Following are the critical stages or steps as a part of the Change Management process are: Raise a Change Request Cross Functional ... Read More
A Brief Overview of the 505 Regulatory Pathways
The FDA recognizes three primary pathways for the approval of new drugs and abbreviated new drug applications (ANDA): the 505(b)(1) NDA, 505(j) ANDA, and 505(b)(2) NDA. Each pathway serves a distinct purpose in the drug approval process. 505(b)(1) NDAThe 505(b)(1) NDA is a comprehensive application that relies entirely on original ... Read More
505(b)(2) Submission Process
The 505(b)(2) submission journey involves four crucial steps: candidate identification, candidate assessment, product planning, and the pre-IND meeting. Candidate IdentificationThe first step involves selecting drug products compatible with the 505(b)(2) pathway, a crucial action that mitigates the risk of failure. It typically involves a few nonclinical studies. During Phase 1, ... Read More
Difference Between C8 and C18 Columns
C8 and C18 are both types of reverse-phase chromatography columns, but they differ in their: Carbon chain length: Hydrophobicity: Retention characteristics: Separation range: Column selectivity: In summary, C8 columns are used for smaller, more polar molecules, while C18 columns are used for larger, more non-polar molecules. The choice between C8 ... Read More

TIP Speed Calculation for RMG Process Scale-Up
Scaling up in pharmaceutical manufacturing, especially with Rapid Mixer Granulators (RMG), requires careful attention to “Motion similarity between lab RMG and production Large RMG “, particularly in maintaining consistent “tip speed”. Here’s why this is crucial:Tip speed—the speed at the edge of the rotating impeller directly affects mixing efficiency and ... Read More
Deviation Management and Root Cause Analysis
In the life sciences industry, maintaining the highest quality standards is non-negotiable. Deviations, or departures from established procedures, are inevitable, but how we manage them makes all the difference. Here’s why Deviation Management and Root Cause Analysis (RCA) are pivotal: Ensuring Compliance and Safety: Systematic Investigation: Preventative Measures: Continuous Improvement: ... Read More
Surfactants in Dissolution
We have many factors to consider when making a dissolution method. What apparatus, speed, filter choice, etc. Of these factors, the one I get the most questions about is media selection – especially surfactants in media selection. So, what is a surfactant and why do we use them? What do ... Read More
How Do Regulated Companies Balance Quality and Compliance
First of all quality and compliance are related but distinct concepts. Quality refers to the degree to which a product or service meets or exceeds customer expectations. It’s about delivering value and ensuring satisfaction. Compliance, on the other hand, involves adhering to laws, regulations, standards, and guidelines set by external ... Read More

Verification of OOS Results | EDQM Guidelines
VERIFICATION OF INITIAL OUT-OF-SPECIFICATION RESULTS SCOPE The objective of this Annex is to describe the steps to follow for the management of out-of-specification (OOS) testing results. The failure investigation may also be triggered if validation criteria defined by the method or laboratory are not met, including out-of-trend (OOT) results. To ... Read More
