Erectile dysfunction drugs have become quite common over the past decade and it's hard to surprise anyone by telling them that there are medications for male impotence available on the market. Being one of the least pleasant conditions mainly due to the inability to address it effectively, male impotence has rapidly become just another conditions that needs a simple pill to get over. People are used to using ED pills and the whole topic of male impotence has shifted from being a taboo to a simple health problem just like arthritis or diabetes. Yet, a lot of people these days still don't realize how exactly the ED pills they use on a regular basis help eliminate erectile problems. If you too are inquisitive about the mechanism of action behind modern ED treatments you will certainly find this short overview educating.

First of all you should understand that all the drugs that have been officially approved by the FDA as treatments for erectile dysfunction make part of the same drug class and share the same mechanism of action. So it really doesn't matter whether you're using Cialis or any other medication - the effects ...
... are the same, and only the extent of these varies depending on the drug and dosage being consumed. The class of drugs Cialis, Viagra and Levitra make part of is called PDE-5 inhibitors and the name contains a partial explanation of the mechanism of action behind all these drugs.

PDE-5 inhibitors work by blocking a specific enzyme called PDE-5, which is responsible for regulating the blood flow in and out of the penis during erection. When an erection is formed the more blood flows into the penile shaft the stronger the erection will be. And the longer the blood stays inside the cavernous bodies of the penis the more durable the erection is. Normally, the PDE-5 enzyme starts affecting blood circulation after ejaculation, evacuating blood from the penis. However, under different circumstances that affect blood circulation in general, such as hypertension, diabetes, obesity, heart diseases and other conditions that are known as the most common causes for ED, the enzyme starts working too soon, preventing proper accumulation of blood in the penis during the initial stage of erection and promoting faster out flow of blood later on. This is manifested through weak and unstable erections that are the main symptom of male impotence.

So when you take a pill of Cialis or any other similar drug the blood flow to the penis is intensified due to PDE-5 inhibition and the blood tends to stay in the penile shaft for as long as you want it to be there. This simple yet highly effective mechanism of action has proven to be quite efficient in the majority of ED cases. Because blood circulation problems are known as the primary cause for male impotence to develop, this mechanism of action allows improving the quality of erection in most men using these medications. And that would account millions and millions of men all over the world who are happy to enjoy intimacy once again by simply taking prescription pills on a regular basis.
