Aligning Equipment Deviations with Change Control and Stability Impact

In pharmaceutical manufacturing and stability programs, equipment deviations are inevitable. Whether due to calibration drift, equipment malfunction, or environmental excursions, such deviations can threaten the reliability of stability data. When not addressed promptly and systematically, they may lead to batch rejections, data invalidation, or even regulatory observations. Therefore, aligning deviation tracking with change control procedures…

Regulatory Deficiency Letters Related to Outsourced Stability Testing

Pharmaceutical companies often rely on Contract Research Organizations (CROs) or third-party labs to conduct stability studies. However, this outsourcing model carries significant regulatory risk. Many regulatory deficiency letters from authorities like the USFDA or EMA cite critical issues with outsourced stability testing. This article explores the recurring failures, examples from real letters, and how to…
