Used in the treatment of erectile dysfunction (ED), Sildenafil belongs to a group of medicines called PDE5 inhibitors. These drugs prevent an enzyme called phosphodiesterase type-5 from working too fast. In turn, this makes it easier to get and maintain an erection during sexual stimulation. Note that many patients suffering from the cardiovascular disease should consult a physician before using this treatment or related medicines.
Sildenafil citrate is the active ingredient in Viagra and is available in a generic, unbranded tablet. Sildenafil and Viagra are medically equivalent but Sildenafil is available at a much lower cost.
The medicine works by relaxing the muscles in the veins that carry blood to the penis. By doing this, it promotes increased blood flow, making it possible to get an erection during sexual excitation. Contrary to popular belief, the treatment does not cause spontaneous erections or have any effect on your sexual desire. You must be sexually aroused to get an erection using Sildenafil.
It is important to be aware that PDE5 inhibitors do not treat the underlying causes of ED, which can include physical problems such as diabetes and high blood pressure, and psychological issues like anxiety and depression. Because of this, it is important to seek medical advice to find out why you are experiencing ED.
