My question is concerning residual analyses performed on products containing multi APIs during cleaning validation.
I know that, according to the FDA regulations, we must perform a residual analysis for the API within a product during cleaning validation. If the product contains more than one API, are we supposed to perform individual analyses for each of the API within the product or can we choose a particular API, which has the lowest dissolution rate, and omit the rest of the analyses? I hope my question is clear enough.
Thanks for your concern, in advance.
