Product Introduction:
Cabaxan 60mg Injection is an anti-cancer chemotherapy medication used in the treatment of metastatic castration-resistant prostate cancer (mCRPC) in patients who have previously received docetaxel-based therapy. It belongs to the taxane class of chemotherapy drugs, which prevent cancer cells from dividing and multiplying.
Uses of Cabaxan 60mg
Cabaxan 60mg is used for the treatment of:
-
Metastatic Castration-Resistant Prostate Cancer (mCRPC) – Prostate cancer that no longer responds to hormonal therapy.
-
Prostate Cancer After Docetaxel Therapy – For patients whose cancer has progressed despite previous chemotherapy with docetaxel.
-
Other Experimental Uses in Solid Tumors (Under Investigation).
How Cabaxan 60mg Works (Mechanism of Action):
-
Cabazitaxel binds to tubulin, a protein needed for cell division.
-
It prevents microtubule disassembly, disrupting the normal cell cycle.
-
This causes cancer cells to stop dividing, leading to apoptosis (programmed cell death).
-
Unlike other taxanes, Cabazitaxel works in resistant tumors that no longer respond to docetaxel.
