Eurolide 4mg/4ml injection (Leuprolide/Leuprorelin) is a hormonal therapy used to manage prostate cancer, endometriosis, uterine fibroids, and central precocious puberty by inhibiting testosterone or estrogen production. It works as a GnRH agonist to slow cancer cell growth, reduce uterine tissue growth, shrink fibroids, and delay early puberty, often improving patient quality of life.
