Zoladex LA 10.8mg Injection

1. Product Introduction

Zoladex LA 10.8mg Injection is a long-acting hormonal therapy used in the treatment of certain hormone-sensitive conditions in both men and women. It contains Goserelin acetate, a synthetic analog of the natural gonadotropin-releasing hormone (GnRH). This medicine is administered via subcutaneous injection (under the skin), typically in the abdominal region, and is designed to release the medication slowly over a period of 12 weeks.

Zoladex LA works by reducing the production of sex hormones—testosterone in men and estrogen in women. It does this by acting on the pituitary gland to suppress the signals that stimulate the production of these hormones. As a result, it effectively lowers hormone levels in the body, which is especially beneficial in conditions like prostate cancer, breast cancer, and endometriosis.

This medication is typically used as part of a larger treatment regimen and may be combined with other therapies such as chemotherapy, radiotherapy, or surgery. Zoladex LA is prescribed and administered under strict medical supervision.
