A patent currently prevents any generic Spiriva from being manufactured in the United States. While companies may claim to sell it online, these drugs may be substandard and potentially dangerous. The earliest that generic Spiriva could become available is in 2014, when the first patent expires.
Generic Spiriva: An OverviewSpiriva® (tiotropium bromide) is a prescription medication used to treat chronic obstructive pulmonary disease (COPD). It is part of a class of asthma drugs known as anticholinergics or antimuscarinics.
Spiriva is manufactured jointly by Boehringer Ingelheim Pharmaceuticals and Pfizer, Inc. It is currently under the protection of a patent that prevents any generic Spiriva from being manufactured in the United States. Yet, if you search the Internet for "generic Spiriva," you may find a number of companies selling it. The fact is that these medicines may be fake, substandard, and potentially dangerous. Generic Spiriva may be available from another country, but there is really no way of knowing if you are getting genuine Spiriva or not. You should not buy any generic versions of Spiriva until there is an approved version available.
