Teniposide - Uses, Dose, Side effects

Teniposide is a chemotherapeutic medicine (anti-cancer medicine) that is classified as "Topoisomerase inhibitor".

Indications of Teniposide:

  • Refractory Acute lymphoblastic leukemia:

    • It is used for the treatment of refractory childhood acute lymphoblastic leukemia in combination with other chemotherapy.
  • Off Label Use of Teniposide in Adults:

    • Acute lymphoblastic leukemia

Teniposide Dose in Adults

Note: First cycle should be given at half the actual dose to patients with Down syndrome and leukemia due to more incidence of myelosuppression.

Teniposide dose in the treatment of Acute lymphoblastic leukemia (consolidation treatment in combination chemotherapy):

  • 165 mg/m² intravenous on days 1, 4, 8, and 11 of alternating consolidation cycle

Teniposide Dose in Childrens

Teniposide dose in the treatment of Acute lymphoblastic leukemia (combination therapy):

  • Infants ≥6 months, Children, and Adolescents:

    • Regimens may vary: 165 mg/m² intravenous twice weekly for 8 to 9 doses or 250 mg/m weekly for 4 to 8 weeks

Teniposide dose in the treatment of high-risk Neuroblastoma:

  • Children and Adolescents:

    • 100 mg/m² intravenous administered 48 hours after completion of a 6 hour cisplatin infusion dose every 3 weeks.

Pregnancy Risk Category: D

  • Studies on animal reproduction revealed that there were adverse effects.
  • Teniposide can cause harm to the fetus so it is best to avoid it during pregnancy.

Use while breastfeeding

Warnings and precautions

  • Suppression of bone marrow: [US Boxed Warning]

    • It can lead to severe myelosuppression, which can result in fatal infections or bleeding. Therefore, it is important to monitor blood counts.
  • Extravasation

    • It is an irritant. It is important to position the catheter/needle correctly as it can cause tissue necrosis or thrombophlebitis (if extravasation occurs).
  • Hypersensitivity [US Boxed Warning]

    • Hypersensitivity reactions include anaphylaxis and bronchospasm as well as dyspnea.
    • It is important to stop the infusion immediately and give treatment with Epinephrine with or without antihistamines and corticosteroids.
    • If there is a history of hypersensitivity in the past, recurrences are common. Premedication with antihistamines and corticosteroids is advised.
  • Hypotension

    • Hypotension can result. Slow infusion for at least 30-60 minutes should be avoided.
  • High doses can cause toxicities

    • CNS depression and metabolic acidosis are more common when the drug is administered in high doses or combined with antiemetics.

Monitoring parameters:

  • Blood pressure

  • Monitor for hypersensitivity reaction

How to administer Teniposide?

  • Before and after each infusion, the infusion line should always be cleaned with normal saline. 
  • You should administer it by slow intravenous injection over half an hour to one hour using non-DEHP-containing sets.
  • Close monitoring for hypotension should be performed. To prevent precipitation, it should be administered immediately after preparation.
  • In case of anaphylaxis, the infusion should be stopped immediately and treated with Epinephrine or corticosteroids.
  • It contains N, N–dimethylacetamide.
  • This may make it incompatible with closed-system transfer devices whose plastic content may dissolve, resulting in leakage or possible infusion of dissolved material into the patient.

Mechanism of action of Teniposide:

  • It acts as a topoisomerase-2 inhibitor. 
  • It delays the transit of cells through S phase and arrests cells in late S/early G phase to prevent them from entering mitosis.
  • It prevents DNA ligase and strand passing, resulting in DNA strand breakage.

Protein binding: is greater than 99% (primarily to albumin)

Metabolism: Extensively occurs in the liver.

Half-life elimination: Children: 5 hours

Excretion: Urine (44%, 4% to 12% as unchanged drug); feces (≤10%)
