Root Cause Analysis (RCA) is essential for identifying and addressing the underlying causes of problems to prevent recurrence. Below are 7 powerful tools that every quality professional should master: ❶ Ishikawa Fishbone Diagram: Organize potential causes into categories for better visualization. ❷ Pareto Chart: Prioritize causes by focusing on the vital few rather than the…
Autoclave Validation Risk: Uneven temperature distribution could lead to incomplete sterilization. QRM Application: Conduct risk assessments for load configurations and identify critical spots for temperature sensors to ensure uniform heat distribution. Cold Chain Validation Risk: Temperature excursions during storage or transport might compromise product quality. QRM Application: Use risk-based mapping to monitor high-risk areas (e.g.,…

Is there a requirement to run a leak test of lyophilizer after every cycle in GMP pharmaceutical production? GMP regulations do not mandate leak testing after every lyophilization cycle, but periodic testing is required to ensure equipment integrity and product quality. The frequency is determined by risk assessment, internal procedures, and process criticality. 1.1 European…

To make the effervescent reaction happening a carbonate component and an acid are required. In the presence of water, carbon dioxide is formed, and the tablet disintegrates. This leads to the typical bubbling. Effervescent tablets have a separate monograph in the pharmacopoeia which e.g., limits the disintegration time. Typical Excipients Disadvantages of Effervescent Tablets Effervescent…
Wetting agents are surface-active substances which reduce the surface tension of water. By improving the wettability of hydrophobic substances, they increase the dissolution rate of APIs. Liquid and Paste-Like Wetting Agents in Wet GranulationA lot of these standard surface-active substances are liquid or have a paste-like consistency and can therefore only be processed during wet…
