Doxorubicine Introduction

Doxorubicine is a type of chemotherapy drug used to treat cancerous tumors. It belongs to the family of drugs called anthracyclines and is a part of the larger group of drugs called antineoplastics. Doxorubicine works by damaging cancer cells so that they can no longer grow and replicate. It also interferes with the cancer cells’ ability to repair itself, which can weaken them and cause them to die.

Uses for Doxorubicine

Doxorubicine is used to treat numerous types of cancers, including:

• Acute myeloid leukemia (AML)
• Chronic myeloid leukemia (CML)
• Breast cancer
• Lung cancer
• Gastric (stomach) cancer
• Ovarian cancer
• Hodgkins lymphoma

Mechanism of Action

Doxorubicine works by attacking the DNA of cancer cells. It binds to a specific site in the cancer cell’s DNA called the topoisomerase 2 site, which interferes with the cancer cell’s ability to replicate. Without being able to replicate, the cancer cells are destroyed.

How long does it take to work?
