Care During Chemotherapy and Beyond
Generic Name: Vorinostat
Zolinza is an anti-cancer ("antineoplastic" or "cytotoxic") chemotherapy drug. Zolinza
is classified as an "Histone Deacetylase Inhibitor". For more detail, see
How Zolinza Works below.
What Zolinza Is Used For:
Zolinza is used to treat relapsed or refractory cutaneous T-cell lymphoma (CTCL).
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 Zolinza Is Given:
The amount of Zolinza that you will receive depends on many factors, including your
general health or other health problems, and the type of cancer or condition you
have. Your doctor will determine your exact dosage and schedule.
Important things to remember about the side effects of Zolinza:
- Most people will not experience all of the Zolinza side effects listed.
- Zolinza side effects are often predictable in terms of their onset, duration, and
- Zolinza side effects are almost always reversible and will go away after therapy
- There is no relationship between the presence or severity of Zolinza side effects
and the effectiveness of the medication.
- Zolinza side effects may be quite manageable. There are many options to minimize
or prevent them.
The following Zolinza side effects are common (occurring in greater than 30%) for
patients taking Zolinza:
- Taste changes
- Increased blood glucose level (hyperglycemia)
- Increased creatinine level (transient)
- Increased level of protein in the urine
- Low platelet count (thrombocytopenia)
These are less common side effects (occurring in about 10-29%) of patients receiving
- Loss of appetite (anorexia)
- Weight loss
- Muscle spasms
- Hair loss (alopecia)
- Dry mouth
- Low red blood cell count (anemia)
- Swelling in hands or feet
- Upper respiratory infection
- Shortness of breath
A rare, but serious side effect of Zolinza is blood clots, including deep vein thrombosis
(DVT) and pulmonary embolus. You should seek emergency help and notify your
health care provider immediately if you develop sudden chest pain and shortness
of breath. Notify your health care provider within 24 hours if you notice
that one leg is swollen, red, painful and/or warm to touch and the other is not.
This list includes common and less common side effects for those taking Zolinza.
Zolinza side effects that are very rare -- occurring in less than about 10 percent
of patients -- are not listed here. But you should always inform your health care
provider if you experience any unusual symptoms.
When to contact your doctor or health care provider:
Contact your health care provider immediately, day or night, if you should experience
any of the following symptoms:
- Chest pain
- Sudden onset of shortness of breath
- Severe bleeding
The following symptoms require medical attention, but are not an emergency. Contact
your health care provider within 24 hours of noticing any of the following:
- Nausea (interferes with ability to eat and unrelieved with prescribed medication).
- Vomiting (vomiting more than 4-5 times in a 24 hour period).
- Diarrhea (4-6 episodes in a 24-hour period).
- Unusual bleeding or bruising
- Black or tarry stools, or blood in your stools.
- Blood in the urine.
- Pain or burning with urination.
- Extreme fatigue (unable to carry on self-care activities).
- Swelling, redness and/or pain in one leg or arm and not the other
- Unable to eat or drink for 24 hours or have signs of dehydration: tiredness, thirst,
dry mouth, dark and decreased amount of urine, or dizziness (particularly with standing).
Always inform your health care provider if you experience any unusual symptoms.
- Before starting Zolinza treatment, make sure you tell your doctor about any other
medications you are taking (including prescription, over-the-counter, vitamins,
herbal remedies, etc.).
- Do not receive any kind of immunization or vaccination without your doctor’s approval
while taking Zolinza.
- Inform your health care professional if you are pregnant or may be pregnant prior
to starting Zolinza. Pregnancy category D (zolinza may be hazardous to the fetus.
Women who are pregnant or become pregnant must be advised of the potential hazard
to the fetus.)
- For both men and women: Do not conceive a child (get pregnant) while taking Zolinza.
Discuss with your doctor when you may safely become pregnant or conceive a child
- Do not breast feed while taking Zolinza.
- Drink at least two to three quarts of fluid every 24 hours, unless you are instructed
- You may be at risk of infection so try to avoid crowds or people with colds, and
report fever or any other signs of infection immediately to your health care provider.
- Wash your hands often.
- Use an electric razor and a soft toothbrush to minimize bleeding.
- Avoid contact sports or activities that could cause injury.
- To reduce nausea, take anti-nausea medications as prescribed by your doctor, and
eat small, frequent meals.
- Avoid sun exposure. Wear SPF 15 (or higher) sunblock and protective clothing.
- In general, drinking alcoholic beverages should be kept to a minimum or avoided
completely. You should discuss this with your doctor.
- Get plenty of rest.
- Maintain good nutrition.
- If you experience symptoms or side effects, be sure to discuss them with your health
care team. They can prescribe medications and/or offer other suggestions that are
effective in managing such problems.
- For flu-like symptoms, keep warm with blankets and drink plenty of liquids. There
are medications that can help reduce the discomfort caused by chills.
- Acetaminophen or ibuprophen may help relieve discomfort from fever, headache and/or
generalized aches and pains. However, be sure to talk with your doctor before taking
Monitoring and Testing:
You will be checked regularly by your doctor while you are taking Zolinza, to monitor
side effects and check your response to therapy. Periodic blood work will be obtained
to monitor your complete blood count (CBC) as well as the function of other organs
(such as your kidneys and liver) will also be ordered by your doctor.
How Zolinza 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 or apoptosis).
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.
Chemotherapy is most effective at killing cells that are rapidly dividing.
Unfortunately, chemotherapy does not know the difference between the cancerous cells
and the normal cells. The "normal" cells will grow back and be healthy but in the
meantime, side effects occur. The "normal" cells most commonly affected by
chemotherapy are the blood cells, the cells in the mouth, stomach and bowel, and
the hair follicles; resulting in low blood counts, mouth sores, nausea, diarrhea,
and/or hair loss. Different drugs may affect different parts of the body.
Zolinza is a Histone Deacetylase (HDAC) Inhibitor. Histone Deacetylase
is an enzyme that is normally present in the cells. In some cancer cells,
there is an overexpression of HDACs. It is believed that inhibition of the
HDAC activity causes cell cycle arrest and cell death. The exact mechanism
of action has not been fully described.
