Introduction to Xtandi (Enzalutamide) 40mg
Xtandi (Enzalutamide) 40mg is a prescription medicine used in the treatment of certain types of prostate cancer, especially advanced or metastatic prostate cancer. This medicine belongs to a specialized group of anticancer drugs that work by blocking the action of male hormones that help prostate cancer cells grow.
Xtandi (Enzalutamide) 40mg is classified under Prescription Medicines, Oncology Medicines, Anticancer Drugs, and Oral Cancer Therapies. It contains Enzalutamide, which works by inhibiting androgen receptor signaling and helping slow the growth and spread of prostate cancer cells.
In some markets, Mestiza 40mg is available as a local brand containing the same active ingredient Enzalutamide, offering a similar therapeutic effect when prescribed by a qualified healthcare professional.
What Is Xtandi (Enzalutamide) 40mg?
Xtandi is the original brand name for Enzalutamide, an oral medication widely used for the treatment of prostate cancer.
Enzalutamide belongs to a class of medicines known as Androgen Receptor Inhibitors. These medicines help block the effects of androgens such as testosterone, which can stimulate the growth of prostate cancer cells.
Generic or local brands such as Mestiza 40mg contain the same active compound and may be used depending on physician recommendation and regional availability.
Drug Class and Mechanism of Action
Enzalutamide is classified as an androgen receptor inhibitor with strong antineoplastic properties.
How Enzalutamide Works
It works in several ways:
- Blocks androgen receptors on prostate cancer cells
- Prevents androgen-driven cancer cell growth signals
- Inhibits cancer cell survival and proliferation
- Helps slow disease progression in advanced prostate cancer
Through these mechanisms, Enzalutamide helps slow or stop the progression of certain prostate cancers.
How Xtandi Works in the Body
Prostate cancer cells often depend on androgen hormones for growth. Xtandi helps block these hormonal signals and interferes with the cancer’s ability to survive and spread.
Key Actions of Enzalutamide
- Blocking androgen receptor activity
- Preventing hormone-driven tumor growth
- Slowing progression of metastatic prostate cancer
- Supporting long-term disease control in selected patients
Some local brands such as Mestiza deliver the same active compound, allowing similar hormone-targeted cancer treatment when prescribed appropriately.
