Primary Engineering Controls in Pharmaceutical Compounding, Part 1: Unidirectional-airflow Workstations, Compounding...

Area of Science:

• Pharmaceutical Compounding
• Environmental Control in Healthcare Settings
• Sterile Manufacturing Technologies

Background:

• Maintaining aseptic conditions is critical in pharmaceutical compounding to prevent contamination.
• Primary engineering controls are essential for creating and sustaining contaminant-free environments.
• Airborne particles and microorganisms pose significant risks to compounded sterile preparations.

Purpose of the Study:

• To discuss various types of primary engineering controls used in pharmaceutical compounding.
• To explain the function of laminar airflow within these critical control devices.
• To introduce the scope of the two-part series on compounding environmental controls.

Main Methods:

• Review of primary engineering control devices including unidirectional-airflow workstations, compounding aseptic isolators, and compounding aseptic containment isolators.
• Discussion of laminar airflow principles as applied to these controls.
• Examination of ancillary equipment such as casters and hydraulic lifts in relation to these controls.

Main Results:

• Several types of primary engineering controls are available to achieve contaminant-free compounding environments.
• Understanding laminar airflow is key to the effective operation of these controls.
• Ancillary equipment plays a role in the practical application and mobility of these critical devices.

Conclusions:

• Primary engineering controls are fundamental to ensuring the safety and efficacy of compounded pharmaceuticals.
• The selection and proper use of these controls, including their associated airflow dynamics, are paramount.
• This article serves as an introduction to essential environmental controls in compounding, with biosafety cabinets to be discussed in part two.
