Viagra generic entryThe story of Viagra’s patents and generic entry of sildenafil citrate is a valuable one because it covers many of the nuances of drug patenting and generic entry in the United States.
This article will describe the multiple patents, patent term extension, pediatric extension, litigation, out-of-court-settlement, and authorized generic fighter brand elements which led to Viagra’s long patent life and limited early entry of generics, and Pfizer’s post generic-entry strategy to limit the impact of competitors.
was approved in 1998, and the original patent covering Viagra was, which received a 283-day patent term extension giving it an expiration date of March 29th, 2012. This 14-year patent life is longer than many other drugs, but Pfizer was able extend the patent-protected life even further.
The ‘534 patent was filed in 1990, and in 1994 (four years prior to Viagra’s launch) Pfizer filed a second patent:. Because the ‘012 patent was filed prior to June 8th 1995 its term is17 years from the grant date, rather than20 years from the filing date, which is how expiration is determined for patents filed after Jun 8th 1995. The ‘012 patent was granted on October 22nd, 2002, so the original expiration date was set to October 22nd, 2019 — more than twenty years after the drug’s launch. The patent’s expiration was extended to April 22nd 2020 because Pfizer responded to an FDA request to perform pediatric clinical trials, granting six months of “” protection.
Pfizer successfully defended Viagra’s patents in many over the years, but one lawsuit stands out. Despite prevailing in awhich affirmed the validity of patent 6,469,012, in 2013 Pfizer announced an, granting Teva a license to manufacture and sell genericstarting in December 2017, more than two years before Viagra’s patent expiration. Importantly, this was not a ‘‘ patent settlement, as Teva was required to pay Pfizer a licensing fee to produce the generic.
Generic drugs sell at a discount to the branded version, which hurts branded revenues, but there are things which brands can do to limit the impact. A popular tactic it to launch an. In this strategy the branded firm licenses a third party to market the branded drug under another name, compelling the generic entrant (in this case Teva) to compete in the generic market. The authorized generic for Viagra was and it was.
Viagra’s 2016 US sales were approximately 1.2 billion, and in 2017 they dropped to less than $800 million. With increased competition from Teva and from Revatio, revenues are expected to keep dropping, and widespread generic competition from the many companies with will further-decrease Viagra sales. It appears that Pfizer is responding to increased competition by increasing Viagra’s price — the has been a general increase over time.
The story of Viagra and the generic entry of sildenafil citrate illustrates the value of data and the need to continuously re-evaluate factors affecting generic entry. Reliance on the first patent would have vastly under-estimated the date of generic entry, and looking solely at the expiration date of the second patent would have missed the December 2017 generic entry.

This month, the Food and Drug Administration approves Pfizer’s Viagra, the first drug to offer competition to the little blue pill.
Walgreens, which is based in the heart of Qwest, announced Monday that it will pay $1.35 million to settle a lawsuit filed by people who say their use of the drug led to their heart attack or stroke.
The suit, brought by people who say Pfizer’s Viagra triggered their heart attacks or strokes, comes amid growing pressure from government regulators to ban the drug after it was linked to fatal heart attacks.
The Food and Drug Administration last week approved sildenafil, the active ingredient in Viagra, for use in men over 50 but has faced challenges from some patients who say it causes birth defects.
The suit, filed Monday against a local representative for Walmart, names the company as the “maker of a generic version of Viagra,” according to an in- court release. The suit, filed Monday in the U. S. District Court for the District of Massachusetts, alleges that the company caused people to use sildenafil for erectile dysfunction.
The suit, filed Monday in federal court in Boston, is the first filed in the suit against Walmart by a defendant in a drug lawsuit over its use of sildenafil. Both products are sold in generic form, but Walmart has said it can no longer offer the generic version for sale.
Last month, Pfizer Inc. agreed to pay $1.35 million to settle a class-action lawsuit against it and other defendants. The settlement resolves nearly 15 years of litigation over Pfizer’s drug, Viagra, and the deaths of millions of people in the United States.
The settlement resolves nearly 15 years of litigation over Pfizer’s drug and other drugs. The lawsuit claims the company marketed sildenafil and other drugs for sexual dysfunction and promoted erectile dysfunction in other ways.
According to a in the suit, about 25,000 people who purchased Viagra, Pfizer’s version of the drug, between May 2007 and January 2009, developed erectile dysfunction. The lawsuit claims that about 25,000 people who purchased Viagra, Pfizer’s version of the drug between May 2007 and January 2009 developed erectile dysfunction.
Walgreens’ CEO Brian Hittner, who faces similar allegations, declined to comment.
The suit was first brought in 2016 by a group of people who claimed Pfizer’s Viagra caused them heart attacks or strokes.
The lawsuit is based on information provided by the FDA, which has been investigating the company’s safety.
The FDA, which is not responsible for Pfizer’s safety, has said that the drug has serious risks. The agency has also said it was concerned about some of the side effects of the drug, including an increased risk of strokes and an increased risk of heart attack and stroke-related death in some patients.
The FDA said that it was reviewing the information and will make any recommendations that it makes. The agency said that in 2016, it was reviewing data from a study that showed the FDA had found an increased risk of heart attacks and strokes in people who took sildenafil. The drug has not been linked to a fatal event.
According to the suit, the FDA had said it would not recommend the use of sildenafil by patients, as the drug could lead to serious side effects, including heart attacks and strokes.
In a statement, Walgreens said, “We are pleased to be able to pursue this matter and will continue to pursue all available options.”
Walmart has yet to respond to the lawsuit, but it faces questions about whether the company is likely to be successful in this case.
