Vinblastine is a chemotherapy drug that is used to treat various types of cancer. It is derived from the periwinkle plant and works by interfering with cancer cell growth and division. There are several synonyms for vinblastine, including Velban, Vincaleukoblastine, and Vinblastin Sulfate. These different names for the drug all refer to the same chemical compound and are used interchangeably. While vinblastine can be an effective treatment for certain cancers, it can also have side effects such as nausea, vomiting, and hair loss. It is important to discuss potential side effects and treatment options with a healthcare provider to determine the best course of action.
