- Accession Number
- DB00385
- Description
Valrubicin (N-trifluoroacetyladriamycin-14-valerate) is a chemotherapy drug commonly marketed under the trade name VALSTAR. It is a semisynthetic analog of the doxorubicin, which is an anthracycline drug. Used in the treatment of the bladder cancer, valrubicin is administered by direct infusion into the bladder.

- Pharmacodynamics
Valrubicin is an anticancer agent.
- Mechanism of action
Valrubicin is an anthracycline that affects a variety of inter-related biological functions, most of which involve nucleic acid metabolism. It readily penetrates into cells, where after DNA intercalation, it inhibits the incorporation of nucleosides into nucleic acids, causes extensive chromosomal damage, and arrests cell cycle in G2. Although valrubicin does not bind strongly to DNA, a principal mechanism of its action, mediated by valrubicin metabolites, is interference with the normal DNA breaking-resealing action of DNA topoisomerase II.

- Toxicity
The primary anticipated complications of overdosage associated with intravesical administration would be consistent with irritable bladder symptoms. Myelosuppression is possible if valrubicin is inadvertently administered systemically or if significant systemic exposure occurs following intravesical administration (e.g., in patients with bladder/rupture perforation). The maximum tolerated dose in humans by either intraperitoneal or intravenous administration is 600 mg/m2.
