Product Introduction
Abirapro 250mg is a potent androgen biosynthesis inhibitor used to treat metastatic prostate cancer. It helps slow the progression of cancer by blocking androgen (male hormone) production, which fuels prostate cancer growth. Abirapro is a trusted treatment option for metastatic castration-resistant prostate cancer (mCRPC) and metastatic high-risk castration-sensitive prostate cancer (mCSPC), often prescribed in combination with prednisone to improve effectiveness and minimize side effects.
Uses of Abirapro 250mg
Abirapro 250mg is prescribed for:
-
Metastatic Castration-Resistant Prostate Cancer (mCRPC) – Prostate cancer that continues to spread despite hormone therapy.
-
Metastatic High-Risk Castration-Sensitive Prostate Cancer (mCSPC) – Newly diagnosed prostate cancer that has spread beyond the prostate gland.
-
Combination Therapy with Prednisone – Enhances the drug’s effectiveness and reduces side effects.
-
Reducing PSA Levels – Helps lower prostate-specific antigen (PSA), a marker of cancer progression.
-
Slowing Disease Progression – Inhibits tumor growth and delays the need for chemotherapy.
-
Improving Quality of Life – Helps manage symptoms like bone pain and urinary problems in prostate cancer patients.
How Abirapro 250mg Works
Abirapro 250mg contains Abiraterone Acetate, which is converted into Abiraterone in the body. It works by:
- Inhibiting the CYP17 Enzyme – This enzyme plays a key role in the production of androgens.
- Reducing Testosterone Production – Prostate cancer cells require testosterone to grow. Abirapro blocks its production from the testes, adrenal glands, and tumor cells.
Suppressing Tumor Growth – By cutting off the hormone supply, it slows the cancer’s spread and improves survival.
Dosage
- Recommended Dose: 1000mg (4 tablets of 250mg) once daily

- Duration: Continued as long as clinical benefit is observed and side effects are manageable
