Neratinib

Neratinib is a prescription medication used to treat certain types of breast cancer. It belongs to a group of drugs called tyrosine kinase inhibitors. It works by blocking the activity of certain proteins that are involved in the growth and spread of cancer cells. Neratinib is used to treat breast cancer that has spread to other parts of the body and is no longer responding to other treatments. It is also used to help prevent the cancer from returning after surgery.

Neratinib is a prescription medication used to treat certain types of breast cancer [1]. Here's a breakdown of its key information:

• Type of Cancer: Neratinib is specifically indicated for HER2-positive breast cancer, a subtype characterized by the overexpression of a protein called HER2 on the surface of cancer cells [1, 2].
• Function: Neratinib belongs to a class of drugs called tyrosine kinase inhibitors (TKIs). TKIs work by blocking specific proteins (tyrosine kinases) that are involved in the growth and spread of cancer cells [1]. In HER2-positive breast cancer, neratinib targets HER2 protein signaling, thereby helping to slow or stop the growth of cancer cells.
• Use Cases: Neratinib is typically used in combination with other medications for the treatment of HER2-positive breast cancer in two main scenarios:
  • Early stage: After surgery and primary therapy (like chemotherapy or trastuzumab) to treat HER2-positive breast cancer, neratinib may be used to reduce the risk of the cancer recurring (coming back) [1].
  • Advanced or metastatic stage: For HER2-positive breast cancer that has spread to other parts of the body (metastasized), neratinib can be used in combination with other medications to slow or stop cancer progression [1].
• Dosage form: Neratinib comes as tablets taken orally [1].

Important notes:

• Neratinib can cause side effects, including diarrhea, nausea, vomiting, abdominal pain, skin rash, fatigue, and mouth sores [1].
• It can also interact with other medications, so it's vital to inform your doctor about all medications, supplements, or herbal remedies you're taking before starting neratinib [1].
• Neratinib may not be suitable for everyone, particularly those with certain medical conditions or pregnant or breastfeeding women [1].
