Cancer treatments often come with significant financial burdens, making it crucial for patients and caregivers to understand the costs associated with specific medications. This article delves into the prices of two critical cancer drugs: Xtandi and Cabozantinib. We will explore what these drugs are, their importance in cancer treatment, and how their pricing impacts patients worldwide.
1. Introduction to Xtandi and Cabozantinib
1.1. What is Xtandi?
Xtandi (Enzalutamide) is an oral medication primarily used in the treatment of prostate cancer, particularly in cases where the disease has metastasized or become resistant to traditional hormone therapies. Xtandi works by inhibiting the action of androgens (male hormones) that can promote the growth of cancer cells. It is often prescribed for patients with metastatic castration-resistant prostate cancer (mCRPC) and non-metastatic castration-resistant prostate cancer (nmCRPC).
1.2. What is Cabozantinib?
Cabozantinib, sold under the brand names Cabometyx and Cometriq, is another oral medication used to treat several types of cancer, including advanced renal cell carcinoma (kidney cancer), hepatocellular carcinoma (liver cancer), and medullary thyroid cancer. Cabozantinib works as a tyrosine kinase inhibitor, blocking enzymes that promote cancer cell growth and blood vessel formation within tumors.
2. The Importance of Xtandi and Cabozantinib in Cancer Treatment
