PROSTAP SR, also known as Leuprorelin or Leuprolide acetate, is a type of medication commonly used in the management of hormone-responsive cancers such as prostate cancer in men and breast cancer in women, as well as conditions like endometriosis and uterine fibroids. It belongs to a class of drugs known as gonadotropin-releasing hormone (GnRH) agonists, which work by decreasing the amount of testosterone in men and estrogen in women. This reduction in hormone levels helps to slow the growth of hormone-sensitive tumors and can alleviate symptoms of conditions like endometriosis. PROSTAP SR is administered through an injection, typically on a monthly basis, making it a convenient option for patients requiring long-term hormone suppression therapy. Its use, however, must be closely monitored by healthcare professionals due to potential side effects and the need for dosage adjustments based on the patient's response to treatment.
