Valstar

A drug used to treat bladder carcinoma in situ that did not get better after treatment with bacillus Calmette-Guerin (BCG). It is used in patients who cannot have surgery right away to remove all or part of the bladder. Valstar is given as a solution through a catheter that is placed into the bladder. It blocks a certain enzyme needed for cell division and DNA repair, and it may kill cancer cells. Valstar is a type of anthracycline antibiotic and a type of topoisomerase inhibitor. Also called AD 32 and valrubicin.
