Teniposido

Teniposido Uses, Dosage, Side Effects, Food Interaction and all others data.

Teniposido is a semisynthetic derivative of podophyllotoxin that exhibits antitumor activity. Teniposido inhibits DNA synthesis by forming a complex with topoisomerase II and DNA. This complex induces breaks in double stranded DNA and prevents repair by topoisomerase II binding. Accumulated breaks in DNA prevent cells from entering into the mitotic phase of the cell cycle, and lead to cell death. Teniposido acts primarily in the G2 and S phases of the cycle.

Teniposido is a phase-specific cytotoxic drug, acting in the late S or early G 2 phase of the cell cycle. Teniposido prevents cell mitosis by causing single and double stranded DNA breaks as well as cross linking between protein and DNA.

Uses

Teniposido is a cytotoxic drug used as an adjunct for chemotherapy induction in the treatment of refractory childhood acute lymphoblastic leukemia.

Teniposido is used for the treatment of refractory acute lymphoblastic leukaemia

Teniposido is also used to associated treatment for these conditions: Acute Lymphoblastic Leukaemia Recurrent, Mild Atopic dermatitis, Moderate Atopic dermatitis, Refractory Atopic dermatitis

How Teniposido works

The mechanism of action appears to be related to the inhibition of type II topoisomerase activity since teniposide does not intercalate into DNA or bind strongly to DNA. Teniposido binds to and inhibits DNA topoisomerase II. The cytotoxic effects of teniposide are related to the relative number of double-stranded DNA breaks produced in cells, which are a reflection of the stabilization of a topoisomerase II-DNA intermediate.

Food Interaction

Exercise caution with grapefruit products. Teniposido is a CYP3A4 substrate, and grapefruit inhibits CYP3A4 metabolism, coadministration may increase the serum concentrations of teniposide.
Exercise caution with St. John's Wort. Teniposido is a CYP3A4 substrate, and St. John's Wort induces CYP3A4 metabolism, coadministration may reduce the serum concentrations of teniposide.

Teniposido Disease Interaction

Major: infections, myelosuppressionModerate: hepatic dysfunction, renal dysfunction

Half Life

5 hours

Clearance

10.3 mL/min/m2

Elimination Route

From 4% to 12% of a dose is excreted in urine as parent drug. Fecal excretion of radioactivity within 72 hours after dosing accounted for 0% to 10% of the dose.
