HalavenTM (There may be other names for this medication)
How is it Administered?
This medication is given by injection into a vein (intravenous or IV), usually in your arm, wrist, hand, or chest. Eribulin is usually given on days 1 and 8 of a 21-day treatment cycle.
What is it Used For?
Eribulin is used to treat breast cancer that has spread to other parts of the body (metastasized) and that has already been treated with certain other chemotherapies.
How Does it Work?
Cancer is a group of diseases in which abnormal cells reproduce without control. Your chemo schedule is based upon your cancer type, how fast the cancer cells multiply, and the time of the cells’ reproductive cycle when the medication is the most likely to be effective. This is why chemotherapy is typically given in cycles.
Eribulin is in a class of drugs known as microtubule dynamics inhibitors. It works by interrupting the normal cell cycle of the cancer cells and causing the cancer cells to die.
The faster cells reproduce, the more likely it is that chemotherapy will damage and/or kill them. Since there are some types of cells in your body that naturally reproduce rapidly, these types of cells are likely to be damaged/destroyed by chemo. These normal cells will eventually grow back and be healthy. During treatment, however, you may experience side effects involving the cells that line the digestive tract (mouth, stomach, and intestines), the hair follicles, and bone marrow.
