Zoladex implant in prostate cancer. Close-up of a doctor implanting a capsule of goserelin acetate, marketed under the name Zoladex, under the skin of a patient with prostate cancer. The capsule releases a controlled amount of the active drug over a set period of time. It is an LHRH (luteinising hormone-releasing hormone) blocker that is used to treat prostate cancer. It acts on the pituitary gland in the brain to prevent it producing luteinising hormone, the hormone that tells the testes to produce testosterone. In prostate tumours that are sensitive to testosterone, this causes the tumour to shrink. It does not provide a cure, but does increase life expectancy.
