Here we look at all you could need to know about 비아그라 (viagra).
What Is Viagra?
Viagra is a brandname name for the medication sildenafil citrate. The active component, sildenafil, belongs to a class of drugs referred to as phosphodiesterase-5 (PDE-5) inhibitors which work by increasing blood flow to the penis. This helps men achieve and maintain an erection when they are aroused. It should be noted that ED may be brought on by physical or psychological issues, so it's important to speak along with your doctor before beginning any kind of treatment plan.
How Does It Work?
Each time a man becomes aroused, his body releases nitric oxide in to the bloodstream. Nitric oxide activates an enzyme called guanylyl cyclase which produces guanosine monophosphate (GMP). GMP relaxes smooth muscle cells in the corpus cavernosum—the spongy tissue forming the walls of the penis—which in turn causes increased blood flow to the penis causing an erection. PDE-5 stops working GMP preventing this technique from happening, however viagra works by inhibiting PDE-5 allowing GMP levels to increase leading to an erection when aroused.
Viagra's Side Effects While there are numerous advantages to taking viagra, there are also potential negative effects connected with it as well. The most common negative effects include headaches, flushing, dizziness, indigestion, nasal congestion, back pain and blurred vision. In rare cases more serious side effects can occur such as for example priapism—an erection lasting over 4 hours—coronary arrest or stroke. If you feel some of these much more serious negative effects you should seek medical attention immediately. Additionally viagra can communicate with other medications so always speak along with your doctor before starting any new medications or treatments for ED including viagra.
