Product Introduction:
Prostiga 250 mg is a hormonal therapy drug used in metastatic prostate cancer. Prostate cancer cells depend on testosterone to grow and spread, and this medication helps reduce testosterone production, slowing the progression of the disease.
Prednisone is prescribed alongside Prostiga to prevent side effects such as high blood pressure and fluid retention.
Uses of Prostiga 250 mg
Prostiga is primarily used for treating advanced-stage prostate cancer, including:
-
Metastatic Castration-Resistant Prostate Cancer (mCRPC) – For patients whose cancer continues to grow despite previous hormonal therapy or surgical castration.
-
Metastatic Hormone-Sensitive Prostate Cancer (mHSPC) – For newly diagnosed advanced prostate cancer to slow progression.
-
Delaying Chemotherapy – Helps in postponing chemotherapy in advanced prostate cancer patients.
-
Post-Surgical Therapy – Reduces the risk of cancer recurrence after surgery.
-
Symptom Management in Prostate Cancer – Relieves pain, urinary difficulties, and other cancer-related symptoms.
How Prostiga 250 mg Works (Mechanism of Action):
Prostiga (Abiraterone Acetate) is a CYP17 enzyme inhibitor that blocks testosterone production, which fuels prostate cancer growth.
-
Inhibits the CYP17 enzyme, a key enzyme involved in testosterone synthesis.
-
Reduces androgen production in the testes, adrenal glands, and prostate tumor cells.
-
Slows down tumor growth by depriving cancer cells of testosterone.
-
Used with prednisone to counteract side effects such as high blood pressure and fluid retention.
