What is Vinorelbine?
Commonly used as a chemotherapy treatment, vinorelbine is meant for aggressive cancers like metastatic breast cancer, non-small cell lung cancer, and mesothelioma. The medication comes from the alkaloids extracted from the rosy periwinkle plant, scientifically known as Catharanthus roseus.
French pharmacist Pierre Potier and his team invented vinorelbine in the 1980s. France approved the medication in 1989 for lung cancer treatment and for breast cancer treatment in 1991.
The United States first approved vinorelbine for non-small cell lung cancer treatment in 1994. The medication remains on the World Health Organization’s List of Essential Medicines.
Cancer patients often use Navelbine, a brand name of vinorelbine.
How Vinorelbine Works
Cancerous tumors spread by cell division (mitosis). The function of vinorelbine is to stop cell division by disrupting the body’s microtubules, which are structures that contribute to cell production.
Chemotherapy cannot tell the difference between cancerous cells and healthy cells, leading to its side effects. While the medication stops the spread of malignant blood cells, mitosis of healthy cells slows.
Doctors administer the chemotherapy by injection into a vein or by mouth. Patients typically receive the medication in six-week cycles with a combination of another chemotherapy drug, depending on the patient’s health.
Doctors may use vinorelbine as a form of palliative therapy to improve the quality of life for mesothelioma patients who may not tolerate other cancer treatments.
Doctors may use vinorelbine as second-line therapy in patients with recurrent mesothelioma who have already received standard chemotherapy as a treatment option.
Vinorelbine Side Effects
Since the treatment disrupts normal cell function, some patients may experience side effects. However, most patients do not experience all of the side effects, and most doctors can predict how long they will last.
Side effects do not influence the effectiveness of the medication, and there are options to minimize or prevent them. About 30 percent of patients receiving vinorelbine experience side effects. Common side effects include:
- Low blood counts
- Muscle weakness
- Nausea or vomiting
Less common side effects are:
- Hair loss
- Low platelet counts (cell fragments that help clot the blood)
- Numbness in fingers and toes (peripheral neuropathy)
- Pain among the administration site
Vinorelbine is typically low in toxicity compared to other chemotherapy treatments. However, the medication may affect specific organs in the body.
Mild to moderate nerve damage may occur in patients who use vinorelbine as treatment, resulting in reduced or abnormal touch sensation.
About 12 percent of patients who take vinorelbine experience mild, sudden hair loss. Patients may also experience injection site reactions, including pain or vein discoloration.
Some patients may experience shortness of breath when receiving vinorelbine.
