My husband has been receiving Zoladex injections for advanced prostate cancer (every 3 mos) with good response since Oct 08. His local clinic here in the UK which administers the Zoladex has informed us that his next shot will be changed to a drug called Decapeptyl SR. Can you tell us why this change might be in place? Is it a less costly variant of the same drug? If not, why change?
In the USA, Decapeptyl is known as Trelstar. It is not cheaper and personally I think it is a better drug than Zoladex. I base this opinion on the fact that the needle used is smaller and causes less pain.
