Researchers at the University of Waterloo used computer-simulated drug trials to model the interactions of the three drugs- diuretics, renin-angiotensin (RSA) and ibuprofen and their impact on the kidney. They found that in people with certain medical profiles, the combination can cause acute kidney injury, which in some cases can be permanent. Diuretics and RSA inhibitors are commonly prescribed together for people with hypertension and are available under various pharmaceutical brand names. Painkillers such as ibuprofen are available over-the-counter in most pharmacies and stores in popular brands.
"It's not that everyone who happens to take this combination of drugs is going to have problems," said Anita Layton, professor of applied mathematics at Waterloo and Canada 150 Research Chair in mathematical biology and medicine. "But the research shows it's enough of a problem that you should exercise caution." Computer-simulated drug trials can quickly produce results that would take much longer in human clinical trials. Layton and her team use mathematics and computer science to give medical practitioners a head start with issues like drug complications.
