Paper Analytical Device Project

A comment just published in Lancet Global Health expresses concern for the whole global supply chain due to the COVID-19 pandemic.  M. Lieberman is one of the 53 co-authors.  The comment urges the global community not to loose track of the need to provide access to good quality medical products for all the other illnesses out there.  Already, the epidemic is limiting mass gatherings for medical treatments such as vaccination, creating intense demand for drugs without a good evidence base for use in COVID-19, and curtailing regulatory efforts such as post-market surveillance. …

Paper Millifluidics Lab: Using a Library of Color Tests to Find Adulterated Antibiotics

A two to three period analytical chemistry experiment has been developed which allows second year students to explore chemical color tests used to detect adulterated pharmaceuticals. Students prepare several paper analytical devices (PADs) to generate positive and negative controls antibiotics, along with cutting agents such as starch and chalk. These PADs are used to identify the active ingredients and excipients in mystery tablets prepared by their classmates. In the second part of the lab, the students select an individual color test and design an experiment to quantify their mystery pill’s active pharmaceutical ingredient (API). Nearly all the student groups were able to successfully identify adulterants present in their mystery tablets.  The quantification of the mystery tablets was also successful with all but one group calculating the correct concentration within 6%. In a post-lab assessment, the students identified their largest gains in their ability to analyze data and other information, skill in science writing, and learning of laboratory techniques.…

Every person has the right to receive safe, quality medical products – but all too often, this isn’t the case.

• Poor-quality medical products (including medicines, vaccines, biologics and diagnostics) fall into two categories: substandard or falsified. Both negate the benefits of modern health care and put patients at risk.

Congratulations to Sarah Bliese, whose paper on analysis of ceftriaxone via the 12-lane PAD was just accepted in Analytical Methods.  Sarah used principal component analysis (PCA) to differentiate good and bad products and even to figure out why a given product was bad quality.  

Color "bar codes" classify the products as good or bad.…

Nick Meyers' paper on quantitative analysis of beta lactams on a paper card was just accepted by Analytical Methods.  Congratulations Nick! The aPAD accuracy is about 5%, not quite as good as an HPLC, but then again, the aPAD doesn't cost $40,000.  

The more blue dots appear, the smaller the antibiotic content.…

The Disease Diagnostic INventors Challenge provides funding to focus measurement science and engineering creativity at Purdue, IU, IBRI and Notre Dame on innovations with the potential to address unmet biomedical needs. Kathleen Hayes and Vincent Schmitz brought together the research strengths of the Whalen and Lieberman groups at Notre Dame to tackle the difficult task of detecting bad quality or fake oxytocin.  There is currently no field test available for oxytocin quality, and studies show that about 1 in 4 vials dispensed to women in Africa do not meet quality standards.  Good luck to these energetic first year grad students!…

Marya Lieberman gave a workshop about post-market surveillance for 40 staff members from the Directorate General of Drug Administration in Dhaka, Bangladesh, the National Control Lab, and WHO-PQM. 

The workshop included a fun project to evaluate the supply chain of a medicine which involved 28 neophytes analyzing samples from a fictional country.  The PAD reader box also made its first debut outside Notre Dame.  This smart PAD reader will be sited in Bandarban at the icddr,b field office, where a small sampling project will be based in 2019.    …

ASTMH Journal has a good review of policy options for combatting  falsified and substandard medicines--link here. 

Abstract:  Falsified and substandard medicines are associated with tens of thousands of deaths, mainly in young children in poor countries. Poor-quality drugs exact an annual economic toll of up to US$200 billion and contribute to the increasing peril of antimicrobial resistance. The WHO has emerged recently as the global leader in the battle against poor-quality drugs, and pharmaceutical companies have increased their roles in assuring the integrity of drug supply chains. Despite advances in drug quality surveillance and detection technology, more efforts are urgently required in research, policy, and field monitoring to halt the pandemic of bad drugs. In addition to strengthening international and national pharmaceutical governance, in part by national implementation of the Model Law on Medicines and Crime, a quantifiable Sustainable Development Goal target and an international convention to insure drug quality and safety are urgent priorities.…
