Sildenafil – A Basic Idea About This Generic Drug Substance
- Sildenafil is the first of its kind to be approved by the global drug-approving body, the US FDA, for the treatment of erectile dysfunction.
- In case you do not have an idea of what ED is, it is a potential disability that cuts down the ability of men to have a strong and consistent erection. Without the ability to get a hard erection, men lose their penetration ability and thus cannot have sex.
- However, it is with the help of viagra that one potentially recovers from this disability. It brings you close to your normal sex life once again, as you can get a strong erection pretty fast.
- We will tell you about the effects of Sildenafil later on, but for now, remember that it comes from a class of drugs known as the PDE-5 inhibitors.
- It is a prescription element. So, regardless of the brand of sildenafil you are buying, you will always need a prescription from a doctor first.

Effects Of Sildenafil
Sildenafil, as we told you above, can change the failure of penis erections. It can do so with its action on the PDE-5 hormones initially, which it suppresses completely.
On the suppression of the PDE-5 hormones, the gateway to the cGMP hormones opens, and it increases in the blood.
Soon, it is also able to activate nitric oxide, whose action is quite important in the process of getting you a hard erection. The fixed role of nitric oxide is to cause dilation, because of which the arteries relax and there is an increase in the flow of blood to the penis tissues.
Because of this, you are easily able to get more sensitivity in the penis area because you get a hard erection each time during stimulation.
