nausea, vomiting, diarrhea; mouth sores; rectal pain or sores; rash; or.

Which phase is affected by cytarabine?

Cytarabine is cytotoxic to a wide variety of proliferating mammalian cells in culture. It exhibits cell phase specificity, primarily killing cells undergoing DNA synthesis (S-phase) and under certain conditions blocking the progression of cells from the G1 phase to the S-phase.

How does cytarabine affect the skin?

Skin changes Cytarabine can cause a rash, which may be itchy. It may also cause your skin to become red or blistered. Always tell your doctor or nurse about any skin changes. They can give you advice and may prescribe creams or medicines to help.

How is cytarabine cleared?

It has an active metabolite- azacytidine triphosphate; and an inactive metabolite- uracil arabinoside, which is cleared by the kidney.

How toxic is cytarabine?

The main toxic effect of cytarabine injection is bone marrow suppression with leukopenia, thrombocytopenia and anemia. Less serious toxicity includes nausea, vomiting, diarrhea and abdominal pain, oral ulceration, and hepatic dysfunction.

Which phase of the cell is most affected by cytarabine?

Its mode of action is due to its rapid conversion into cytosine arabinoside triphosphate, which damages DNA when the cell cycle holds in the S phase (synthesis of DNA). Rapidly dividing cells, which require DNA replication for mitosis, are therefore most affected.

The main toxic effect of cytarabine is bone marrow suppression with leukopenia, thrombocytopenia, anaemia, megaloblastosis and reduced reticulocytes.

Can cytarabine cause fever?

Fever may occur when cytarabine is given and within 24 hours afterward. Eye drops may ease conjunctivitis and are given with high doses of cytarabine. Children have more problems with vomiting after intrathecal cytarabine than after intrathecal methotrexate.

Can cytarabine cause neuropathy?

Intravenous (IV) therapy may cause a peripheral neuropathy that varies greatly in its severity. The high IV cytarabine doses now commonly used can cause seizures, cerebral dysfunction, or an acute cerebellar syndrome with an incidence up to 14%.

What is cerebellar toxicity?

Cerebellar toxicity is a dose-dependent secondary effect of cytarabine; high doses of this drug are therefore linked to the greatest risk of developing this syndrome.

Why do you have to flush the toilet twice after chemo?

Small amounts of chemotherapy are present in your body fluids and body waste. If any part of your body is exposed to any body fluids or wastes, wash the exposed area with soap and water. People in your household may use the same toilet as you, as long as you flush all waste down the toilet twice with the lid down.

Kissing is a wonderful way to maintain closeness with those you love and is usually okay. However, during chemotherapy and for a short time afterward, avoid open-mouth kissing where saliva is exchanged because your saliva may contain chemotherapy drugs.

Is cytarabine a neurotoxic?

Neurotoxicity from high-dose cytarabine, a pyrimidine metabolite used in treatment for acute myeloid leukemia, is a known but dose-limiting toxicity which has incidences in up to 14% in patients receiving high doses of the drug.

Can cytarabine be given at home?

Cytarabine by subcutaneous injection is not given as frequently as intravenous but is a route of administration of Cytarabine in the home environment.

Does cytarabine cause myelosuppression?

Hematologic The main adverse effect of cytarabine is myelosuppression, and grade 3/4 toxicity occurs in virtually all patients treated with cytarabine-based regimens as part of induction therapy for acute myeloid leukemia. Infection is also extremely common and affects more than 60% of patients.

What drug class is cytarabine?

Does repair happen in mitosis?

Cells do not repair damage to DNA during mitosis because telomeres could fuse together. Summary: Throughout a cell’s life, corrective mechanisms act to repair DNA strand breaks. The exception is during the critical moment of cell division, when chromosomes are most vulnerable.

How does cytarabine prevent replication?

Cytarabine Prevent Replication DNA polymerases form DNA molecules by inserting deoxyribonucleotides into the primer that are complementary to the nucleotide bases, found in the single DNA strand template. It subsequently makes a DNA sequence complementary to the DNA strand used as a template.

What is metaphase?

Metaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes. … During this stage, the nucleus disappears and the chromosomes appear in the cytoplasm of the cell. During this stage in human cells, the chromosomes then become visible under the microscope.
