What is the Origin of Pharmaceutical Quality Systems?

The concept of formalized quality systems in pharmaceuticals arose from the need to standardize manufacturing processes and prevent catastrophic product failures that could endanger public health. The modern PQS framework was developed and continually refined by international regulatory bodies, emphasizing a proactive, science-based approach to quality assurance. Its origin is fundamentally rooted in public health protection and regulatory compliance.

What is the Mechanism of Pharmaceutical Quality Systems?

The PQS mechanism operates through a continuous cycle of planning, execution, monitoring, and improvement, often referred to as the "Plan-Do-Check-Act" model. It requires rigorous control over all critical aspects of production, including raw material testing, personnel training, equipment calibration, and deviation management. This systematic control ensures that every batch of a hormonal preparation or drug substance consistently meets its predetermined quality attributes and regulatory specifications.

Pharmaceutical Quality Systems

Meaning

Pharmaceutical Quality Systems (PQS) represent the comprehensive, structured framework outlining the organizational structure, procedures, processes, and resources necessary to ensure that pharmaceutical products meet the required standards for quality, safety, and efficacy. This system integrates the principles of Good Manufacturing Practice (GMP) and Quality Risk Management throughout the entire product lifecycle, from development to distribution. A robust PQS is a mandatory regulatory requirement designed to minimize risks and ensure consistent product quality for the patient.
