Viagra online Australia

Viagra online is primarily a vasodilator. This medicine can magnify the flow of blood to the pelvic region by dilating the vessels leading to it. When the blood vessels get expanded, the more blood passes through them and fills into the penis. The veins within the penis trap the blow until the climax. When the climax is reached the blood goes away from the penis.Viagra online
The mechanism of Viagra action involves many important processes. The onset of erection is urged with sexual stimulation which helps to increase the amount of nitric oxide in the penile region. This substance is essential for the erection to occur. Sildenafil, the main component in Viagra selectively inhibits the enzyme PDE-5 which is located in the tissues of the penis. This enzyme affects the cGMP, the other important substance which regulates smooth muscle relaxation. If there is too much of PDE-5 in the penile tissue, a man experiences weak or no erections as this enzyme prevents the normal blood flow to the penis. By inhibiting PDE-5, Sildenafil fosters the erectile process. More blood flows to the penis due to relaxed smooth muscles. Once it happens a man has stiff and hard erection.

Several studies of Sildenafil were conducted in patients with different ED causes, physical and psychological including patients with diabetes mellitus, nerve damage, hypertension, heart disease and atherosclerosis. In eight double-blind placebo-controlled crossover studies of the drug in patients with diagnosed impotence, the sexual arousal in men after dosing led to improved erectile function.

The improvements in erectile function were estimated with an objective measuring tool RigiScan. The erections were assessed in two main positions: the duration and the rigidity. Besides, men taking part in these studies were asked to make self-assessment after using Viagra.

Most studies observed that the medication was effective about 45-60 minutes after dose, still some patients had sexual response 15 minutes post dose.

The erectile response assessed by RigiScan was increasing with the dose enlargement as plasma concentration of the drug increased.

The duration of the drug was up to 4 hours.
