Pharmaceutical requirements Sterility
During manufacture
Use of special aseptic technique during manufacture that minimizes
the possibility of contamination from human or extraneous material:
• Manufacturing area is maintained bacteria-free by:
➢ Use of ultraviolet lights and a HEPA (high efficiency particulate
air) filtered air supply
➢ The disinfectant solutions are filter sterilized because they may,
themselves, be a source of contamination with resistant organisms.
