Vinblastine Sulfate

(vin-BLAST-een)

Trade names: Alkaban-AQ®, Velban®

Other names: Vinblastine Sulfate, Vincaleukoblastine, VLB

Vinbastine is the generic name for the trade name drug Alkaban-AQ® or Velban®. In some cases, health care professionals may use the trade names Alkaban-AQ and Velban® or other names; such as VLB, Vinblastine Sulfate, or Vincaleukoblastine when referring to the generic drug name vinblastine.

Drug type: Vinblastine is an anti-cancer ("antineoplastic" or "cytotoxic") chemotherapy drug. This medication is classified as a "plant alkaloid." (For more detail, see "How vinblastine works" section below).

What Vinblastine Sulfate Is Used For:

  • This drug is given to treat Hodgkin lymphoma, non-Hodgkin's lymphoma, testicular, breast, lung (Non-small cell lung cancer), head and neck, and bladder cancers, melanoma, soft tissue sarcoma, Kaposi's sarcoma, mycosis fungoides (t-cell lymphoma), and choriocarcinoma. It can be used to treat fibromatosis and germ cell tumour.
  • It is also used in the treatment of certain blood disorders such as histiocytosis

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 Vinblastine Sulfate Is Given:

  • Vinblastine is given through a vein by intravenous injection (IV push) or infusion (IV). There is no pill form.
  • Vinblastine is a vesicant. A vesicant is a chemical that causes extensive tissue damage and blistering if it escapes from the vein. The nurse or doctor who gives this drug must be carefully trained. If you notice pain, redness or swelling at the IV site while you are receiving vinblastine, alert your health care professional immediately.

The amount of vinblastine you will receive depends on many factors, including your height and weight, your general health or other health problems, and the type of cancer or condition being treated. Your doctor will determine your dose and schedule.

Side Effects:

Important things to remember about the side effects of vinblastine include:

  • Most people do not experience all of the vinblastine side effects listed.
  • Vinblastine's side effects are often predictable in terms of their onset and duration.
  • Vinblastine's side effects should improve after treatment is complete.
  • Vinblastine's side effects are usually quite manageable. There are many options to help minimize or prevent the side effects of vinblastine.

The following side effects are common (occurring in greater than 30%) for patients taking vinblastine:

The following are less common side effects (occurring in 10-29%) for patients receiving vinblastine:

Not all side effects are listed above, some that are rare (occurring in less than 10% of patients) are not listed here. However, 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:

  • Fever of 100.4° F (38° C) or higher, chills (possible signs of infection)

The following symptoms require medical attention, but are not emergency situations. Contact your health care provider within 24 hours of noticing any of the following:

  • Severe constipation, unrelieved by laxative use
  • Nausea (interferes with ability to eat and unrelieved with prescribed medications)
  • 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) Mouth sores (painful redness, swelling or ulcers)

Always inform your health care provider if you experience any unusual symptoms.

Precautions:

  • Before starting vinblastine 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 vinblastine.
  • Inform your health care professional if you are pregnant or may be pregnant prior to starting this treatment. Pregnancy category D (vinblastine 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 vinblastine. Barrier methods of contraception, such as condoms, are recommended. Discuss with your doctor when you may safely become pregnant or conceive a child after therapy.
  • Do not breast feed while taking this medication.

Self-Care Tips:

  • Apply warm compress if you have any pain, redness or swelling at the IV site, and notify your doctor.
  • Keep your bowels moving. Your health care provider may prescribe a stool softener to help prevent constipation that may be caused by this medicine.
  • If you experience diarrhea of greater than 4-6 stools per day, contact your healthcare provider and increase your fluid intake.
  • Drink at least 2 to 3 quarts of fluid every 24 hours, unless you were stold to restrict your fluid intake, and maintain good nutrition. This will decrease your chances of being constipated, and prevent dehydration.
  • 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 healthcare provider.
  • Wash your hands often.
  • Use an electric razor and soft toothbrush to minimize bleeding.
  • Avoid contact sports or activities that could cause injury.
  • Avoid sun exposure. Wear SPF 30 (or higher) sun block and protective clothing.
  • To reduce nausea, take anti-nausea medications as prescribed by your doctor, and eat small, frequent meals.
  • Follow regimen of anti-diarrhea medication as prescribed by your health care professional.
  • Eat foods that may help reduce diarrhea (see managing side effects - diarrhea)
  • To help treat/prevent mouth sores, use a soft toothbrush, and rinse at least three times a day with 1/2 to 1 teaspoon of baking soda and/or salt in 8 ounces of water.
  • In general, drinking alcoholic beverages should be minimized or avoided. You should discuss this with your doctor.
  • Get plenty of rest
  • Maintain good nutrition
  • Remain active as your are able. Gentle exercise is encouraged such as daily walks
  • Use caution when driving or engaging in tasks that require alertness until response to the drug is known.
  • 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.

Monitoring and Testing:

You will be checked regularly by your doctor while you are taking vinblastine, 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 Vinblastine Sulfate 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 part of the body.

Vinblastine belongs to a class of chemotherapy drugs called alkaloids. Plant alkaloids are made from plants. The vinca alkaloids are made from the periwinkle plant (catharanthus rosea). The plant alkaloids are cell-cycle specific. This means they attack the cells during various phases of division.

  • Vinca alkaloids: Vincristine, Vinblastine and Vinorelbine

Antimicrotubule agents (such as vinblastine), inhibit the microtubule structures within the cell. Microtubules are part of the cell's apparatus for dividing and replicating itself. Inhibition of these structures ultimately results in cell death.
