Also known as Seldane
Terfenadine was an antihistamine formerly used for the treatment of allergic conditions. It was brought to market by Hoechst Marion Roussel (now Sanofi-Aventis) and marketed under various brand names, including Seldane in the United States, Triludan in the United Kingdom, and Teldane in Australia. According to its manufacturer, terfenadine had been used by over 100 million patients worldwide as of 1990. It was superseded by fexofenadine in the 1990s due to the risk of a particular type of disruption of the electrical rhythms of the heart (specifically cardiac arrhythmia caused by QT interval prolongation).Source: Wikipedia
