equipment train that is used to manufacture the same product (same API), same excipients but different lot sizes/ API amount per product presentation. That is Product A strenght 5mg and Product B strenght is 250mg and they are NOT manufactured using a common blend.
The validation requirements according to the site procedures is visual inspection, micro testing and chemical residues (for non dedicated equipment only).
Should I consider these as two different products and validate the cleaning process using the Product B (visual, micro and chemical) or consider Product A and Product B as the same product and validate the cleaning process with visual and micro only?
Thanks in advance for your help
