Pharmacologic Action:

   Cytarabine is a pyrimidine antimetabolite that mainly acts on cell S proliferation phase, and interferes with cell proliferation by inhibiting cellular DNA synthesis. After entering the body, cytarabine is phosphorylated by kinase and converted into cytarabine triphosphate and cytarabine diphosphate, the former of which strongly inhibits the synthesis of DNA polymerase, while the latter inhibits the conversion of cytarabine diphosphate into deoxycytidine diphosphate, thereby inhibiting cellular DNA polymerization and synthesis.


Product Usage:

   Cytarabine is mainly used in acute leukemia: it is most effective in acute granulocytic leukemia, and is also effective in acute monocytic leukemia and acute lymphoblastic leukemia. It is usually used in combination with other drugs. It is effective for malignant lymphoma, lung cancer, gastrointestinal tract cancer, head and neck cancer, and also for viral keratitis and epidemic conjunctivitis, etc.



Application Cases: 






Application Method:

   Cytarabine is a pyrimidine antimetabolite that acts as long as it acts in the proliferative phase of cells S. It is mainly used in acute myelogenous leukemia, acute lymphoid leukemia and lymphoma, and it is a central drug in the treatment of these diseases in the induction of chemotherapy.
Cytarabine has antiviral effects and is used to treat various herpes virus infections. However, due to its poor antiviral selectivity and its ability to cause myelosuppression and other serious adverse effects, cytarabine is still mainly used in malignant hematologic diseases. In addition, cytarabine has also been used in neurological studies to control the proliferation of glial cells.
