Bortenat 2mg (Bortezomib) Injection is a significant therapeutic advancement in the treatment of certain types of cancers, particularly multiple myeloma and mantle cell lymphoma. Bortezomib belongs to a class of medications known as proteasome inhibitors, which play a crucial role in the regulation of cellular processes by breaking down proteins that control cell division and growth. By inhibiting the proteasome, Bortezomib disrupts these processes in cancer cells, leading to their death or inhibition of growth.
