Product Introduction:
Myezom 2mg Injection is a chemotherapy drug classified as a proteasome inhibitor. It is commonly prescribed for multiple myeloma and mantle cell lymphoma (MCL). The drug blocks a cellular system responsible for protein degradation, leading to the accumulation of toxic proteins inside cancer cells, ultimately causing their death.
Myezom 2mg is prescribed for the treatment of:
-
Multiple Myeloma – A type of blood cancer that affects plasma cells in the bone marrow.
-
Mantle Cell Lymphoma (MCL) – A rare and aggressive type of non-Hodgkin’s lymphoma.
-
Waldenström’s Macroglobulinemia (Off-label Use) – A slow-growing type of lymphoma.
-
Light Chain Amyloidosis (Off-label Use) – A condition where abnormal proteins accumulate in organs.
-
Other Hematological Malignancies (Experimental Uses).
How Myezom 2mg Works (Mechanism of Action):
-
Bortezomib inhibits the 26S proteasome, an enzyme that cancer cells use to degrade unwanted proteins.
-
By blocking proteasome function, cancer cells accumulate toxic proteins, leading to cellular stress and apoptosis (cell death).
-
This process halts tumor growth and slows down cancer progression.
