Viagra is one of the most popular drugs in the world for the treatment of impotence in men, a condition also known as erectile dysfunction. This drug is the best known since the mid-nineties when it was released.
In Australia, men who take Viagra are satisfied with the results in the short and long term. But behind this drug is a interesting story, facts and a scientific group that discovered the use of Viagra by accident.
Who is the creator of Viagra?
This drug is popular in Australia, but was invented in England in the last decade of the 20th century. During an investigation to treat heart problems and chest pains, scientists discovered a strange side effect in clinical trials of phosphodiesterase type 5 inhibitors. The side effect in men were erections 30 minutes after taking the drug.
The laboratory behind Viagra is Pfizer. The drug was patented in 1996 in most countries such as UK, United States and European territories. In Australia the drug was first marketed by the Pfizer in 2000.
What is the main component of this drug?
As mentioned earlier the name of the drug in the laboratory was phosphodiesterase type 5 inhibitors, a drug designed to treat problems such as Angina (chest pain) and hypertension.
The trade name of this drug is Viagra, but the component is known as Sildenafil Citrate. That same component is found in other similar drugs on the market for the treatment of erectile dysfunction in Australia.
How does Viagra work to treat erectile dysfunction?
This drug is not a final solution for ED. But in Australia, this drug has served as an aid to lead a sexual life with more freedom and without impotence problems. What Viagra does is dilated and relax the blood vessels in the penis to maximize blood flow. Once the blood flow improves, the erections will be instantaneous for the desired time.
Is there any risk for taking Viagra?
Like any drug, risks always exist when consuming more than the recommended dose. In Australia doctors recommend taking a single daily dose of Viagra minutes before sexual activity.
The side effects that some men suffer from taking Viagra are: headache, vomiting, loss of balance, dry mouth. Other more severe side effects are due to excessive consumption of Viagra: temporary blindness, hearing loss, cardiac arrhythmia.
Where can you buy Viagra in Australia?
Men mostly buy Viagra at pharmacies. But it is also possible to buy Viagra online on the internet. Most online stores offer authentic products licensed by Pfizer. Some of those stores are:

The future of Viagra in Australia and in the global market.
Pfizer as the owner of the patent for this drug faces stiff commercial competition with other laboratories that offer other similar drugs for the treatment of ED. In 2020, Pfizer will lose the official Viagra patent on all components of the drug. This will cause a drop in the prices of Viagra and other drugs with Sildenafil Citrate as the main component.
It is expected that by 2020 this and other drugs will lower their prices considerably in Australia and other parts of the world. Men will have access to other options with low prices but with Viagra as the top number one option.
