Cytabin Introduction
Cytabin is an anti-cancer chemotherapy drug. It is classified as an antimetabolite, as it works by preventing cells from producing new DNA strands that are needed for reproduction and division. It is most commonly used in the treatment of acute leukemias. It is a cytotoxic drug, meaning it begins to kill rapidly dividing cells such as cancer cells. While it is used to treat cancer, it could also potentially be used to treat other conditions that involve abnormal divisions, such as skin disorders or viral infections.
Uses for Cytabin
Cytabin is primarily used to treat acute leukemias, such as acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL). It can also be used to treat certain types of myelodysplastic syndromes, non-Hodgkin’s lymphoma, and other types of cancer. Cytabin may also be used in other cases where cells are rapidly dividing, such as viral infections or skin disorders.
Mechanism of Action
Cytabin works by inhibiting the enzymes that are responsible for producing DNA strands, which are required for cells to replicate and divide. This prevents the cancer cells from dividing, which eventually leads to their death. Cytabin is also able to penetrate into healthy cells, which allows it to treat multiple types of cancer and other conditions.
How Long Does It Take to Work?
