Использование

Mitoxantrone is a DNA intercalating drug. Mitoxantrone inhibits DNA synthesis. Mitoxantrone is used as an anti-cancer agent.

Показания

Mitoxantrone (Novantrone) is a synthetic anthraquinone that is structurally and mechanistically related to the anthracyclines. It intercalates with DNA and produces single- strand DNA breakage. It is cross-resistant with doxorubicin in multidrug-resistant cells and in patients who have failed to respond to doxorubicin therapy.
Mitoxantrone is active against breast carcinomas, leukemias, and lymphomas. Its antitumor efficacy in patients with breast cancer is slightly lower than that of doxorubicin. Its major toxicity is myelosuppression; mucositis and diarrhea also may occur. Mitoxantrone produces less nausea, alopecia, and cardiac toxicity than does doxorubicin.

Механизм действия

The mechanism of its action is not completely understood, although it is presumed, that mitoxantrone acts by binding with DNA, thus disturbing the twisting process of the chains. It is used intravenously for treating severe nonlymphatic leukemia, breast cancer, and so on. A synonym of this drug is novantrone.
