Product Introduction:
Samtica 500 mg is a hormonal therapy drug primarily used to treat advanced-stage prostate cancer that has spread beyond the prostate gland.
It is prescribed in:
-
Metastatic Castration-Resistant Prostate Cancer (mCRPC) – When the disease continues to progress despite hormonal therapy or surgical castration.
-
Metastatic Hormone-Sensitive Prostate Cancer (mHSPC) – Used early in advanced cases to improve survival and slow disease progression.
Since prostate cancer cells need androgens (male hormones) like testosterone to grow, Samtica 500 mg works by reducing androgen production, helping slow down cancer spread. Prednisone is always prescribed alongside Samtica to prevent potential hormone-related side effects.
Uses of Samtica 500 mg
Samtica is primarily used for prostate cancer treatment in the following conditions:
-
Metastatic Castration-Resistant Prostate Cancer (mCRPC) – When cancer continues to grow despite standard hormonal therapy.
-
Metastatic Hormone-Sensitive Prostate Cancer (mHSPC) – Helps improve overall survival in newly diagnosed advanced cases.
-
Delaying Chemotherapy – Helps patients avoid or postpone chemotherapy.
-
Post-Surgical Treatment – Used to lower the risk of cancer recurrence after surgery.
-
Prostate Cancer Symptom Relief – Helps reduce pain and discomfort caused by tumor growth.
How Samtica 500 mg Works (Mechanism of Action):
Samtica (Abiraterone Acetate) is a CYP17 enzyme inhibitor that blocks testosterone production, which is crucial for prostate cancer cell survival.
-
Inhibits the CYP17 enzyme, a key enzyme in testosterone synthesis.
-
Stops the production of androgens (testosterone and related hormones) from the adrenal glands, testes, and tumor cells.
-
Lowers overall androgen levels, reducing tumor growth and slowing disease progression.
Because testosterone reduction can disrupt hormone balance, prednisone is always prescribed alongside Samtica to prevent complications such as high blood pressure and fluid retention.
