Abiraterone Acetate

What is Abiraterone Acetate?

Abiraterone acetate is a prescription medication used to treat certain forms of prostate cancer. It belongs to a class of medicines known as androgen biosynthesis inhibitors, which reduce the production of male hormones that can promote the growth of prostate cancer cells.

Prostate cancer cells often depend on androgens (male hormones such as testosterone) to grow and multiply. Abiraterone acetate works by lowering the levels of these hormones in the body.

Common medical uses include:

Treatment of metastatic castration-resistant prostate cancer (mCRPC)

Treatment of metastatic high-risk castration-sensitive prostate cancer (mCSPC)

This medication is often prescribed together with corticosteroids such as prednisone to help manage hormone-related side effects.

Abiraterone acetate helps slow cancer progression and control symptoms, but it does not cure prostate cancer.

Available formulations and strengths

Abiraterone acetate is typically available as:

Oral tablets

Tablet strengths may vary depending on manufacturer and country, commonly including:

250 mg tablets

500 mg tablets

Formulations may differ based on regulatory approvals and pharmaceutical manufacturers.

What is the Recommended Dosage of Abiraterone Acetate?

The appropriate dosage must be determined by a licensed healthcare professional, usually an oncologist or cancer specialist.

Dosage may vary depending on:

The type and stage of prostate cancer

Overall health status

Liver function

Other cancer treatments being used

Response to therapy

Dosage forms

Abiraterone acetate is administered as:

Oral tablets taken by mouth

Patients are usually instructed to take the medication on an empty stomach, as food may significantly increase absorption.

Abiraterone acetate is often prescribed together with a corticosteroid to reduce hormone-related side effects.

Patients should strictly follow the dosing instructions provided by their oncologist and should not change the dose without medical guidance.

How Abiraterone Acetate Works

Abiraterone acetate works by blocking an enzyme called CYP17 (17α-hydroxylase/C17,20-lyase), which is involved in the production of androgens.

Androgens are produced in several parts of the body, including:

The testes

The adrenal glands

Prostate tumor tissue

By inhibiting CYP17, abiraterone acetate reduces the production of these hormones throughout the body.

Lower androgen levels help:

Slow the growth of prostate cancer cells

Reduce tumor progression

Improve disease control in certain patients

Although this therapy can help manage prostate cancer, it does not eliminate the disease completely.
