What is Viagra?
Viagra, active ingredient sildenafil, is a prescription medication used for treating erectile dysfunction. Manufactured and marketed by Pfizer the drug has helped treat ED in millions of men all over the world.
How does Viagra treat ED?
The active ingredient, sildenafil, is a phosphodiesterase type 5 inhibitor also known as PDE5. The inhibition of PDE5 (responsible for the breaking down of cGMP) helps improve the levels of cyclic guanosine monophosphate (cGMP), which in turn helps dilate your blood vessels and improve blood flow. This results in a firmer erection and also helps you maintain the erection.
What are the doses of Viagra?
Viagra is available in the doses of 25mg, 50mg and 100mg. Typically, a dose of 50mg is prescribed, but if you are 65 years and older or suffer from some serious health risks, a lower dosage of 25mg can be prescribed.
How often should Viagra be taken?
A single dosage of this medication needs to be taken one hour before sex. The effect of this medication lasts in the body for around 4 hours.
