Learn about Erectile Dysfunction and Sildenafil Citrate Online

Have you ever wondered how sildenafil acts within your body to help you solve your problems with erectile dysfunction?  Thanks to the instant availability of the Internet and computer devices, you will now be able to learn about ED and sildenafil citrate online right at your fingertips.

If you are curious as to how PDE5 inhibitors such as sildenafil work inside your body, then you can browse on search engines by simply typing in the search box the words sildenafil citrate online.  When you read about the mechanics of the action of sildenafil citrate online, you will learn that it helps protect the enzyme cGMP (short for cyclic guanosine monophosphate) from being degraded by the cGMP-specific PDE5 (short for phosphodiesterase type 5 enzyme) which are evidently located in the penile corpus cavernosum of men.  The free radical NO (short for nitric oxide) found in the penile corpus cavernosum adheres itself to what are called the guanylate cyclase receptors, which then results to the occurrence of elevated amounts of cGMP, thereby leading to the vasodilation or relaxation of the smooth muscles of the inner lining cushions of the helicine arteries (tendril-like arteries of the penis importantly involved in the process of its erection).  Once the smooth muscles relax, it will result to vasodilation and therefore there will be an increased supply of blood flowing into the penile spongy tissue, and the end result would be a successful penile erection.

Additionally, what you would also learn about sildenafil citrate online is that its special molecular makeup is somewhat similar to cGMP (located in the penile corpus cavernosum as well) and functions as an aggressive binding element of PDE5 in the penile corpus cavernosum, which results to more concentrations of cGMP and even better occurrences of erections. Avery important information that men will learn through reading about sildenafil citrate online is that sildenafil will be rendered useless without the introduction of one or more sexual stimuli, since only a sexual stimulus will be the only factor that can initiate the activation of the nitric oxide and cGMP inside a man’s body.

Codeine article ruffles feathers

Our article on a rare case of fatal neonate codeine poisoning ("") has a group called - who promote something called Family Medicine from a Biblical World View - all fired up.

On their , the group takes exception to the idea that women should take any meds after childbirth. They also don't seem to like the idea of physicians using their clinical judgement to decide which women could safely use Tylenol 3 for post-partum pain relief:

The “experts”, as they call themselves, disagree with this mother. One of their suggestions, according to the article I cited, is for nursing mothers to continue to take the deadly Tylenol 3, and keep an eye on mom and baby.

Instead, APM Formulators urge parents to "protect yourself through the knowledge of medicinal plants that have properties for after birth pain."

One has to wonder whether the good people at APM Formulators are aware that is one of those "medicinal plants that have properties for after birth pain."

Canadian Medicine writ large

There’s never been a better time to dissect our healthcare system.

, Michael Moore’s new documentary on the state of healthcare (released today in Canada), holds us up as a model of how well universal healthcare can work. Many Canadians will experience a mix of pride and incredulity when they see it (I know I did when I saw it). But what’s certain is that seeing our system on the big screen is making us all do a little healthcare soul searching.

So we think it’s a great time for us to launch our new editors’ blog.

Every week we'll post the health stories - Canadian and international - we think are important, shocking or just just plain odd. We'll also bring you updates on stories we’ve covered in the .

We hope you enjoy it.

Happy Canada Day!
