There are no generic Azopt (brinzolamide) products available at this time. The first patent has expired, so the drug could be under the protection of a patent that hasn't expired yet. It's important to note that brinzolamide is the "generic name" for this product; it's not a "generic version."
Azopt® (brinzolamide) is a prescription eye drop approved for the treatment of glaucoma and high eye pressure. Azopt belongs to a group of medications known as carbonic anhydrase inhibitors and works to lower eye pressure by decreasing the fluid production in the eye.
Brand-name Azopt is manufactured by Alcon Laboratories, Inc. There are no generic versions of Azopt approved for use or sale in the United States.
However, if you search the Internet for "generic Azopt," you may find a number of companies selling it. The fact is that these medicines may be fake, substandard, and potentially dangerous.
There may be generic Azopt available from another country, but there is really no way of knowing if you are getting genuine Azopt or not. You should not buy anything claiming to be generic Azopt until there is an approved version available.
The first patent for Azopt expired in March 2011. However, because no generic versions are available, it appears that later expiring patents are probably protecting the drug from generic competition. The next Azopt patent was set to expire in October 2012, but was given an extension until April 2013. This is the earliest predictable date that a generic version of the medication could become available.
However, there are other circumstances that could come up to extend or shorten the exclusivity period of Azopt, such as lawsuits or other patents for specific Azopt uses.
Once Azopt goes off-patent, there may be several companies that manufacture a generic Azopt drug.
