TABLOID SUMMARY
PRESCRIBING INFORMATION
TABLOID®
brand Thioguanine
40-mg Scored Tablets
TABLOID brand Thioguanine was synthesized and developed by Hitchings, Elion, and associates at the Wellcome Research Laboratories. It is one of a large series of purine analogues which interfere with nucleic acid biosynthesis, and has been found active against selected human neoplastic diseases.
- Acute Nonlymphocytic Leukemias: TABLOID brand Thioguanine is indicated for remission induction, remission consolidation, and maintenance therapy of acute nonlymphocytic leukemias. The response to this agent depends upon the age of the patient (younger patients faring better than older) and whether thioguanine is used in previously treated or previously untreated patients. Reliance upon thioguanine alone is seldom justified for initial remission induction of acute nonlymphocytic leukemias because combination chemotherapy including thioguanine results in more frequent remission induction and longer duration of remission than thioguanine alone.
- Other Neoplasms: TABLOID brand Thioguanine is not effective in chronic lymphocytic leukemia, Hodgkin's lymphoma, multiple myeloma, or solid tumors. Although thioguanine is one of several agents with activity in the treatment of the chronic phase of chronic myelogenous leukemia, more objective responses are observed with MYLERAN® (busulfan), and therefore busulfan is usually regarded as the preferred drug.
