FDA Warning Letters for International APIs in 2011

API Warning Letters to International Manufacturers

FDA issued at least ten Warning Letters to international manufacturers of active pharmaceutical ingredients in FY-2011. Manufacturers in both China and India, the world’s largest exporters of APIs, received three Warning Letters each from FDA. Manufacturers in Spain, the UK, Canada, and Japan each received one Warning Letter from FDA. These metrics show both the domination of China and India in the API market as well as the continued dependence on international manufacturers for APIs destined for the U.S. market.

Deficiency Categories:

The violation that dominated the charges cited by FDA in FY-2011 related to quality control, cited in four Warning Letters, two to China and one each to Canada and Japan.

Failure to Have Procedures for Cross Contamination

Another violation that is sure to cause concern with FDA is the failure to prevent cross-contamination. When I attended FDA API inspection training in 2000 cross-contamination, particularly with anti-biotics, was a major concern. It continues to be with API manufacturers in both India and China being cited for the “Failure to have appropriate procedures in place to prevent cross-contamination.”

Out of specification (OOS) laboratory results are always a concern of FDA and landed on Warning Letters to manufacturers in India and Spain. Other citations include:

= Water purification for APIs used in parenterals

= Failure to establish a stability program to monitor APIs

= Failure to perform at least one identity test of each batch of incoming material

= Validation of analytical methods used to test APIs

There are no big surprises here but it shows that regular surveillance of API vendors is an absolute necessity for the manufacture of quality drug products. What is of interest is that GxP Perspectives couldn’t find any domestic Warning Letters for APIs. That doesn’t mean they don’t exist, only that they couldn’t be easily located. Unfortunately, FDA lists API Warning Letters in any number of classifications for GMPs for finished pharmaceuticals. However, they don’t seem to list them for APIs. With all the razzle-dazzle taking place on FDA’s website, you would think they could come up with a consistent way to list API Warning Letters. Who knows, maybe next year.

FDA Issues 5 New International Warning Letters

FDA international warning letters

FDA's Increased International Presence

The “Most Recent Warning Letters” section of the FDA website lists five Warning Letters to international firms. The Warning Letters were posted on May 10 and will disappear into the Warning Letter labyrinth on the website in a few days (see previous post). They are to firms in both Europe and Asia and come from four different centers: the Center for Devices and Radiological Health; the Center for Drug Evaluation and Research (Active Pharmaceutical Ingredient (API); the Center for Biologics Evaluation and Research; and the Center for Food Safety and Applied Nutrition (two Warning Letters for Seafood HACCP).

The Warning Letters do not state if the inspections were conducted by one of the FDA’s new International Resident Posts- but it is likely that the FDA’s increased global presence contributed to the enforcement actions. FDA now has offices in China, India, Belgium, and Costa Rica. This is addition to FDA’s International Inspection Cadre which is primarily drawn from FDA Field Investigators (Consumer Safety Officers) working for the 20 FDA District Offices across the country. The fact that different offices are issuing Warning Letters around the world at the same time gives a clear indication of FDA’s increased international enforcement efforts.

Read the Warning Letters:

Hong Kong – Medical Devices

Spain – Active Pharmaceutical Ingredients

Sweden – Biologics cGMP

Korea – Seafood HACCP

On the Blogroll: Last week we had the FDA Lawyer’s Blog. This week I want to highlight a recent article on the FDA Law Blog on “FDA Warning Letter ‘Close Out’ Process Not Working.”
