Analytical Method Validation | Avoiding Common Pitfalls in CTD Submissions

Analytical Method Validation | Avoiding Common Pitfalls in CTD Submissions

As a Stability Assessor at the Egyptian Drug Authority, I frequently review CTD files, and I’ve noticed recurring mistakes in the Analytical Method Validation section. These oversights not only delay regulatory approvals but also question the reliability of the data presented. Here are some common pitfalls to avoid: 1. Incomplete Validation Reports: Failing to address…

Key Elements of an Analytical Worksheet

Key Elements of an Analytical Worksheet

Title and Identification:Including the type of test being performed, batch number, sample ID and date of analysis. Procedure Steps:Clearly outlining each step of the test method and procedures along with the references. Raw Data Entry:Areas to record experimental observations, instrument readings and raw data. Additional data prints like spectra should be attached. Calculations:Sections to perform…

Identification Tests in Pharmaceutical Analysis

Identification Tests in Pharmaceutical Analysis

These tests are designed to confirm the identity of the active pharmaceutical ingredient (API) and other components in a drug formulation. The identification of pharmaceuticals is a fundamental step in quality control, as it helps prevent errors in manufacturing and ensures that the final product meets the required specifications. Here are some common identification tests…

Why Do We Do pH in the Pharmaceutical Industry?

Why Do We Do pH in the Pharmaceutical Industry?

pH is a measure of a solution’s acidity or alkalinity. In the pharmaceutical industry, pH is important because it can affect the stability, efficacy, solubility, and bioavailability of drugs:   pH is mesured in the pharmaceutical industry to check/ensure: 1. Drug stability The stability of many drugs is affected by pH.  For example, some drugs…

Pre-Requisites for Analytical Method Validation

Pre-Requisites for Analytical Method Validation

Prerequisites is usually a checklist which is sent to the Receiving Laboratory which in most of the cases is the Quality control laboratory of the manufacturing.   This checklist is prepared by the Department or the team which is involved in the method validation/verification/transfer activity and contains all the things which are required and needed…

Analytical Procedure Development

Analytical Procedure Development

Since there is no ICH guideline on Analytical Procedure Development, applicants often report analytical validation results alone and rarely present performance evaluation with analytical development outcomes.   This makes regulatory communication ineffective especially when non-conventional (for example, real time release testing) analytical procedures are employed.   Additionally, the lack of guidelines precludes the applicant from…
