Casodex (Bicalutamide) is an antiandrogen prescribed in the treatment of prostate cancer.







150 mg, 50 mg



I. Introduction

The history and discovery of Casodex, also known as bicalutamide, dates back to the 20th century when it was developed as a significant breakthrough in hormone therapies. Initially designed to tackle prostate cancer, its identification marked a milestone in oncology treatment and paved the way for targeted therapies. Casodex is classified as a steroidal antiandrogen (NSAA) and plays a crucial role in modern medicine. By blocking the binding of dihydrotestosterone (DHT) to androgen receptors, it helps reduce the growth-promoting effects of these hormones on prostate cancer cells. This compound represents one of the forefront treatments for prostate cancer today, offering hope and therapeutic relief to patients.

II. Uses

Casodex (bicalutamide) is a medication mainly used to treat prostate carcinoma. It functions as a hormone therapy that effectively combats the androgenic triggers responsible for the growth and spread of malignant prostate cells 12The duration of treatment varies depending on the progression of the disease and how patients respond, typically ranging from several months to years 2Casodex is commonly prescribed for advanced non-metastatic prostate cancer and can also be used alongside other therapies for metastatic conditions 1.

III. How it Works

Casodex works by blocking androgen receptors, which is crucial for its effectiveness. This blocking action prevents the activation of genes that encourage the growth of tumors in prostate cells. Androgens and testosterone have a significant role in male physiology and the development of prostate cancer. Unfortunately, they unintentionally support tumors' expansion by fueling prostate cell growth. Casodex counteracts this by hindering its activity, depriving the cancer of its growth stimulus. Although Casodex specifically targets androgen receptors, it doesn't suppress testosterone production. Instead, it limits its distribution and function to ensure that this hormone doesn't promote the growth of cells.

IV. Off-label Use

Studies and research have explored the use of Casodex beyond its approved purpose for treating prostate cancer. Although in the early stages, some studies indicate that it might be helpful in conditions like hirsutism and certain types of breast cancer. However, using Casodex for these purposes requires careful consideration due to safety concerns. It is essential to balance the benefits, like symptom relief, with the risks of unexpected side effects. This calls for clinical investigation and evaluation 12.
