European Warning Letters? Is there such a thing? Basically, no. Warning Letters are issued by the US-American FDA. However, there is something "comparable" namely the "Non-Compliance Reports" published in the Eudra GMDP database. Now, one may question what the authorites has complained about in the last 3 months.
Water systems are one of the most important systems in the pharmaceutical industry. What are the GMP requirements for the qualification and running of these systems? The US GMP regulations (21 Code of Federal Regulation (CFR) 210/211) do not provide much concrete information on this. There is still a Guide to Inspection for FDA inspectors from the early 90s. So, what does the FDA expect today? A current Warning Letter provides a few answers.
The new ICH Q12 Guideline for Post-Appproval Changes has been adopted in Singapore in November 2019. The document provides guidance on a framework to facilitate the management of post-approval CMC changes.
When it comes to process validation, FDA's Process Validation Guidance from 2011 is state-of-the-art. It is interesting to see how the FDA would like to see the guidance implemented. Here, the findings described in Warning Letters issued after FDA inspections can help. A recent Warning Letter regarding deficiencies to 21 CFR 211.100 from October 2019 mentions the following.
An USP Stimuli article on Elastomeric Components for Inhalation Packaging / Delivery Systems has been published in Pharmacopeial Forum, proposing to test for nitrosamines in elastomeric components used for inhalation products.
FDA's Warning Letters provide a valuable source of detailed information and can be helpful in preparing for an inspection, making a more detailed analysis worthwhile. Read more here about what FDA inspectors have discovered in recent months regarding frequent weaknesses at GMP-liable pharmaceutical manufacturers.
The data integrity topic raises a number of questions. Current questions are addressed in a loose sequence of News. Question 6: How can I handle analysis devices that are connected to a LIMS via a middleware? The manufacturer does not allow access to the original data in the automated analyser though.
Cannabidiol (CBD) is currently marketed in a variety of product types, such as oil drops, infused pouches, capsules, syrups, teas and topical lotions and creams. Therefore, the FDA is working on the evaluation of regulatory policies related to cannabis and cannabis-derived ingredients.
The main material used in plant engineering is stainless steel. The variant 316L is regarded as standard; material incompatibilities of steel with the product play almost no role. This is different for plastics. Beside the leach-out, ageing and surface finishing, other quality features are often specified. Now, what are the general requirements for plastics in pharmaceutical plant engineering?
Nitrosamines have already been detected in a large number of medicinal products. Where do they come from and how are they transferred to the final product? Read more here about the causes for nitrosamine impurities that have already been identified and what should absolutely be taken into account in the risk assessment of medicinal products.
