Generic Name: Valrubicin (VAL-roo-bi-sin)
Trade Name: Valstar®
How is this drug used? Valrubicin is FDA approved for the treatment of patients with superficial bladder cancer that has stopped responding to BCG therapy, and in whom an immediate cystectomy (removal of the bladder) would cause unacceptable side effects. It is important for patients to remember that physicians have the ability to prescribe medication for conditions other than those for which the drug has been approved by the FDA. Patients who have received a prescription of this drug for a condition other than which it is approved may wish to discuss this issue with their physician.
What is the mechanism of action? Valrubicin belongs to a class of drugs called anthracycline antitumor antibiotics. An anti-tumor antibiotic produces its anti-cancer effects by binding to DNA and inhibiting the production of proteins necessary for sustaining life of a cell.
How is valrubicin given (administered)? Valrubicin is administered directly into the bladder and the dose depends on several factors, including the condition being treated, the size of the patient, the particular regimen being used and the overall health of the patient. The valrubicin is retained in the bladder for 2 hours then voided.
How are patients monitored? Patients will usually have scheduled meetings with their healthcare provider while they are being treated with valrubicin. Patients may also undergo physical examinations, scans or other measures to assess side effects and response to therapy. Patients will also be monitored for urinary tract infections and will receive follow-up cystoscopies.
