• Uses: It is used as anti-cancer drug mainly used for the treatment of small cell lung cancer, testicular cancer, malignant lymphoma and acute leukemia. It also has certain efficacy in treating neuroblastoma, rhabdomyosarcoma, ovarian cancer, non-small cell lung cancer, stomach cancer and breast cancer. Etoposide is used for germinogenic tumors, ovarian, stomach, and lung cancer, Hodgkin’s disease, and non-Hodgkin’s lymphoma for both monotherapy and in combination therapy. An antitumur agent that complexes with topoisomerase II and DNA to enhance double-strand and single strand cleavage of DNA and reversible inhitit religation. Blocks the cell cycle in S-phase and G2-phase of the cell cycle. Induces apoptosis in nor A DNA topoisomerase II inhibitor. Semi-synthetic derivative of podophyllotoxin, related structurally to Teniposide. Antineoplastic. anticonvulsant
• Drug Interactions: 1. Because this product has significant bone marrow suppression effect and should be taken care of when be used in combination with other anticancer drugs. 2. This product can inhibit the body's immune defense mechanism, so that vaccination is not able to stimulate the body to produce antibodies. 3. Within 3 months after the end of chemotherapy, it is not recommended for applying the vaccine virus. 4. This product has a high binding rate to the plasma protein and therefore, the drug bound to plasma protein can affect the excretion of this product.
• Description: Etoposide is a plant alkaloid and an inhibitor of topoisomerase II (IC50 = 60.3 μM). It inhibits proliferation of a variety of adenocarcinoma cells (IC50s = 0.005-12,200 μM) and human umbilical vein endothelial (HUVEC) cells (IC50 = 0.249 μM). It reduces tumor growth in an Ma human embryonal carcinoma mouse xenograft model when administered at a dose of 25 mg/kg, an effect that is enhanced by concomitant administration of the immunosuppressant cyclosporin A . Etoposide also inhibits nuclear receptor coactivator 3 (IC50 = 2.48 μM). Formulations containing etoposide have been used in combination therapy in the treatment of cancer.
• Indications: Etoposide (VePesid) is a semisynthetic derivative of podophyllotoxin that is produced in the roots of the American mandrake, or May apple. Unlike podophyllotoxin and vinca alkaloids, etoposide does not bind to microtubules. It forms a complex with the enzyme topoisomerase II, which results in a single-strand breakage of DNA. It is most lethal to cells in the S- and G2-phases of the cell cycle. Drug resistance to etoposide is thought to be caused by decreased cellular drug accumulation. Etoposide is most useful against testicular and ovarian germ cell cancers, lymphomas, small cell lung cancers, and acute myelogenous and lymphoblastic leukemia.Toxicities include mild nausea, alopecia, allergic reaction, phlebitis at the injection site, and bone marrow toxicity.
• Therapeutic Function: Antitumor, Antineoplastic
• Clinical Use: Etoposide is utilized in the treatment of small cell lung cancer and in combination with other agents in refractory testicular cancer.
• Drug interactions: Potentially hazardous interactions with other drugs Anticoagulants: possibly enhanced anticoagulant effect with coumarins. Antipsychotics: avoid concomitant use with clozapine, increased risk of agranulocytosis. Ciclosporin: 50% reduction in etoposide clearance.
