March 15, 2016 | The US Food and Drug Administration (FDA) has awarded Israel’s Teva Pharmaceutical Industries Ltd. approval for the first-ever generic version of Viagra. Teva’s generic version, which will be available to the public in the US from December 11 2017, will be available in 25, 50 and 100 milligram tablets and Teva will have 180 days exclusive generic marketing. Viagra is a branded drug produced and marketed by Pfizer. After protracted patent litigation, in which Pfizer claimed its patent was good until 2020, the two companies came to a compromise agreement in 2013, allowing Teva to market a generic version of the drug from December 2017.
