Viagra generic 2011?

What happened with generic Viagra in 2011?

In 2011, generic versions of Viagra (sildenafil) were widely available in the U.S. after Pfizer’s sildenafil patent protections and exclusivity periods for Viagra had largely run their course, allowing other manufacturers to launch approved generic products. [1]

Which “generic Viagra” products were on the market then?

Generic sildenafil is sold under many label names depending on the manufacturer, but they all use sildenafil as the active ingredient. In 2011, you would typically see multiple FDA-approved generic manufacturers offering 25 mg, 50 mg, and 100 mg tablets (the same strengths commonly associated with Viagra). [1]

Did Viagra’s patents still matter in 2011?

Yes, but by 2011 the major practical driver for whether generics could sell was whether manufacturers could legally market sildenafil based on patent and regulatory status. Patent/market exclusivity details vary by jurisdiction and specific patent estates, which is why DrugPatentWatch.com tracks these issues for different drugs and manufacturers. [1]
