What is viagra used for?
비아그라 구입 fights against male erectile dysfunction.
We define impotence as the inability to maintain an erection that is hard enough to provide satisfactory sexual intercourse.
Remember that viagra increases blood flow in the penis, but does not make the member erect without sexual arousal. For this to occur, the product acts by inhibiting the PDE5 enzyme (phosphodiesterase type 5).
Its operation is simple.
Viagra interferes with the blood process that stops the erection of the penis. And PDE5 is the enzyme responsible for this disruption. It works by relaxing the muscles and veins in the penis enough to allow blood flow to return to normal.
In general, the enzyme is important, as it has a regulatory function. The problem occurs when PDE5 is so strong that it stops erections before they even start. Thus, sildenafil, the active ingredient in Viagra, belongs to a family of substances called “PDE5 inhibitors”. Inhibitors stop PDE5 from working, allowing you to have a proper erection.
How to use viagra?
Important: This medication should only be used when recommended by a doctor (preferably a urologist). The professional will assess, for example, if you do not have contraindications that prevent you from taking Viagra safely.
Also, do not buy directly from websites not linked to regulated pharmacies: you will be exposed to illegal websites and fakes.
You must respect what has been prescribed by your doctor and follow the instructions on the medication package insert. Therefore, do not take larger doses than your doctor has recommended.
비아그라 can help you to get an erection during sexual intercourse, but an erection will not occur simply by taking a pill under any circumstances.
