Oral Solid Dose – Architectural Considerations

Hello good people of the world! Today we’re talking about architectural considerations in the design of oral solid dose (OSD) manufacturing facilities.

In addition to normal architectural standards, the following must be considered for OSD manufacturing facilities:

• Manufacturing process flow
• Personnel flow
• Equipment flow (clean and dirty)
• Waste flow

Risks to consider when mapping flows include:

• Risk of contamination from outside contaminates
• Risk of cross-contamination
• Risk of mix-up

Risk mitigations should consider:

• Process containment
• Isolators
• Environmental controls
• Room size
• Transition spaces and airlocks
• Personnel controls such as gowning
• Administrative controls such as frequency of operation

Oral Solid Dose – Isolation and Containment

Hello good people of the world! Today we’re going to talk about isolation and containment considerations in oral solid dose manufacturing. The purpose of isolation and containment is to control the level of pharmaceutical ingredient exposure to personnel and the environment. It is typically not possible to eliminate all exposures, so we try to reduce it to a tolerable level, which must be defined.

The CFRs and other regulations require manufacturers to limit exposure to customers of any undesirable substance. Limits have been established by industry group and regulatory bodies, and quantify things such as Allowable Daily Exposure (ADE).

Things to look at when considering isolation and containment include:

• Material flow
• Personnel flow
• Operator interventions
• Sampling
• Waste flow
• Maintenance procedures
• Utility interactions

Isolation and containment risks must be evaluated and mitigated to get a solid handle on the implications. A multi-disciplinary approach must be used. Migations may include:

• Physical barriers
• Air control
• Cleaning procedures
• Disposables
• Training

What considerations come in to play in your isolation/containment strageties? Comment below!
