Even though all of the patents and exclusivity rights have expired for Emcyt (estramustine), a generic version of this drug is not yet available. It is unknown why a manufacturer has not chosen to make a generic Emcyt product, although it may be because the demand for the drug is too small for such a product to be profitable.
Can I Buy Generic Emcyt?Emcyt® (estramustine phosphate) is a prescription medication approved to treat certain men with prostate cancer. It belongs to a group of medicines known as antimicrotubule agents.
Emcyt is made by Pharmacia & Upjohn Company, a division of Pfizer, Inc. Although it is no longer protected by patents, there are no generic versions of Emcyt available in the United States.
When Will a Generic Version Be Available?Emcyt is a relatively old medication. It was approved by the U.S. Food and Drug Administration (FDA) prior to 1982, and is no longer protected from generic competition by patents or exclusivity rights. Normally, when the patents for a medication expire, manufacturers will make a generic version. However, no manufacturers have chosen to make a generic version of Emcyt.
At this time, it is not entirely clear why a manufacturer has not chosen to make a generic Emcyt medication. It could be that the demand for this medication is too small for a manufacturer to profit from making a generic Emcyt.
However, because it is unknown why a manufacturer has not chosen to make a generic form of Emcyt, it is impossible to predict when, or even if, a generic version will become available.
Is Estramustine a Generic Emcyt?No, estramustine is the active ingredient in Emcyt, not a generic version of it. What can be confusing is that the active ingredient of a drug is often referred to as the "generic name."
The generic name is different from a generic version of a medicine. In order for there to be a generic version, the original medicine must have gone off-patent and another company besides the original manufacturer must make the product.
