Manufacturing area with new equipment having high capacity compared to previous one (Production Line) i.e. FBD, RMG, Co Mill and Container Mixer. Manufacturing of Metformin ER 500mg tablets is planned to do in new area with new equipment. As the size and capacity of the equipments are bigger than previous equipments, batch size of Metformin ER tablets is increasing from 0.4 mio to 0.6 mio. As the production in new area and new equipment, qualification of area, equipment, water and air was carried out as per qualification protocol. Now, further the process of optimization was performed for Metformin ER tablets by identifying the critical Process parameters i.e. standardization batch (BATCH I). Before going to start process validation, one standardization batch was taken, where the process optimization of critical parameter like mixing speed, mixing time, lubrication time was carried out; fast, 15 min, 15 min respectively the results for that. Three process validation batches (PV-1,... Это и многое другое вы найдете в книге Process Validation, Area and Equipment Qualification (Mitesh Patel,Kanu Patel and Mukesh Patel)
