Cardiovascular Considerations and Contraindications

A federal court judge ruled on Friday that the patent under dispute was valid and enforceable. The decision, which affects about $1 billion in U.S. sales of Viagra, is subject to appeal. The decision came as a surprise to analysts, most of whom had expected Viagra to lose market exclusivity in 2012.

• Viagra's quick onset makes it popular among users seeking spontaneity.
• The drug's contraindications include certain heart and eye conditions.
• Pfizer has developed generic versions when patents expired.
• Patients are advised to avoid high-fat meals to improve absorption.
• Viagra's use has expanded to include off-label pregnancy-related studies.
• The medication has been subject to numerous advertising campaigns.
• Pfizer invested in extensive post-marketing surveillance for Viagra.
• The safety profile of Viagra has been confirmed through long-term studies.
• Viagra influenced the rise of a broader market for sexual health drugs.

Pfizer's shares rose 2 percent to $18.23 in mid-morning trading on the New York Stock Exchange. The ruling comes as Pfizer braces for the loss later this year of market exclusivity for its biggest-selling product, the cholesterol-lowering drug Lipitor, which had 2010 sales of nearly $11 billion. "I think this is an important win for Pfizer," said Damien Conover, an analyst at Morningstar.

"This type of problem could happen to any large company with a system like this," said Jay Bolling, president of Roska Healthcare Advertising. "I do think Pfizer is the victim in this case. But at the same time, the company should acknowledge the problem and rally the public around trying to offset this problem in the future. It should also educate the users of the system." Bolling recommends that companies follow basic Internet maintenance, such as system updates, virus-prevention updates, and log-file reviews, to isolate data that is vulnerable. "A group like Pfizer really has to weigh security access when it has thousands of representatives running around the system, downloading various files, and being able to access things on its servers," Bolling said.

Each tablet contains 100mg of Sildenafil, a PDE5 inhibitor that enhances blood flow to the penis, helping to achieve and maintain an erection. Effective and fast-acting, Viagra 100mg provides reliable support for men's sexual health. "If you can hold on to $1 billion in sales of a high-margin product, that will definitely help offset the patent cliff Pfizer is facing." A spokeswoman for Teva declined to comment on the ruling. Analysts at Jefferies & Company estimate that the retention of U.S. Viagra sales is worth 3 percent to 4 percent in additional earnings per share. Viagra generated nearly $2 billion in worldwide sales in 2010, of which roughly half came from the United States.

Pfizer, the world's biggest drugmaker, said litigation on the same patent remains pending against other generic companies, but no trials are scheduled in those cases.

"Teva is considered the strongest among the generic drugmakers when it comes to litigation, so the fact that Teva lost this doesn't augur well for the smaller competitors that lack the legal resources that Teva has," said Les Funtleyder, a portfolio manager at Miller Tabak & Co, which owns Pfizer shares but not Teva's.

Add to that the unpalatable nature of the alternative treatments – either two vigorous hours with a vacuum pump before love making or multiple injections into the head of your penis – and it was clear that Viagra was a wonder drug. Within a year of Viagra’s successful launch Pfizer’s share price had doubled. Despite discovering the method for the mass production of penicillin, it was Viagra that made Pfizer’s corporate brand famous. But all good things come to an end. The European patent that has protected Viagra from copy-cat generic companies for more than a decade expired on Friday.

It’s the kind of nightmare that would keep most marketers up all night. Imagine losing your ability to protect your product formula, brand equity, most of your key accounts and your pricing strategy overnight. That is what it means to lose patent protection. Viagra will still be viagra online generic marketed by Pfizer in the UK and across Europe. But it will now face competition from more than 20 different generic manufacturers which will flood the market with identical versions of Sildenafil Citrate. Teva had challenged Pfizer's U.S.

method-of-treatment patent, which covers the indication for which the drug is used. The U.S. composition-of-matter patent is set to expire in March 2012. Typically, it is the cheap viagra online composition-of-matter patent that holds off competition. That Pfizer won the "use" patent may have something to do with its unusual development history.

The extra competition combined with the lower research and development costs of these generic players means that, aside from suddenly facing multiple competitors, the average price for treatment will drop from around £10 per pill to less than £1 within weeks. Like all good big pharma organisations, Pfizer has been expecting and planning for the loss of patent protection for several years. It will attempt to keep Viagra in the market, albeit at a lower price, and encourage patients to continue to request the drug by name thus side-stepping the generic threat. For patients prescribed the drug via the NHS, however, one or more of the generics will replace Viagra on the government tender, saving the UK taxpayer millions of pounds but eliminating one of Viagra’s biggest sources of patients. Pfizer will almost certainly introduce its own generic version of Sildenafil Citrate, codenamed ‘White Diamond’, this week in an attempt to retain market share among the new generic options.

Administration Notes

Whatever its strategy, the loss of Viagra’s patent protection will be very hard on Pfizer. When the company’s cholesterol treatment, Lipitor, lost its American patent in 2011 revenues declined by an eye-watering £4bn in a single year. There are only two long-term responses to the challenge of losing patent protection. First, optimise the brand while you have a patent. Unlike FMCG where brands often only reach their zenith 50 years after launch, big pharma marketers know they usually have only a 10-year window to make their profits and they act accordingly. Viagra, known also as sildenafil, was originally developed as a blood pressure treatment.

Chemical synthesis

Last week we witnessed a major turning point in the history of modern pharmaceuticals: Viagra came off patent in the UK. For the past 15 years, the impotence drug has generated billions for its manufacturer Pfizer. In 1990, the company had been testing a new blood pressure drug called Sildenafil Citrate at its research facility in Kent. Although its effects on high blood pressure were disappointing, doctors involved in the patient trials reported a fascinating, if unexpected, side effect. Many of the test patients, who had previously struggled to achieve and maintain erections, were experiencing an unexpected revitalisation in the downstairs department.

Why is the use of Viagra contraindicated with nitrates?

Further tests confirmed the result and in 1998 Pfizer went to its naming bank, picked the name Viagra and launched the drug with a massive fanfare of publicity. Pfizer knew it had a wonder drug but also that without strong marketing its success would be severely limited by the social stigma of impotence. So Pfizer created a new condition – erectile dysfunction – to imply that the problem was not the man but the penis, and that the penis could be easily fixed by Viagra. Approximately 10 per cent of the male population suffer from some form of erectile dysfunction; around 750,000 British men took Viagra last year. And because Viagra does not cure the disorder but merely treats it, Viagra’s lifetime value is just as impressive as its potential penetration. Sildenafil works by blocking an enzyme in the body called PDE5, which helps relax certain blood vessels. For erectile dysfunction, it increases blood flow to the penis when aroused. This makes it easier to get and keep an erection.

What is Viagra?

Second, make sure your product pipeline is ready with the next big blockbuster. Once the profit potential of an off-patent brand like Viagra begins to diminish, there has to be a new brand with a protectable formula waiting to explode from your pipeline. The big question keeping Pfizer up at night is not what it will now do about Viagra, but what it has that can possibly replace it. BOSTON (Reuters) - Pfizer Inc said on Monday it won a patent infringement case against the U.S. unit of Teva Pharmaceutical Industries Ltd, preventing Teva from launching a generic version of Pfizer's erectile dysfunction drug Viagra until October 2019. For pulmonary arterial hypertension, sildenafil relaxes the blood vessels in the lungs. This lowers blood pressure and reduces strain on the heart. 10 mg/mL powder for oral suspension 20 mg, 25 mg, 50 mg, 100 mg oral tablets Sildenafil is also available in an injectable form that is usually given by a healthcare provider in a hospital or clinic. Sildenafil oral tablets should be stored at room temperature, between 68 F to 77 F (20 C to 25 C). It can be exposed to temperatures between 59 F to 86 F (15 C to 30 C) for shorter periods of time, such as when transporting it. Sildenafil oral liquid should be stored at room temperature below 86 F (30 C) or in the refrigerator, between 36 F to 46 F (2 C to 8 C).
