Generic Crixivan

Although the first patent for Crixivan (indinavir sulfate) has expired, no generic versions are available. This could be due to a later-expiring patent that is providing protection against generic competition. The next patent for Crixivan is set to expire in March 2018.

Generic Crixivan: An Overview

Crixivan® (indinavir sulfate) is a prescription AIDS and HIV medication. It belongs to a class of medications known as protease inhibitors.
 
Crixivan is made by Merck & Co., Inc. It is currently under the protection of patents that prevent any generic Crixivan from being manufactured in the United States. Yet, if you search the Internet for "generic Crixivan," you may find a number of companies selling it. The fact is, these medicines may be fake, substandard, and potentially dangerous. There may be generic Crixivan available from another country, but there is really no way of knowing if you are getting genuine Crixivan or not. You should not buy any generic Crixivan until there is an approved generic available.
 

When Will Generic Crixivan Be Available?

The first patent for Crixivan expired in May 2012. Yet, no generic versions are available. This suggests that one or more of the later-expiring Crixivan patents is providing significant protection against generic competition. The next patent will expire in March 2018. This is the earliest possible date that a generic version of Crixivan could become available.
 
However, there are other circumstances that could come up to extend the exclusivity period of the medication beyond 2018. This could include such things as other patents for specific Crixivan uses or lawsuits. Once Crixivan goes off patent, there may be several companies that will manufacture a generic Crixivan drug.
