What is it about?
This article presents a statistical analysis of the critical quality attributes of 1,2-dihydroxypropane (also known as propylene glycol or methyl ethyl glycol) as a pharmaceutical excipient. The study focused on the assay and water content tests of 34 batches of the manufactured excipient using a standard analysis method according to the British Pharmacopoeia (BP). Exploratory Shewhart charts, a statistical process control (SPC) tool, were used to visualize and analyze the data. The results showed that the data for both assay and water content did not follow a normal distribution. Additionally, several out-of-control signals were observed on the Shewhart charts for both quality aspects, indicating that the process was unstable and unpredictable. Although no results exceeded the specification limits, the presence of out-of-control signals suggests a need for improvement in process control to ensure consistent quality of the excipient. The study recommends that the supplier implement measures to improve process control and reduce variability in the critical quality attributes of 1,2-dihydroxypropane. This could involve investigating the root causes of the out-of-control signals and taking corrective actions to address them. Additionally, the supplier may need to review the quality limits for the excipient to ensure they are appropriate and reflect the actual variability in the manufacturing process. Overall, this study highlights the importance of statistical analysis in monitoring and improving the quality of chemically manufactured compounds. By identifying and addressing process instabilities, suppliers can ensure a consistent and reliable supply of excipients, which is essential for the safety and efficacy of pharmaceutical products.
