Product Introduction:
Bortenat 2mg Injection is an anti-cancer medication that belongs to the proteasome inhibitor class. It is widely used in chemotherapy regimens for treating multiple myeloma and mantle cell lymphoma (MCL). It prevents cancer cells from breaking down proteins needed for survival, causing them to die.
Uses of Bortenat 2mg
Bortenat 2mg is used for treating:
-
Multiple Myeloma – A type of blood cancer affecting plasma cells.
-
Mantle Cell Lymphoma (MCL) – A rare, aggressive form of non-Hodgkin’s lymphoma.
-
Waldenström’s Macroglobulinemia (Off-label Use) – A type of slow-growing lymphoma.
-
Light Chain Amyloidosis (Off-label Use) – A disorder where abnormal proteins build up in organs.
-
Other Hematological Malignancies (Experimental Uses).
How Bortenat 2mg Works (Mechanism of Action):
-
Bortezomib inhibits the 26S proteasome, a complex responsible for degrading damaged proteins in cells.
-
Cancer cells rely on proteasomes to regulate cell cycle and survival.
-
By blocking proteasome activity, Bortenat disrupts normal protein degradation, causing cancer cells to accumulate toxic proteins and die.
-
This leads to tumor shrinkage and slows disease progression.
