History

The Arizona Center for Education and Research on Therapeutics (AZCERT) maintains the CredibleMeds database. Founded in 2000 at the

University of Arizona The University of Arizona (Arizona, U of A, UArizona, or UA) is a public land-grant research university in Tucson, Arizona. Founded in 1885 by the 13th Arizona Territorial Legislature, it was the first university in the Arizona Territory. T ...

as part of a network of 14 federally-funded CERTs, AZCERT became a separate non-profit corporation in 2012 funded by the US Food and Drug Administration (FDA),

Adverse drug event analysis

AZCERT developed the Adverse Drug Event Causality Analysis (ADECA) to evaluate drugs for their risk of causing QT prolongation and TdP. As part of its ADECA reviews, AZCERT includes drugs marketed outside the

United States The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territori ...
