5-htp Overview

Valrubicin Overview
-
Valrubicin solution is used to treat a type of bladder cancer (carcinoma in situ; CIS) that was not effectively treated with another medication (Bacillus Calmette-Guerin; BCG therapy) in patients that can not have surgery right away to remove all or part of the bladder. However, only about 1 out of 5 patients responds to treatment with valrubicin and delaying bladder surgery may lead to the spread of bladder cancer which may be life-threatening. Valrubicin is an anthracycline antibiotic that is only used in cancer chemotherapy. It slows or stops the growth of cancer cells in your body.
