Product Introduction:
Zelgor 500 mg is a hormonal therapy medication used to treat advanced-stage prostate cancer that has spread beyond the prostate gland. It is especially effective for:
-
Metastatic castration-resistant prostate cancer (mCRPC)
-
Metastatic hormone-sensitive prostate cancer (mHSPC)
Since prostate cancer cells rely on androgens (male hormones) to grow, Zelgor blocks androgen production, helping to control the disease and improve survival rates. Prednisone is required along with Zelgor to prevent side effects like high blood pressure and fluid retention.
Uses of Zelgor 500 mg
Zelgor is primarily used in the treatment of advanced prostate cancer. The main uses include:
-
Metastatic Castration-Resistant Prostate Cancer (mCRPC) – Used when prostate cancer has spread and does not respond to standard hormone therapy.
-
Metastatic Hormone-Sensitive Prostate Cancer (mHSPC) – Combined with prednisone to enhance survival rates.
-
Prostate Cancer Progression Control – Slows down cancer growth by reducing androgen levels.
-
Delaying the Need for Chemotherapy – Helps patients avoid or delay chemotherapy.
-
Post-Surgical Treatment for Prostate Cancer – Sometimes prescribed after surgery to prevent cancer recurrence.
How Zelgor 500 mg Works (Mechanism of Action):
Zelgor (Abiraterone Acetate) is a CYP17 enzyme inhibitor that blocks androgen (male hormone) production, which prostate cancer cells need to grow.
-
Inhibits the CYP17 enzyme, which is essential for testosterone synthesis.
-
Prevents the conversion of pregnenolone and progesterone into testosterone in the adrenal glands, testes, and tumor cells.
-
Reduces androgen levels, slowing cancer progression and reducing tumor size.
Because Abiraterone disrupts hormone levels, prednisone is always prescribed along with it to balance hormones and minimize complications.
Dosage of Zelgor 500 mg
Recommended Dosage:
-
Standard Dose: 1000 mg per day (Two 500 mg tablets once daily)
-
Taken with prednisone: Usually 5 mg twice daily
-
Doctor may adjust the dose based on patient response and side effects.
For patients with liver issues:
-
Dose adjustments may be required based on liver function tests.
Method of Administration (How to Take It)
-
Take Zelgor on an empty stomach, at least 1 hour before or 2 hours after a meal.
-
Swallow the tablets whole with a full glass of water.
-
Do not chew, crush, or break the tablets before swallowing.
-
Take the medication at the same time every day for best results.
-
Prednisone is required alongside Zelgor to balance hormone levels and reduce side effects.
