How does Viagra Tablet 25 mg work?
When a man becomes sexually aroused, his body releases nitric oxide (NO), which triggers the release of cyclic guanosine monophosphate (cGMP). These chemicals cause the blood vessels in the penis to dilate, allowing more blood to flow in and resulting in an erection. However, in men with ED, PDE5 breaks down cGMP too quickly, preventing the penis from staying erect.
Viagra Tablet 25 mg works by inhibiting the action of PDE5, which allows cGMP to accumulate in the penis. This results in improved blood flow and an erection that is firmer and lasts longer.
