Aseptic filling room

Aseptic Filling Rooms and Aseptic Processing Area... 

The loading of lyophilizers is accomplished under ISO 5 environmental conditions within the aseptic processing area. Several possible locations are possible within the aseptic fill room itself, in a separate room adjacent to the fill room, or in a separate room remote from the fill room. There are pros and cons with each of these selections which should be carefully considered in the facility design. There is a... 

Double-Ended Autoclaves In many industrial applications autoclaves will be bridges between areas with different cleanliness classifications. The two main scenarios are that of an autoclave being loaded in a nonsterile preparation area for its sterilized contents to be unloaded in an aseptic filling room, and of an autoclave being loaded in a clean filling room for its sterilized contents to he unloaded into an uncontrolled packing area. In either example the risk is com-... 

For sterile Filtration of ophthalmics and small-volume parenteral products it is not unusual to Find several Filters mounted in series. For instance a compounded bulk product may be Filtered through the wall from a dean area into an aseptic filling room. In these cases there are usually two filters mounted in... 

Terminal HEPAs should be located in the air supply ducts as close as possible to their point-of-use exit grilles. For aseptic filling rooms they should be specified at 99.997% efficiency. They may be set in one of two types of housing, front-withdrawal or back-withdrawal, depending on the mechanism for removal and replacement. Back-withdrawal HEPAs can be removed from outside the protected environment front-withdrawal types have to be removed via the protected environment itself. Neither type is suited to removal and replacement with the area remaining sufAciently protected for operation, but front-withdrawal is preferable because it leaves the duct work intact and not subject to contaminaAon from unprotected service voids during removal. 

Vacuum cleaners, however, are only suited to areas outside aseptic filling rooms because of their relative inefficiency of collection of smaller particles 11], leaving wet wiping with disinfectants as the standard method used for cleaning filling rooms. 

Services should be provided from outside aseptic filling rooms, either by routing within the fabric of the surrounding walls, floors, or ceilings, or from... 

Liquid formulations should be prepared in an area that Is as clean as possible. Water for parenteral products should be of pharmacopoeial Water for Injection quality. Mixing vessels and other equipment should be cleaned and disinfected. It is normal for these areas to be provided with filtered air from HEPA fllteis of somewhat lower efficiencies than those providing protection to aseptic filling rooms. Sterilization of liquid products should be by filtration through... 

Filtered sterile dosage forms may be collected in sealed vessels in the aseptic filling room for subsequent connection to the filling machine, or the filler outlet may be connected directly to the filling machine. 

Any storage of sterile dosage forms or sterilized components in aseptic filling rooms should be in sealed containers, and these should be afforded additional localized filtered air or laminar flow protection to prevent their contents becoming contaminated when they are opened. 

Individuals with medical conditions that may lead to abnormally high shedding or dissemination of microorganisms should not be chosen to work in aseptic filling rooms. Conditions include excema, psoriasis, styes and boils, coughs, colds, and hay fever. 

Access of personnel to aseptic filling rooms should be via a defined route, through a series of at least two changing rooms progressively meeting higher standards of cleanliness, and against a pressure differential. 

The principal method of protecting aseptic filling rooms from contamination by personnel is through the provision of effective containment of their... 

Last but not least, best practice is for aseptic changing rooms to be equipped with horizontal laminar flow protection, providing a gradient of air cleanliness from the filter bank situated at the cleanest end (access to the aseptic filling room) of the room to exit registers at the entrance. 

In Fig. 10, two solid dosage form aseptic filling rooms share common gray areas. Once again the flow of vials from empty to full follows a U-shaped track, and again there are two major gray areas. Within each gray area the same personnel can service both lines with vials or closures. 

In 1981 Whyte [13] proposed a model to describe the potential probability of microbiological contamination of the contents of containers originating from the air in the environment of aseptic filling rooms. The model incorporated three additive effects ... 

The microbial and particulate quality of aseptic filling rooms is maintained by dilution as well as filtration. The rate of exchange of room air is important to the contribution made by dilution. Room air should be changed ai least 20 limes per hour. Around 90% of the air should be recycled through the filters. There should also be a satisfactory pressure differential (minimum 0.05 inches WG or 15 pa.scals) between clean rooms and adjacent less protected areas.
