What is Viagra?Viagra is a prescription drug used to treat erectile dysfunction (ED).
Viagra is the generic version of the erectile dysfunction drug sildenafil. Viagra is a phosphodiesterase (PDE) inhibitor. The active compound in Viagra is sildenafil, which works by relaxing the blood vessels in the penis, thereby increasing blood flow into the penis. Sildenafil relaxes the blood vessels, allowing blood to flow into the penis when sexually aroused.
Viagra is a brand name for sildenafil. It is a generic version of the drug Viagra.
How does it work?Viagra and sildenafil work in similar ways. Viagra increases the blood flow in the penis when sexually aroused. This increased blood flow causes the smooth muscle cells of the penis to relax, allowing the blood to flow into the penis. Viagra also increases the blood flow in the genital area, resulting in increased sensitivity to sexual arousal. Sildenafil helps to improve blood flow in the penis, but its effects can vary from person to person.
Who can use it?Sildenafil is approved by the FDA to treat ED. The drug is only available with a prescription. Doctors may prescribe Viagra for other purposes, including treating pulmonary hypertension. However, the FDA requires that the drug be taken only by those with certain medical conditions.
What are the side effects?Viagra and sildenafil can cause mild and serious side effects. They include headaches, flushing, indigestion, nasal congestion, dizziness, vision changes, and muscle pain. Serious side effects may occur if you take more than the recommended dose. If you have severe side effects, seek medical help immediately. Serious side effects may include priapism (a prolonged erection), chest pain, vision changes, and an erection that lasts longer than four hours. Seek medical attention if you experience these symptoms.
Can I take it if I am pregnant?Sildenafil is not approved for use during pregnancy. It is not recommended for use during breastfeeding. It is not known if sildenafil passes into breast milk. It is not approved for use during breastfeeding.

WASHINGTON, Feb 28 (Reuters) - South Africa's drug giant Pfizer's Viagra is now looking to sell it as a cheaper alternative to the popular erectile dysfunction drug Viagra, officials said on Tuesday.
Viagra, which was the world's biggest seller in 1998, is still widely considered a miracle drug for treating erectile dysfunction, but officials are now looking to sell it in other countries, with a view to selling the drug in Europe.
Pfizer, which makes the world's largest generic drug company, has been selling the pill in South Africa for months, but the company is hoping to sell it in other countries in the region.
Pfizer has not given a specific date on its plans for selling the drug, but the firm is hoping to sell it in other countries around the world. The drug, which is in a class of medicines known as PDE-5 inhibitors, has been banned in some countries due to its side-effects.
Viagra has been approved by the Food and Drug Administration, but it is only approved for the treatment of erectile dysfunction, which is usually caused by insufficient blood flow.
"This was the first time in a year that a drug had been approved in South Africa," said one Pfizer executive.
The erectile dysfunction drug was originally developed to treat patients with pulmonary arterial hypertension, but it was later discovered to be ineffective for this use. PDE-5 inhibitors work by blocking the action of an enzyme known as cyclic guanosine monophosphate (cGMP), which leads to relaxation of blood vessels.
The erectile dysfunction drug is sometimes referred to as Viagra or as the "little blue pill," but the FDA has not approved it for use in South Africa and the drug has not been banned in some other countries.
Pfizer and other big drug manufacturers are planning to make a similar drug, called Sildenafil Citrate, available for sale in some European countries.
Viagra will be available by prescription only in some European countries.
Pfizer said it was also looking to make the drug in other countries in the region. The drug is not currently in clinical trials in South Africa and is not expected to be approved by the FDA until next year.
The drug was developed in South Africa and is marketed in the U. S., Europe, Canada, the Middle East, Africa and Japan.
In a, Pfizer said it was working on a new medicine that would help men who struggle to get or keep an erection when they are sexually stimulated. The new medicine would treat impotence and also treat other conditions such as erectile dysfunction.
Pfizer will also sell its version of Viagra in the U. S., Europe and Canada.
Pfizer's patent on Viagra expired in April 2006, but the patent has been renewed for up to $20 billion.
Viagra is still the world's biggest drug by sales.
Pfizer has been buying the world's largest drug company for years, but it has decided not to sell the drug.
Pfizer's Viagra would be sold at a cost of $100 a tablet, or about $0.47, in some European countries.
Pfizer is not the first drug company to be forced into over-the-counter sales of Viagra and other erectile dysfunction drugs, according to the World Anti-Doping Agency.
The U. S. banned Viagra from the world in 1998, and the FDA has approved sildenafil, the generic form of Viagra, for use in the U.
In 2005, the FDA approved a version of sildenafil called Sildenafil Citrate (the active ingredient in Viagra) for use in the U. S., according to Pfizer.

The announcement comes after a series of European regulators in the United States seized millions of euros worth of Viagra in Europe last year. The drug was first approved for use in Europe in 1998 and is a common treatment for the symptoms of erectile dysfunction.
The European Commission is also currently considering the drug’s development. The drug was first developed by Pfizer’s pharmaceutical company in 1990.
In addition to being a prescription-only medicine, Viagra is also marketed in the European Union. The drug contains sildenafil, the same active ingredient in Viagra as the drug’s active ingredient, Viagra. It was approved for use in the EU in 2006.
The Commission issued a statement declaring that the drug was “currently on patent protection in the EU and is therefore a prescription only medicine.”
The statement went on to say that “Viagra is a prescription only drug that is available in the EU.”
Viagra is the “only” drug on the market in the EU that is prescribed by doctors for the treatment of erectile dysfunction. It was the first medicine that was approved for the treatment of this condition. However, in July, the US Food and Drug Administration rejected the drug because the FDA’s own review found that the drug is not approved for the treatment of the signs and symptoms of benign prostatic hyperplasia.
In April, the US Food and Drug Administration said it had found the drug has no risk of causing serious problems in children. The FDA’s review found no risk to the developing child.
The US company said that it had reviewed more than 100 million tablets of Viagra in 2016. It was not clear how many were counterfeit and of how many people had taken the drug. Pfizer, the manufacturer of Viagra, was the last to receive approval for the drug in the United States.
The US company said that it was working with regulatory authorities to make sure that the drug is safe and effective. It has also urged the European Commission to make sure that the drug is approved for the treatment of erectile dysfunction.
According to the company, “In response to the reports of counterfeit Viagra that were received from the US, European regulators have advised patients and healthcare providers to avoid taking this drug and to consult their doctor before taking Viagra.”
Viagra is the only medicine on the market that has a patent on its active ingredient. Pfizer said it has “received regulatory approval for Viagra and is in the process of obtaining a license for it.”According to the company, the drug “will continue to be a ‘prescription only medicine’ until the patent expires.”
The drug was approved for use in Europe in 2006, but has yet to be approved for the treatment of other conditions.
