PDE5 Inhibitor Drugs — What Are They?

April 21st, 2014

If you search the internet you may find a lot of drugs which are called PDE5 inhibitor, such as Viagra and Cialis. PDE5 inhibitors are types of medicines used to help men conquer the symptoms of erectile dysfunction. A lot of doctors worldwide might prescribe you with these kinds of medications if you have been diagnosed positive of ED. There are many drugs, both brand-names and generic, that you may avail today. Each may have different features and length of effectiveness but all have one same and common goal – to treat the symptoms of erection difficulties.

What is erectile dysfunction anyway? Erectile dysfunction, or commonly known for its short abbreviation ED, is a medical disorder characterized with a man’s inability to perform proper erection of the penis. Although it may not sound so dangerous or fatal, having ED symptoms can do harm not only in the personal life of a man but also in his overall health as well. The disorder is very frustrating that it can lead to emotional and psychological problems, eventually leading to break ups of relationships, low self-esteem, unproductive professional life, and many others. Recently, there are no accurate methods to completely prevent the onset of the symptoms, especially since the major problems originate with hormonal imbalances.

So how does ED occurs? Normally, when a man feels sexually excited his brain starts sending signals to some parts of the body to produce nitric oxide. Nitric oxide is an important substance in the body in order for the blood vessels to perform contraction and expansion. When the substance can be seen floating around your blood stream, the smooth muscles or blood vessels starts to expand so that more blood can flow towards the penile region. Then the muscles contract in order to trap or accumulate the blood. This is why a man is able to perform erection. However, some enzymes called the phosphodiesterase of type 5 can halt the chain of reactions as they start to break down the nitric oxide in the blood stream. When this happens, the smooth muscles return to their normal state, causing the failure of performing erection. This leads to frustration for both partners.

How does PDE5 inhibitors work? From the name alone, we can conclude that the major function of this drug is basically to halt or inhibit the activities of the PDE5 enzymes. This prevents them from breaking down the nitric oxide which is the main factor to perform normal erection. With the process being undistracted, the normal chain of reaction continues and as long as the drug is in effect, a man can have erection as long as he is sexually stimulated. But remember that pde5 inhibitor medicines will not be able to help you if you do not feel sexually aroused.

Despite of the promising benefits of pde5 inhibitor drugs, remember that this medicine may not be for everyone to use. For some people there might be contraindications. If you think you have ED problems, it is better that you consult first with your doctor before you use pde5 inhibitor medications.
