Arsenic trioxide is an inorganic compound with the formula As 2 O 3. [5] As an industrial chemical, its major uses include the manufacture of wood preservatives, pesticides, and glass. [6] It is sold under the brand name Trisenox among others [2] [3] when used as a medication to treat a type of cancer known as acute promyelocytic leukemia. [7]
Arsenic trioxide is intended for the induction of remission and consolidation in adult patients with acute promyelocytic leukemia who have the t(15;17) translocation and/or the PML/RARα gene. The drug should be used after treatment failure or relapse. Prior therapy should include retinoid and chemotherapy. [70]
Arsenic trioxide (As 2 O 3) is currently being evaluated for treatment of relapsed/refractory disease. Remission with arsenic trioxide has been reported. [23] Studies have shown arsenic reorganizes nuclear bodies and degrades the mutant PML-RAR fusion protein. [23] Arsenic also increases caspase activity which then induces apoptosis. [23]
Acute promyelocytic leukemia (APL) used to be a dreaded disease, the most vicious of all acute leukaemias. Standard risk APL can now be cured in virtually all patients by a combination of a hormone, retinoic acid, and arsenic trioxide. The latter can even be substituted by tetra-arsenic tetra-sulphide, allowing oral therapy.
Arsenic trioxide (As 2 O 3) ... By contrast, arsenic oxide is an approved and effective chemotherapeutic drug for the treatment of acute promyelocytic leukemia (APL). [3]
Arsenic in its trioxide, As 2 O 3, (brand name Trisenox, ATO) is used as a chemotherapy drug against acute promyelocytic leukaemia (APL), a type of myeloid leukemia. [11] The detailed mechanism of action is unknown, but it is suspected to speed up apoptosis of cancer cells.
Arsenic trioxide [Note 2] IV: Not fully understood. Induces partial differentiation and promotes apoptosis of leukaemic cells and may also inhibit angiogenesis. Refractory or relapsed acute promyelocytic leukaemia.
