Quality Assurance and Quality Control in Pharmaceutical Field: A Systematic Review

For many years, the pharmaceutical industry has faced ongoing challenges related to product quality, compliance, and process consistency. These quality failures often result in significant economic losses, product recalls, regulatory sanctions, and potential risks to patient safety. However, these issues can be greatly minimized if the sector fully adopts a comprehensive Quality Assurance (QA) approach, similar to the systems that have proven highly effective in other regulated industries such as food manufacturing and bio technology .To support this shift, pharmaceutical manufacturers, regulatory authorities, and product stakeholders must understand the importance of quality assurance and consistently apply it throughout the drug development and production lifecycle. When integrated effectively, QA and Quality Control (QC) systems strengthen internal oversight, reduce defects, enhance regulatory compliance, and ensure that medicines delivered to patients meet the highest safety and efficacy standards.Internal Quality Control (QC) and Quality Assurance (QA) are increasingly critical components for pharmaceutical project managers and production teams. Failures in drug formulation, packaging, stability, or manufacturing processes can lead to product recalls and interruptions in supply chains, in addition to compromising patient well-being. Therefore, QA and QC represent essential frameworks for improving reliability, uniformity, and the overall quality of pharmaceutical products.
