最近看了网上流传的诺华的清洁验证SOP,里面关于中间体换批清洁规定的目检,但是也有许多其它的要求,可以参考一下
Intermediate to Intermediate - Same API
The following criteria applies for carry-over of intermediate residues processed in
multipurpose equipment in an Intermediate to Intermediate sequence of the same API:
The contamination by an intermediate in th e following intermediate of the same API
must be no more than the carry over by the process itself. The equipment must be
visually clean.
Microbiological and endotoxin (as applicable) contamination of the API by the
equipment must be prevented. Also, the time between cleaning and equipment re-use
must be considered in the cleaning validation procedure. The limits for the
microbiological and endotoxin contamination of equipment surfaces in contact with
APIs must be in accordance with the existing module “Cleanliness Zoning in the
Manufacture of APIs” (Non-sterile/sterile).
Where open handling of product occurs, the surrounding areas (floors and walls) must
be "visibly clean" of the API /intermediate and detergent / disinfectant. It may be
necessary to do an initial evaluation of the floors and walls to show that they are in
fact clean following the cleaning procedure.
