Androgen inhibitors are medications that block the effects of androgens, which are male hormones like testosterone. These drugs are often used to treat conditions such as prostate cancer, where androgens can promote the growth of cancer cells. By reducing androgen levels or blocking their action, these inhibitors can help slow down or stop the progression of the disease. In addition to cancer treatment, androgen inhibitors can also be used for other health issues, such as polycystic ovary syndrome (PCOS) and severe acne. They work by balancing hormone levels, which can lead to improved symptoms and overall health for those affected by these conditions.
