Viagra is an extremely well-known name brand drug that is used to treat pulmonary arterial hypertension and erectile dysfunction (the inability to attain or maintain an erection) in men. It was the first drug known to treat impotence, though it began as a way to treat pulmonary issues, and was made readily available in 1998 by Pfizer Inc. It has been studied in more than 23,000 men with Erectile Dysfunction, which affects about 30 million men in the U.S.

The name of the drug branded as Viagra is Sildenafil, it is a small, blue tablet that enhances the erectile response to stimulation by relaxing the blood vessels in the penis and allowing blood to flow more freely, allowing for longer-lasting erections. When you are sexually stimulated, visually, physically, or otherwise, your nervous system release nitric oxide. Nitric oxide stimulates an enzyme that produces something known as cGMP, cyclic guanosine monophosphate, which relaxes smooth muscle cells. Viagra maintains the levels of cGMP, allowing the arteries in the penis to dilate and the erectile tissue to fill itself with blood, thus attaining an erection.

The amount you must take at once will be prescribed by a doctor but it is usually administered in one 25 mg, 50 mg, or 100 mg tablet a day. You must take the tablet one hour before you expect to require it for sexual intercourse, it can sometimes take longer if taken after a heavy meal.

Although it can vary, Viagra has been known to sustain an erection for up to five hours, although two to three hours is the more typical amount of time. You should always talk to your doctor about any medical conditions you have, other medications you are using, diet, allergies, and any side-effects you experience while taking Viagra. If your erection lasts a longer or shorter time than expected, you should contact your doctor.

Usual side-effects include headache, facial flushing, nasal congestion, nausea, stomach pain, rash, UTIs, diarrhea, and a blue tint to your vision. Viagra can slightly lower your blood pressure, but this is not uncommon nor is it dangerous. However, you should never take Viagra if you also take any nitrates, used in the treatment of chest pain and pulmonary hypertension, as the combination can lower your blood pressure too much and it can be fatal. Nitrates are used in treatment of angina.

The price you can expect to pay depends on how many tablets you will be buying, in what amounts, and where in the world you are located. In general, major US pharmacy chains in Pretoria sell 50mg of Viagra for $22 to $24 per tablet, unless Viagra has been prescribed to you and is covered by your insurance. Despite rumors to the contrary, Viagra is not licensed for use by women and has never been proven to have any effect on Female Sexual Dysfunction of any kind.

Every year, it makes more than $1 billion in sales in the US. As of 2017, Pfizer Inc. will begin selling a generic form of Viagra, marketed only as Sildenafil, a small white pill to Viagra’s blue.
