Zoladex prostate cancer drug. Nurse holding a box containing a syringe pre-filled with a Zoladex pellet. The pellet is inserted into the patient's abdomen and releases a controlled amount of the active drug over a set period of time. Zoladex 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.
