Both Viagra and sildenafil are widely used to treat erectile dysfunction. In fact, they contain the same active ingredient. Viagra is a brand name for the sildenafil produced and sold by the company Pfizer. Sildenafil is also sold as a generic drug, which is medically identical to Viagra.
Sildenafil citrate was Albert Wood and Peter Dunn as a possible treatment for hypertension and angina; conditions associated with coronary heart disease. In 1991 Dr. Nicholas Terrett, now often referred to as the father of Viagra, was named in the British patent for the drug as a heart medication. And though Pfizer’s early trials of the drug in the 1990s did not prove its efficacy as a heart medication, patients who took part in the clinical trials reported increased erections after taking sildenafil. Separate studies provided more information on the biochemical process that causes erections, which helped scientists understand how sildenafil could enhance the effects of sexual stimulation and open up blood vessels in the penis. Sildenafil was then studied in men with erectile dysfunction, and in 1998 it was approved by the FDA specifically for treatment of ED and branded as Viagra.
When for the drug in June 2013 it made way for generic manufacturers to produce sildenafil, or ‘generic Viagra’. It costs a fraction of the price of Viagra, and has made the treatment more accessible to a wider range of patients. You can now choose to buy, Pfizer’s branded drug, or, the generic version.
Branded Viagra comes in small diamond-shaped blue pills – Pfizer has also patented this pill design and appearance. Sildenafil is sold as white or blue tablets, with different characteristics depending on the brand. Some have chalky finishes while others are smooth, and some are scored for easy division, while others are not. Both Viagra and the different can be purchased in 25mg, 50mg, and 100mg preparations, and there is no significant difference between them in terms of active ingredients.

Sildenafil tablets can come in many shapes, colours, and sizes – see.As a generic medicine, sildenafil is produced by a number of manufacturers, and competition among them helps to regulate its price and keep it affordable for consumers. Branded Viagra is only produced by Pfizer, whose name recognition and customer loyalty allow it to charge a higher price for its renowned ‘little blue pills’.
Viagra and sildenafil are medically the same. It is a requirement for the generic version to contain the same levels of the active ingredient in the body as its branded alternative, which is known as. Before generic drugs are licenced for sale the manufacturer must demonstrate bioequivalence to the licensing authorities (the ).

It's the first drug designed to treat erectile dysfunction and to lower blood pressure, but it may be a little too soon for some people. Viagra's US patent was set to expire on June 13th, 1998, in the United States. The drug is made by Pfizer, which was acquired by Cipla in 2003.

Some pharmacies offer a Canadian prescription for sildenafil to treat erectile dysfunction.
The patent on sildenafil is based on the patent of PDE-5 inhibitors, which works by relaxing blood vessels. It's also called "sildenafil" because the drug works by increasing blood flow to the penis. Viagra, while not approved by the Food and Drug Administration for the treatment of erectile dysfunction, is a prescription-only drug for this purpose. Viagra works by improving blood flow to the penis.

As the drug maker adjusts to lose its patent protection in December, Pfizer's new chief executive has revealed a plan to stop making erectile dysfunction drugs, which are the world's most popular drugs, for a year to come.
The company is still working on a strategy to bring down costs, according to the Wall Street Journal.
In December, the company said it was cutting a key part of the company's strategy to increase revenue, which includes creating a pipeline of new drugs, including Viagra and Cialis, which are used to treat erectile dysfunction. As Pfizer gets off the drugs, the company is looking for ways to boost sales.
Pfizer has been selling the drugs on the black market, but a major market for these drugs is in China, which it has bought for $100 billion, the Journal said.
Pfizer said it was losing its patent on Viagra for the treatment of erectile dysfunction.
It added that the company had to stop making the drugs because Pfizer is looking for new products, and that it would no longer sell the drugs in Europe. Pfizer is also losing its patent on Cialis for erectile dysfunction.
Pfizer said that in the future, it would be able to make Cialis more widely available to patients who have serious medical conditions and who do not have the disease. It will also be able to make its Cialis patent on Viagra available to patients who have serious medical conditions, the Journal said.
The pharmaceutical company said that although the market for erectile dysfunction drugs is expected to grow, Pfizer has still not launched a generic version of the drug, and that the company is hoping to add new drugs in the pipeline.
Pfizer also said that its sales of Viagra and Cialis for the treatment of erectile dysfunction will go down as the company loses patent protection for Cialis, which is currently patented in Europe for Viagra.
In a statement, Pfizer said that its plans to buy Pfizer's worldwide sales of Viagra will be closely watched.
"Pfizer has been working to address the challenge of erectile dysfunction, but it is not clear what type of product it is looking for," the company said. "The launch of Cialis in the U. S. and the new drug in the U. K. is expected to be a major step toward addressing the challenge of erectile dysfunction."
The company said that it has worked with Pfizer on a number of other strategic initiatives, including developing new products in the U. and Europe and is working with a number of partners to increase its presence in the erectile dysfunction market.
The New York Times' Steve Doherty contributed to this report.

The new drug is a treatment for enlarged prostates. A study of Viagra's effect on patients has found that it can help improve erectile function.
In the study, more than 80 percent of patients who had erectile dysfunction were able to achieve an erection, and 40 percent had no problems with their erections. A second study, published in December, found that men with ED were much more likely to have an erection that lasted more than four hours.
The new drug is expected to be a big part of the company's growing effort to bring down costs for Viagra, Cialis and other erectile dysfunction drugs.
The drugs' main ingredient is sildenafil citrate, a drug used to treat erectile dysfunction.
