Hello good people of the world! Today’s post is high-level regarding serialization. Serialization is a process mandated by the world’s regulatory agencies to reduce counterfeit drug products in the market. Besides being costly to drug companies, counterfeit drug products are often less efficacious and less safe than the real drug they are purporting to be. Additionally, counterfeit drug products can be contaminated with other APIs and/or toxic excipients.

Hello good people of the world! Today’s post is about Corrective Action / Preventive Action, typically referred to as CAPA. CAPA is an integral part of any Quality System, and certainly one of the first things an agency will look at in any audit.
There is a ton of good information out there already on CAPA, including FDA’s own guidance from 2014.
The key points of the CAPA program are:
- Issue identification, i.e. ensuring the issue is truly understood and well documented
- Root cause analysis, i.e. identifying the root cause of the issue
- effectiveness check, i.e. verifying actions have actually resolved the issue
What tips have you learned from your CAPA program? Comment below.
Hello good people of the world! As you probably know, one of the first things an agency is likely to ask for in an audit is your company’s organization chart. They want to know how the organization is structured, and particularly where the quality unit fits in.
If you have a SharePoint tenant, I have an offer for you. For a limited time, MWV, in conjunction with dikuw.com, is offering a free SharePoint Add-in for generating organization charts. This add-in integrates with your existing SharePoint On-Premise or Online service, and gives a secure, centralized location for your org chart. The custom interface makes it easy to navigate and update the chart in real-time.
Get all the details and download the add-in here: http://www.dikuw.com/OrgChart.html

Hello good people of the world! Today’s post is an overview of environmental control and monitoring for aseptic processing.
Applicable references for the US are:
- FDA Guideline for “Sterile Drug Products Produced by Aseptic Processing” September, 2004
- FDA Guideline for the submission of “Documentation for Sterilization Process Validation in Applications for Human and Veterinary Drug Products”
- 21 CFR Part 211 — Current Good Manufacturing Practices for Finished Pharmaceuticals
Environmental control is designed to prevent microbiological contamination of sterile products.
Environmental monitoring is designed to detect microbiological contamination in aseptic processing areas.
Scope: Environmental control and monitoring is a required part of aseptic processing, i.e. where “terminal” sterilization is not possible. Terminal sterilization means the finished drug product is sterilized at the last step of the process via heat, radiation or other. Many pharmaceuticals and most biologics do not tolerate terminal sterilization, thus the importance of aseptic processing.
- Air particle count: maintaining air particle counts is critical to aseptic processing, because particles themselves can be harmful, and likely carry microorganisms.
- Cleanroom design: for the aseptic core (where critical aseptic process steps occur, e.g. where product is open to the environment) the FDA recommends class 100. The core should surrounded by class 1,000 or class 10,000 areas.
- Air pressure differentials: the FDA recommends a 10-15 Pascal pressure differential between rooms of differing classification, with the higher pressure in higher-class rooms, so that air naturally flows outward to the lower class rooms.
- HEPA filtration: High Efficiency Particulate Air (HEPA) filters should be used in class 100 rooms to aid in particle removal
- Equipment: should be cleanable and non-shedding. Stainless steel is the preferred material of construction for equipment surfaces.
- Process design: processes should be designed with minimizing contaminate risks in mind (e.g. don’t force operators to reach over open product)
- Process Validation: media runs should be performed to demonstrate the process can run aseptically
- Air quality measurements should look at viable and nonviable particulate levels
- Particle counting: ongoing monitoring should look at particle counts in critical areas
- Active sampling: devices such as impaction and membrane samplers should be used to evaluate aseptic processing areas
- Passive sampling: settling plates should be used to collect microbial information
- WFI and other excipients: should be routinely tested for microbial/particulate load
- Personnel: the greatest single contributor of particulates and microbes in a cleanroom. Steps (training, gowning, testing) must be taken to minimize risk
