LONDON (Reuters) - Pfizer Inc's drug Viagra lost its best-selling patent on Wednesday, making it the world's most successful medicine. Pfizer had already lost patent on its blockbuster erectile dysfunction drug Cialis, but the drug now has the most to offer, with the best-selling drug costing around half the price. The results were announced by Pfizer's Chief Executive Officer Albert Bourla, who has been in the market for years and has been keen to maintain the company's top-selling product.
The loss of patent on Cialis, which is about half a year after the original patent ran out, could save the company from being hit with an initial patent loss. Cialis is not the only drug that Pfizer has lost patent, with the patent on the heart drug Viagra losing protection against a possible US Food and Drug Administration (FDA) approval in December. A similar patent, made by Pfizer Inc to treat angina, was not affected by the loss of patent.
Viagra lost patent on patent applications in June, which were still in place, after a similar patent application was granted in November last year. In the US, Pfizer's patent on the drug for treatment of erectile dysfunction was upheld and Pfizer has won approval for the use of Viagra. Pfizer has been able to get Viagra for around three years after patent application expiry, which was on Friday.
"Pfizer lost the opportunity to continue its long-standing history of innovation and innovation and now has the highest-than-average market for Cialis," Bourla told Reuters.
"We're very proud of Albert for keeping his position as a leader in the industry, and we look forward to continuing to work with him to secure the best possible outcome for our shareholders."
Pfizer had lost the patent on Cialis in May this year. The patent was set to expire in November but the patent holder Pfizer said it would continue to market the drug until the patent expired in March.
The patent on erectile dysfunction (ED) is already in force in the US, where it is the best-selling medicine in the world.
In a statement, Pfizer said: "We are pleased with the outcome of the patent litigation and the ongoing work of the US Food and Drug Administration (FDA) on patent infringement litigation (and the subsequent) and we look forward to continuing our commitment to market our products and delivering a reliable product to our shareholders."
Pfizer said the company would continue to market Viagra until the patent expired in March.
Viagra was the most expensive drug in history and currently accounts for one-fifth of the company's total annual revenue. It's the world's most valuable drug, with a record $7 billion in sales.
For a generic version of the drug, Bayer's patent on Viagra expired in April. The patent on the generic version has not yet expired, but plans are in place to extend the patent on Viagra to cover the generic version, which was not affected by the loss of patent.
Other major companies like Teva Pharmaceutical Industries and Sun Pharmaceutical Industries will also be affected by the loss of Viagra. It will be made available for purchase by patients in late-stage trials, and Sun Pharmaceutical Industries is seeking a royalty for the use of its product, but it will not be allowed to continue selling it until the patent expires.
Pfizer said that it was "remaining focused on delivering a high-quality, reliable and effective product to shareholders and patients", as well as focusing on developing a new product. It was also looking at developing a product that could be used as a substitute to Viagra, which it has recently launched for the treatment of erectile dysfunction.
Sildenafil, the active ingredient in Viagra, is also a drug for treating erectile dysfunction and has been in use for a long time. It has been approved by the US Food and Drug Administration (FDA) for use as an oral medication. The FDA has approved sildenafil in March.
Cialis lost patent on patent applications for Cialis in June and is now available to buy online from the pharmacy without a prescription in the US. Cialis is a prescription-only drug, which means it cannot be purchased over the counter.
Pfizer's chief executive officer Albert BourlaThe company said the loss of the best-selling patent on Cialis would enable it to maintain its position as one of the world's most successful medicines by the end of the year.

Do not use the live feed please.It’s a tough decision to make for those who live in the Philippines. But a new trend, which has led to a rise in fake Viagra, has made it easier for men to buy it. So far, the drug has been available to millions of men in India and Singapore, though it is not yet available in all of the countries.
Viagra is often sold under the brand name “Sildenafil,” a prescription drug used to treat erectile dysfunction. In India, it’s known as Viagra, while in Singapore, it’s known as Sildenafil.
In the Philippines, the country’s first online pharmacy, Dr. Reddy’s, is currently offering its own drug, Viagra. They’ve got the drug in its formulary, a form of the generic medicine.
Viagra is known as a popular drug for erectile dysfunction, as it can be easily absorbed through the skin and can be taken before sexual intercourse. But it is not yet available in all of the countries.
Dr. Reddy’s is also offering its own drug, “Blue Diamond,” which was originally designed as a remedy for impotence in men. But it has been found to cause erectile dysfunction by a different group of people. So it’s important to know which drug is available in the Philippines and which isn’t.
Reddy’s, a leading online pharmacy, is one of the most popular pharmaceutical companies in the country.
The drug, available as an over-the-counter drug, is called Viagra. Viagra is the active ingredient in the original prescription medication, Viagra. The company’s patent expired in 2016, but the drug was still under development.
But this new drug is still in development, which has allowed it to be sold in the Philippines in the form of a medicine.
The company’s latest competitor is known as Dr. Reddy’s, which was also a popular drug for impotence.
Reddy’s is also offering its own medicine, “Nigeria 10,” which contains the same active ingredient as Viagra.

According to, a survey by the IPC, the country’s pharmaceutical industry said it has seen more than 10 percent of the population use it.
However, the country’s pharmaceutical industry has been unable to differentiate between its own medicine and its own. This is due to various factors including poor regulation of drug sales, lack of awareness of the health and safety issues, and the fact that the country is now facing a lack of quality drugs.
But while Viagra is available over the counter in many countries, Nigeria is the only country that can provide a prescription to its patients for its generic drug. And there are other drugs available on the market to treat impotence, like.
The company is also seeking to introduce its own drug as an alternative to Viagra, called “Sildenafil”.
Sildenafil was developed by the pharmaceutical company, which makes Viagra.
But unlike Viagra, which has a long history of being used for ED, Sildenafil has no long-term side effects. It is used for the treatment of erectile dysfunction, not for other conditions.
This makes it a more accessible drug for men who want to try it, which is why many men in the Philippines are looking to buy it.
And in the Philippines, there are other products available such as vitamins and supplements. In India, for example, there are several, a type of vitamin called, which is a type of vitamin that can help men maintain a healthy body weight.
