The list of drugs that prolong the QT interval and cause torsades de pointes

is growing so rapidly that clinicians need help in keeping up. Here’s a useful resource: The Center for Education and Research on Therapeutics at the University of Arizona Health Sciences Center, spearheaded by Raymond L. Woosley, MD, PhD Vice President for Health Sciences there. Dr. Woosley has an extensive background on the clinical pharmacology of antiarrhythmic drugs. The site is a frequently updated listing of drugs that cause or increase the risk of TDP. The lists are categorized according to degree of risk and strength of recommendation.
