Valrubicin is the generic for the trade chemotherapy drug Valstar®. v
In some cases, health care professionals may use the trade name Valstar ®
when referring to the generic drug name Valrubicin.
Drug type: Valrubicin is an anti-cancer (“antineoplastic” or “cytotoxic”)
chemotherapy drug. Valrubicin is classified as an “anthracycline antiobiotic” (for
more detail, see "How this drug works," below).
What Valrubicin Is Used For:
- Valrubicin is for the treatment of bladder cancer.
Note: If a drug has been approved for one use, physicians may elect to use this
same drug for other problems if they believe it may be helpful.
How Valrubicin Is Given:
- Valrubicin is given by intravesical instillation. This means it is given directly
into the bladder through a urinary catheter. The bladder is emptied prior to instillation
of Valrubicin in to the bladder by voiding. The urinary catheter is inserted through
the urethra (the tube which carries urine from the bladder to the outside the body).
The Valrubicin solution is injected into the catheter and the catheter is then removed.
The patient is encouraged to roll from side to side and to lie on their backs to
help the medication reach all areas of the bladder.
- It is very important that the Valrubicin remains in the bladder for 2 hours before
- Valrubicin is given as an outpatient procedure at a cancer center, doctor’s office
- It is important to maintain adequate hydration with this medication.
Important things to remember about the side effects of Valrubicin:
- Most people do not experience all of the side effects listed.
- Side effects are often predictable in terms of their onset and duration.
- Side effects are almost always reversible and will go away after treatment is complete.
- There are many options to help minimize or prevent side effects.
- There is no relationship between the presence or severity of side effects and the
effectiveness of the medication.
- In general, local adverse reactions occur during or shortly after instillation and
resolve within 1-7 days.

Monitoring and Testing:
You will be checked regularly by your health care professional while you are taking
Valrubicin, to monitor side effects and check your response to therapy
How Valrubicin Works:
Cancerous tumors are characterized by cell division, which is no longer controlled
as it is in normal tissue. “Normal” cells stop dividing when they come into contact
with like cells, a mechanism known as contact inhibition. Cancerous cells lose this
ability. Cancer cells no longer have the normal checks and balances in place that
control and limit cell division. The process of cell division, whether normal or
cancerous cells, is through the cell cycle. The cell cycle goes from the resting
phase, through active growing phases, and then to mitosis (division).
The ability of chemotherapy to kill cancer cells depends on its ability to halt
cell division. Usually, the drugs work by damaging the RNA or DNA that tells the
cell how to copy itself in division. If the cells are unable to divide, they die.
The faster the cells are dividing, the more likely it is that chemotherapy will
kill the cells, causing the tumor to shrink. They also induce cell suicide (self-death
Chemotherapy drugs that affect cells only when they are dividing are called cell-cycle
specific. Chemotherapy drugs that affect cells when they are at rest are called
cell-cycle non-specific. The scheduling of chemotherapy is set based on the type
of cells, rate at which they divide, and the time at which a given drug is likely
to be effective. This is why chemotherapy is typically given in cycles.
Unfortunately, chemotherapy does not know the difference between the cancerous cells
and the normal cells. Chemotherapy will kill all cells that are rapidly dividing.
The “normal” cells will grow back and be healthy but in the meantime, side effects
Valrubicin is classified as an antitumor antibiotic. Antitumor antibiotics are made
from natural products produced by species of the soil fungus Streptomyces. These
drugs act during multiple phases of the cell cycle and are considered cell-cycle
specific. There are several types of antitumor antibiotics:
Anthracyclines: Valrubicin, Doxorubicin, Daunomycin, Mitoxantrone, and Idarubicin
Chromomycins: Dactinomycin and Plicamycin
Miscellaneous: Mitomycin and Bleomycin
