The Validation Department – a Producer of Data

Data Production

Hello, good people of the world! So you’re in Validation. Or any part of the Quality department. You don’t manufacture anything, you don’t sell anything – what is your role?

You are in the business of information, and you have many customers. Your first and most important customer may be the regulatory agencies your product(s) are subject to, but you’re also serving Manufacturing, Engineering, and the company owners and shareholders. That means you better be good at handling information. Continue reading The Validation Department – a Producer of Data

Recovery Studies – What the Heck?!

Recovery

Hello, good people of the world! Recovery studies are studies to support surface swab processes. They typically involve “spiking” a “coupon” made from a particular material with a known amount of the contaminate you’re interested in, and then systematically quantifying the amount recovered via the swab process.

You’ll need to perform recovery studies for all product-contact materials you have in your manufacturing process. These typically include 316L stainless steel, PTFE, glass, etc.

Metrics

Hello, good people of the world! If you know me, then you know I’m into “metrics” – ways to evaluate the health of a system or process quantitatively. We know finding and correctly interpreting the “right” metrics is not trivial, and looking at the “wrong” metrics can do more harm then good.

ISPE has recently released a whitepaper suggesting quality metrics for the FDA to use in their inspection process. I’ve uploaded a copy Continue reading Quality Metrics

Stability – What is it and Why is it Important

Stabliity

Hello, good people of the world! Stability is the characteristic of your drug product to withstand degradation or changes due to environment factors, typically temperature, humidity, and light.

World Health Organisation (WHO) has published guidelines addressing drug stability since 1996. WHO introduced the concept of 4 climatic zones, derived from a scientific paper published in 1993: Grimm, W., Drug Development and Industrial Pharmacy (1993) 19:2795-2830.

Parts Washer Qualification – PQ

Parts Washer

This post is about Parts Washer qualification. This covers any manner of automated system that cleans parts out-of-place (Clean-out-of-place = COP). This includes process parts washers, glassware  washers, laboratory parts washers, etc. all of which may be termed COP washers.

The scope of a performance qualification of a washer is the performance of the equipment with defined recipe(s) and load(s). Be sure to capture the recipe and load configuration in the protocol prior to execution or as part of the execution itself. This is how the recipe and load configuration become “validated.” The recipe includes all steps and parameter values, and the load includes what parts or components will be washed and how they will be arranged. You’ll need to include a picture or diagram. Continue reading Parts Washer Qualification – PQ
