What is Viagra?

Generic Viagra allows men to sustain an erection for sexual activity. It treats issues like impotence and erectile dysfunction. Most advise that you take a tablet of Sildenafil 60 minutes before sexual activity on an empty stomach.

Do not take more than once per day. Sildenafil is the active ingredient found in Viagra, and it is what gives men their erections. Patients can find this drug in 3 different forms including tablet, powder for suspension, and suspension.

Men and women from Singapore sometimes use Sildenafil to treat pulmonary arterial hypertension.

How Does Sildenafil Work?

Similar to other drugs that treat erectile dysfunction, Sildenafil belongs to a class of medicines that they refer to as phosphodiesterase 5 (PDE-5) inhibitors. Erectile dysfunction happens when the penis cannot get hard enough for sexual activity. It no longer expands when a man feels sexually excited because the blood flow to his penis doesn’t work in the normal way.

To get around this problem, Sildenafil blocks the enzyme known as phosphodiesterase type-5 from going into action too quickly, which prevents a male from getting and sustaining an erection. Important to note, this drug only works when the patient feels sexually aroused. While it may help one to get an erection, it does not give them the erection.
