What is Viagra
Viagra is the most popular form of treatment solution for erectile dysfunction that is patent owned by Pfeizer. The main effect of it is to enhance penile erection during sexual stimulation. It is considered to be a successful and effective solution for impotence in men. The drug is approved by the Food and Drug Administration (FDA) and is known to be safe and effective.

The discovery of Viagra is one incidental to the clinical research study of a clinical research team on the potential of Sildenafil citrate in treating angina among cardiovascular patients. Unfortunately, Sildenafil has very minimal effect in treating angina. However, it was noted that Sildenafil has a powerful action in potentially improving the blood flow in the body that is strong enough to facilitate an effective penile erection. Focus in the therapeutic effect of Sildenafil thus shifted from treating angina into treating erectile dysfunction. It was Pfeizer that was able to first obtain the patent ownership of Viagra in the market.

Viagra is a prescription drug that requires an evaluation of your condition by a doctor before taking it. Although the drug is mainly prescribed for men suffering from erectile dysfunction or those with inability to sustain prolonged penile erection, it is necessary to have yourself evaluated by a doctor if Viagra is safe for you to use. It, just like the other synthetic drugs, has minor side effects that are usually mild and tolerable.

Common side effects that are reported in the use of Viagra include blurred vision, faintness, headache, nasal decongestion, flushing and nausea. In some rare cases, men taking Sildenafil citrate would experience diarrhea, rashes, muscular and joint pains. In rare cases, serious complications would occur especially when it is taken with other drugs and alcohol intake. It is not also safe to take Viagra when you have a medical condition that would produce complications once you take it. While Sildenafil is generally safe to take, it is necessary that the drug is taken according to a doctor’s prescription in order to maximize its effects and prevent possible complications and side effects when taken without consulting a physician.

Viagra is available in dosages of 25 mg, 50 mg, 100 mg and 150 mg. Your doctor will give you the appropriate dosage according to your needs after an evaluation has been made. It is necessary to take the drug accordingly as prescribed by your doctor.

Viagra is an effective drug for impotence. It produces a natural effect of causing penile erection not by directly causing this physiologic reflex of erection but rather enhancing the action of the nitric oxide which is responsible for causing good flow of blood into the penile smooth muscles that naturally causes erection to occur. Because it provides a solution to men’s long problem with impotence, it helps to improve their sexual function and performance. It also promotes better sexual relationships between couples. Aside from the benefits of treating erectile dysfunction, Viagra also provide health benefits in improving medical conditions involving the heart and lungs, diabetes, fetal care and in building muscles.
