—Dr Soll1 states that ranitidine plus bismuth subcitrate has received preliminary approval from the FDA. To clarify his comments, the product Soll refers to is ranitidine bismuth citrate (Tritec), which is a novel salt of ranitidine with a complex of bismuth and citrate developed by Glaxo Wellcome. Ranitidine bismuth citrate, when used in conjunction with clarithromycin, has been recommended for approval by the joint Anti-infective and Gastrointestinal Drugs Advisory committees of the FDA.Several studies reviewed by the FDA committees to support this recommendation showed ranitidine bismuth citrate plus clarithromycin was well tolerated and eradicated H pylori infection in 82% to 94% of patients.2-4 These trials employed rigorous testing methods to ascertain the presence of infection and to confirm the eradication of infection. To be confirmed as being infected with H pylori, patients had to have at least 2 different positive diagnostic tests performed by central laboratory personnel
