Azacitidine belongs to the class of hypomethylating agents and is classified as a cytotoxic drug; that means it works to interfere with the growth of abnormal cells. Specifically, Azacitidine operates by inhibiting the methylation process within DNA on cancer cells.
Methylation is a biochemical process used to silence genes that potentially act as tumor suppressors. In theory, by stopping this methylation process, the silenced tumor suppressor genes are now reactivated; hence there is the elimination of aberrant cells through their deaths.
Azacitidine is administered typically under the supervision of a health care provider in a clinical setting but may eventually be taken by a patient when stable to administer himself at home. The medicine is commonly given through subcutaneous injection but could also be given by IV infusion.
Subcutaneous Injection:
Preparation: The injection must be given once daily for 7 days in a 28-day cycle for patients with MDS. For AML, a different regimen may be used.
Injections are given subcutaneously and are usually provided in areas such as the abdomen or thigh. However, alternate sites must be used for each injection.
Administration: An injection should be demonstrated for the patient by a healthcare professional, or the patient is taught how to administer his or her own injections.
Cycle: Azacitidine is usually administered in a cyclic regimen. Treatment periods are followed by rest periods to allow the body to recover and respond.
Intravenous (IV) Infusion:
When administered intravenously, Azacitidine is usually infused over several hours.
This is usually done in a hospital or outpatient clinic setting.
It is important to follow the prescribed regimen exactly as recommended by your healthcare provider. Missing doses or altering the dosage can affect the treatment’s effectiveness.
The primary mechanism of action of Azacitidine is through its inhibition of DNA methylation, a process by which gene expression is regulated. Here’s how Azacitidine works,
DNA Methylation Inhibition: Azacitidine is incorporated into the DNA of dividing cells, where it interferes with DNA methyltransferase enzymes that add methyl groups to DNA. These methyl groups are often added to tumor suppressor genes, silencing their expression. In cancer cells, this silencing can allow for uncontrolled growth.
Reactivation of Suppressor Tumor Genes : This is through the blockage of DNA methylation of gene silencing of tumor suppressors genes, which then proceeds to regulate the growth and expansion of cancer cells.
Disturbance of cell cycle: Azacitidine causes disturbance in the cell cycle through bringing about apoptosis in diseased cells, especially those possessing dysfunctional or mutated DNA sequences.
Induction of Differentiation: In myelodysplastic syndromes (MDS), Azacitidine induces the maturation of abnormal blood cells, which may lead to an improvement in blood counts and reduction in symptoms of the disease.
Even though Azacitidine is tolerable, it does induce side effects. Among these, the most common include:
Injection Site Reactions: Redness, swelling, or pain at the injection site.
Low Blood Counts: Azacitidine can cause a drop in white blood cells count (neutropenia), red blood cells count (anemia), and platelet count (thrombocytopenia), which may cause infection, fatigue, and bleeding.
Nausea and Vomiting: Gastrointestinal side effects are common and may include nausea, vomiting, or diarrhea.
Fatigue: Patients may experience fatigue, which is often related to low blood cell counts or the drug’s effects on the body.
Fever and Flu-like Symptoms: Some patients experience flu-like symptoms such as fever, chills, or body aches.
Liver Dysfunction: Azacitidine may affect liver function, so liver enzymes should be monitored during treatment.
Bone Marrow Suppression: Azacitidine causes bone marrow suppression. Blood counts should be checked regularly during treatment.
Infections: Immunosuppressive effects of azacitidine can cause infections. Patients must be monitored for signs of infection and can be treated with antibiotics or other drugs as a prophylactic measure.
Pregnancy and Breastfeeding: Azacitidine is contraindicated in pregnancy, as it can harm the fetus. It is not recommended in breastfeeding also. Women of childbearing age must practice effective contraception during treatment.
Liver Function: Azacitidine can influence liver function. The liver function tests should be performed frequently during the treatment period.
Always consult with a healthcare provider before combining treatments.
The dosage of Azacitidine depends on the condition of the patient, the age, and general well-being. Typical dosages for MDS and AML are given in 7-day cycles and administered subcutaneously or intravenously. For instance, a standard MDS dose may be 75 mg/m²/day for 7 days and repeated every 28 days. The actual dose and schedule will be decided by the prescribing doctor.
Azacitidine is prescribed medication and should be prescribed by a healthcare provider as well. It comes either in the form of injection, subcutaneous and intravenous infusion, and the appropriate use of it will be assessed by a healthcare provider depending upon the patient’s condition.
Answer: Azacitidine is a medication used to treat certain types of blood disorders, primarily myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML). It is a type of chemotherapy that works as a hypomethylating agent, which helps restore normal cell function.
Answer: Azacitidine works by inhibiting DNA methyltransferases, leading to the demethylation of DNA. This process can reactivate genes that are silenced in cancer cells, promoting normal cell growth and differentiation.
Answer: Azacitidine is primarily used to treat myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML). It can also be used in patients with chronic myelomonocytic leukemia (CMML).
Answer: Azacitidine can be administered through subcutaneous injection or intravenous infusion. The route of administration depends on the patient’s condition and treatment plan.
Answer: The dosage of Azacitidine varies based on the condition being treated and the patient’s overall health. Typically, it is given in cycles, often as 75 mg/m² per day for 7 days, repeated every 28 days.
Answer: Common side effects include low blood cell counts (leading to anemia, increased risk of infections, and bleeding), nausea, vomiting, diarrhea, fatigue, and potential injection site reactions.
Answer: Yes, serious side effects can occur, such as severe allergic reactions, liver problems, and signs of infection. Patients should be monitored closely during treatment.
