QUALITY by DESIGN (QbD)

WHAT IS QUALITY BY DESIGN? “You can’t test quality into drug products” has been heard for decades – so what’s new? ICH Q8 Pharmaceutical Development focuses on the content of the Module 3.2.P.2 of the Common Technical Document (CTD) and promotes the concept of QbD. It supports knowledge gained through the lifecycle of a product … Read more

EQUIVALENCY BETWEEN EQUIPMENTS:

Pharmaceutical manufacturers have an obligation to ensure that their manufacturing equipment is properly designed, installed, tested, operated, and maintained throughout their service lifetimes. During these service lifetimes manufacturing equipment will likely require both preventive and corrective maintenance activities that may involve the replacement of parts within the systems. Parts replacements must be performed under the … Read more

UNDERSTANDING PRE-REQUISITES FOR TECHNOLOGY TRANSFER

Technology transfer is both integral and critical to drug discovery and development process for new medicinal drug products. A major decision focuses on that point where the idea or process is advanced from a research-oriented program to targeted toward commercialization. Generally, the cost of product development rises dramatically during the pilot scale-up and initial production … Read more

UNDERSTANDING ON WORKING PRINCIPLE OF BLENDER

Blending in its simplest form is the combining of two or more materials to produce a homogeneous mixture. These materials may be any combination of particulate (solids blending) or particulate and liquid (liquid-solid blending). Normal tumble blending of free-flowing materials provides a gentle mixing action. For materials that tend to lump or for high intensity … Read more

UNDERSTANDING ON WORKING PRINCIPLE OF RAPID MIXER GRANULATOR (RMG):

Homogenous mixing of dry & wet powders, de-agglomeration / de-lumping of wet mass and fast dispersion of binding agent. Dust free, high free flowing dosing particles, high uniformity of granule size. AC frequency control for bottom driven Impeller Mixer with 3 or 4 blades with exclusive scrape side design and Chopper positioned to make granules. … Read more

UNDERSTANDING ON WORKING PRINCIPLE OF FLUID BED DRYER (FBD):

Fluid Bed Dryers (FBD) are primarily used in almost all chemical, pharmaceutical, food, dyestuff and other process industries to dry materials by fluidization with hot and / or dehumidified air, which creates a turbulence in the wet product (not totally liquid) while flowing through it. WORKING PRINCIPLE: The atmospheric air is sucked in the dryer … Read more

UNDERSTANDING ON WORKING PRINCIPLES OF SIFTER (VIBRATORY SIFTER):

VIBRO SIFTER, VIBRO SCREEN: Vibro separators are circular gyratory screens used to separate solids from solids and liquid from solid. Vibro Sifter consists of Specially Designed Motor mounted vertically at the center of the base plate of the Screen. The Screen is in between feeding hopper and bowl. The material is fed on to the … Read more

UNDERSTANDING OF SUPAC GUIDELINES (SCALE UP AND POST APPROVAL CHANGES):

This guidance provides recommendations to sponsors of new drug applications (NDA’s), abbreviated new drug applications (ANDA’s), and abbreviated antibiotic applications (AADA’s) who intend, during the post approval period, to change: SU: Scale-up during original dossier assessment. Note that this is not SU during development. Consider changes made after the Biobatch   PAC: Post-PQ/post-approval, i.e. Variations. … Read more

BASIC UNDERSTANDING OF DIFFERENT EQUIPMENT AND CRTICAL OPERATING PARAMETRS:

Equipment must be located, designed, constructed, adapted, and maintained to suit the operations to be carried out. The layout and design of equipment must aim to minimize the risk of errors and permit effective cleaning and maintenance in order to avoid cross-contamination, build-up of dust or dirt, and, in general, any adverse effect on the … Read more
