Endoxan 200 mg/vial IV Infusion

Endoxan 200 mg/vial IV Infusion Uses, Dosage, Side Effects, Food Interaction and all others data.

Endoxan 200 mg/vial IV Infusion is a prodrug which is converted in the body to the active metabolites. It acts at any stage of the cell cycle. It prevents cell division by cross-linking deoxyribonucleic acid (DNA) strands and reducing DNA synthesis. It also exerts a potent immunosuppressive effect.

Endoxan 200 mg/vial IV Infusion is an antineoplastic in the class of alkylating agents and is used to treat various forms of cancer. Alkylating agents are so named because of their ability to add alkyl groups to many electronegative groups under conditions present in cells. They stop tumor growth by cross-linking guanine bases in DNA double-helix strands - directly attacking DNA. This makes the strands unable to uncoil and separate. As this is necessary in DNA replication, the cells can no longer divide. In addition, these drugs add methyl or other alkyl groups onto molecules where they do not belong which in turn inhibits their correct utilization by base pairing and causes a miscoding of DNA. Alkylating agents are cell cycle-nonspecific. Alkylating agents work by three different mechanisms all of which achieve the same end result - disruption of DNA function and cell death.

Uses

Malignant Diseases:

Endoxan 200 mg/vial IV Infusion is used for the treatment of:

  • Malignant lymphomas (Stages III and IV of the Ann Arbor staging system), Hodgkin's disease, lymphocytic lymphoma (nodular or diffuse), mixed-cell type lymphoma, histiocytic lymphoma, Burkitt's lymphoma
  • Multiple myeloma
  • Leukemias: chronic lymphocytic leukemia, chronic granulocytic leukemia (it is usually ineffective in acute blastic crisis), acute myelogenousand monocytic leukemia, acute lymphoblastic (stem-cell) leukemia (cyclophosphamide given during remission is effective in prolonging its duration)
  • Mycosis fungoides (advanced disease)
  • Neuroblastoma (disseminated disease)
  • Adenocarcinoma of the ovary
  • Retinoblastoma
  • Carcinoma of the breast

Endoxan 200 mg/vial IV Infusion, although effective alone in susceptible malignancies, is more frequently used concurrently or sequentially with other antineoplastic drugs.

Minimal Change Nephrotic Syndrome in Pediatric Patients:

Endoxan 200 mg/vial IV Infusion is used for the treatment of biopsy proven minimal change nephrotic syndrome in pediatrics patients who failed to adequately respond to or are unable to tolerate adrenocorticosteroid therapy.

Endoxan 200 mg/vial IV Infusion is also used to associated treatment for these conditions: Acute Lymphoblastic Leukaemias (ALL), Acute Myelocytic Leukemia, Adenocarcinoma of the Ovaries, Autoimmune Hemolytic Anemia, Breast Cancer, Burkitt's Lymphoma, Chronic Lymphocytic Leukaemia (CLL), Chronic Myeloid Leukemia (CML), Disseminated Neuroblastoma, Ewing's Sarcoma, Granulomatosis With Polyangiitis, Juvenile Idiopathic Arthritis (JIA), Lung Cancers, Lymphoma, Hodgkins, Minimal Change Nephrotic Syndrome (MCNS), Multiple Myeloma (MM), Myasthenia Gravis, Nephritis, Lupus, Non-Hodgkin's Lymphoma (NHL), Ovarian germ cell tumour, Pheochromocytomas, Retinoblastoma, Rhabdomyosarcomas, Uveitis, Waldenström's Macroglobulinemia (WM), Advanced Alibert-Bazin syndrome, Histiocytic lymphoma, Metastatic gestational trophoblastic tumor, Mixed-cell type lymphoma, Recurrent Pericarditis, Refractory Small cell lung cancer, Refractory immune thrombocytopenia, Relapsed Wilm's tumor, Conditioning regimens for allogeneic stem cell transplantation therapy

How Endoxan 200 mg/vial IV Infusion works

Alkylating agents work by three different mechanisms: 1) attachment of alkyl groups to DNA bases, resulting in the DNA being fragmented by repair enzymes in their attempts to replace the alkylated bases, preventing DNA synthesis and RNA transcription from the affected DNA, 2) DNA damage via the formation of cross-links (bonds between atoms in the DNA) which prevents DNA from being separated for synthesis or transcription, and 3) the induction of mispairing of the nucleotides leading to mutations.

Dosage

Endoxan 200 mg/vial IV Infusion dosage

Precaution

Patient with DM, severe immunosuppression, acute porphyria, pre-existing CV disease or those at risk for cardiotoxicity. Renal and hepatic impairment. Lactation.

Interaction

Increased risk of cardiotoxicity with doxorubicin or other cardiotoxic drugs. May increase incidence of mucositis with protease inhibitors.

May result to acute encephalopathy with metronidazole. May increase risk of thromboembolic complications. May alter the effect of warfarin. May increase immunosuppressive effect of ciclosporin. May result to prolonged apnoea with depolarising muscle relaxants (e.g. suxamethonium).

Food Interaction

  • Drink plenty of fluids. Drink 2 to 3 liters of fluids a day.
  • Take with food. Food reduces irritation.

Elimination Route

After oral administration, peak concentrations occur at one hour.

Half Life

3-12 hours

Clearance

Total body clearance = 63 ± 7.6 L/kg.

Elimination Route

Endoxan 200 mg/vial IV Infusion is eliminated primarily in the form of metabolites. 10-20% is excreted unchanged in the urine and 4% is excreted in the bile following IV administration.

Pregnancy & Breastfeeding use
