Viagra Facts
For the treatment of erectile dysfunction, this medication is sold under the brand name of viagra and under the generic name of sildenafil. There are other uses and, in one case, a different brand name. The underlying mechanism is the same for all uses, working on the chemistry that causes arteries to dilate. Potentially, this would occur throughout the body. If it did, the result would be a sudden drop in blood pressure which could be dangerous. Thus, it is very important both to take the dosage prescribed by your doctor or recommended by the pharmacist, and not to mix this medication with others that also affect blood pressure.
How does Viagra work?
Viagra works with your body to help you get an erection. Viagra is a pill that works with your body to give your penis the boost it needs for sexual relations. Viagra is absorbed in your body, and pushes the blood to your private areas and then your body will respond to sexual stimulation to give you an erection.
Viagra is a medication that you take orally with any type of liquid about an hour before you think or that you want to have sex. If you are having dinner and going back to the apartment or to the house, you can take Viagra at the restaurant and when you get back home, you will be prepared for a sexual night with your partner.
When you take the Viagra pill, you won’t notice any reactions, you won’t get an erection without sexual stimulation. When your partner turns you on, or you are sexually stimulated another way, you will get an erection.
Brand Viagra
In 1990, Viagra was introduced and marketed by Pfizer in order to treat patients suffering from erectile dysfunction. The drug relaxes muscle to increase blood flow to the penis. But some how, researchers came to know the fact that the drug is also suitable for improving heart performance. You can find the drug from both online and local pharmacies.
Brand Viagra is made of Sildenafil citrate which relaxes the penile region and relieves pressure off the penile arteries. During the time of sexual stimulation, there is a rush of blood into these arteries which causes the penis to become erect. Brand Viagra encouraged erections are considered to be quality erections due to hardness, girth and elongated lasting.

How Viagra Professional Works
Viagra was discovered by accident. Originally it was being tested for its ability to cure angina. It didn’t help angina patients, but researchers found a different use for it.
When a man is aroused, his brain produces a chemical that increases blood flow to the penis. It does this by relaxing the muscles that hold the blood flow back and keep the penis in a relaxed state. Once the blood can readily flow, the penis gets erect.
Viagra treatment
Viagra is the first oral medication designed specifically to treat impotence. Known generically as sildenafil citrate, Viagra works by blocking an enzyme (PDE5), found in the penis, that breaks down a chemical (cyclic GMP), which is produced during sexual stimulation. The longer GMP remains available, the greater the chance of achieving and maintaining an erection. Unlike other drugs commonly used to treat impotence, which are addressed later in this chapter, Viagra does not cause an erection unless the man is sexually stimulated.
Viagra was tested on several thousand men with mild, moderate, or complete erectile dysfunction. These men had a broad range of conditions associated with ED, including high blood pressure, high cholesterol, diabetes, and prostate surgery. Viagra was effective in 50% to 80% of the men who participated in 21 clinical trials. Men with diabetes and those with a history of radical prostate surgery showed less improvement than other groups. No evidence suggests that Viagra enhances the sexual performance of healthy men.
Absorption and distribution
Viagra is rapidly absorbed. Maximum observed plasma concentrations are reached within 30 to 120 minutes (median 60 minutes) of oral dosing in the fasted state. When Viagra is taken with a high fat meal, the rate of absorption is reduced, with a mean delay in Tmax of 60 minutes and a mean reduction in Cmax of 29%. The mean steady state volume of distribution (Vss) for sildenafil is 105 L, indicating distribution into the tissues. Sildenafil and its major circulating N-desmethyl metabolite are both approximately 96% bound to plasma proteins. Protein binding is independent of total drug concentrations.

Viagra and the political economy of healthcare
An important focus of the media coverage of Viagra has been the drug’s macroeconomic impact. Viagra caused major ripples in the ongoing national debate over health insurance. Almost immediately, controversy raged over the status of erectile dysfunction as a health problem. Comparisons were made between Viagra and the birth control pill in the effort to point out glaring inconsistencies in policy making. In this section I look at two of the areas in which news stories reported Viagra’s impact on healthcare’s political economy: the debate over insurance coverage (including the inevitable comparison with the birth control pill) and Internet sales. Pharmaceutical sales on the Internet raise important questions about healthcare: specifically, the role of the physician - patient relationship.
Safety information
• Viagra may cause dizziness, blurred vision, fainting or lightheadedness. Do not drive, operate machinery, or other dangerous activities until you know how you react to Viagra. Using Viagra alone, with certain medicines or with alcohol may lessen your ability to drive or perform other complex tasks.
• To minimize dizziness or lightheadedness, sit up or stand slowly when rising from a seated or lying position.
• Viagra may rarely cause a painful penile erection, which can last for long periods of time and is not related to sexual activity. If not treated immediately, this may lead to permanent erectile dysfunction or impotence (not being able to have or maintain an erection for sexual purposes).
Viagra works with your body’s chemistry
Taking this medication, your body is going to be enabled to give you an erection and to keep an erection when you are sexually excited so you can perform sexually. Working with your body’s chemistry, Viagra allows your blood to flow to the penis creating an erection but only when your hormones relay that message to your body.
When you take Viagra you and you are aroused to get an erection, you can have an erection for up four to five hours. As you have quite a long time frame, you can have sexual intercourse for as long as you like during this time or until you are fully pleasured. Your erection will go away as it normally would after you are sexually satisfied.
