What gave you the idea of setting up a fleet of vans as minilabs to travel around China to test medicines?
Counterfeit medicines are a major public health risk for all communities. The phenomenon has grown in recent years due to counterfeiting methods becoming more sophisticated and counterfeit products looking so similar to the genuine product that they deceive health professionals as well as patients.
Eliminating them is a considerable public health challenge. In China, as everywhere in the world, counterfeit medicines and substandard drugs are mainly occurring in the rural areas where drug administration is weak since the institutes for drug quality control are located in urban areas. In order to combat the counterfeits and to protect the health of people living in rural areas, under the instruction of the State Food and Drug Administration (SFDA), the National Institute for the Control of Pharmaceutical and Biological Products (NICPBP) developed mobile labs for field testing.
How many vans and people do you now have on your team?
We now have nearly 400 mobile labs up and running in China. There are usually two to four people working in the van. By the end of 2009 over 310,000 had been visited and about one million batches of samples had been screened.
What role does technology play in addressing the issue of counterfeit medicines in China?
The scientific equipment in a mobile lab includes an NIR (near-infrared) spectrometer, TLC (Thin-Layer Chromotography) equipment, colorimeter, digital photography, visible microscopy and various test kits for specific chemical reactions.
The main screening tool in the mobile lab is based on an NIR spectrometer and a pre-developed, standard library of NIR spectra of selected, commonly used pharmaceutical products in China.
And, the all-important question really, do you think this initiative is having an impact?
Yes, I do believe we are having an impact. The mobile labs have played a very important role in some emergency response situations such as the Wuncui earthquake disaster in May 2008, when all district drug control labs were destroyed. One key sign that the programme has been deemed a success is that it is being expanded.
What are the future plans for the programme?
As I mentioned earlier, the programme is to be expanded into the development of a second generation of mobile laboratories, which is currently being developed. This second generation of minilabs will incorporate a patented green High-Performance Liquid Chromotography (HPLC) system that is suitable for mobile operation.
The key to this new HPLC system is that the solvents are close-loop recycled inside the van. And the advantage of implementing the HPLC system in the mobile lab is that if a drug product is suspected as counterfeit by an NIR screening method then an on-site confirmation can be performed by HPLC immediately in the van.
