What is Viagra Sildenafil and what exactly does it do?
When you buy Viagra you are buying into a medical technology that has been tried and tested for over ten years. Viagra was the first breakthrough impotence treatment of its kind, making it the first PDE5 inhibitor available back in 1998. By inhibiting PDE5 in the blood, the enzyme that normally increases the flow out of the penis is not broken down. Instead it builds up. By building up the blood does not flow from the penis, but instead into it. This in turn causes large, firm erections where in the past the person with impotence would have not been able to even get an erection.
The active ingredient in Viagra is Sildenafil Citrate. Made by Pfizer and introduced onto the market in 1998, Viagra has become the most popular, trusted and sought after impotence pill on the market. 78% of men who have used it have found it successful. It works in response to sexual stimulation, which explains literally that it is designed to work with your bodily processes to improve your sexual performance. Men who take Viagra before sexual intercourse can expect to get and attain an erection for long enough to complete satisfactory sex within four hours of taking the little blue pill.
Who can use Viagra Sildenafil and how do you use it?
Viagra is a prescription only medication, so when you buy Viagra, you cannot necessarily do so directly over the counter. Before buying Viagra you need to visit a doctor or do a legitimate online consultation. The reason for this is for the doctor to gather relevant information on your medical and health background. Providing the doctor is happy after your online consultation and deems Viagra suitable for you, he will write out a prescription with a suggested dose. You could get any of three doses, 25mg, 50mg or 100mg. You can use the prescription to buy Viagra at any online or regular pharmacy. It is important to be aware of who and where you are buying Viagra from, to avoid buying fraudulent products.
Viagra is only effective if taken when you are sexually stimulated. Because of its methods, it needs the brain to send certain signals to specific parts of your body for the active ingredient, Sildenafil, to work. It will not work if you are not sexually stimulated. It should be taken roughly an hour before sex and lasts for up to four hours in the body. Generally anyone can take it, but as previously mentioned, it is only available after consulting with a trained doctor and getting a prescription. The smaller the dose, the more minimal the side effects. If you do experience side effects, they may be indigestion, headache or a bluish/blurred tint to your vision.
