Recurrence of biliary drug lithiasis due to dipyridamole.

The occurrence of drug-containing gallstones is not often observed. To our knowledge, three drugs have so far been incriminated-ceftriaxone, glaphenine, and dipyridamole. This report presents the case of an 85-year-old woman who developed a recurrent drug-containing gallstone caused by dipyridamole eighteen months after a previous stone had been removed endoscopically.
