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.

Relistor may weaken the GI wall

When to beware

As all meds do, mythylnaltrexone bromide (Relistor) has its share of possible side effects, the most common being dizziness, flatulence, mild diarrhea, nausea, stomach pain, vomiting, and hyperhidrosis. Severe reactions include a serious case of any already mentioned, or allergic reactions.

Today, Health Canada and Wyeth Canada added a new possible adverse reaction to the list: a heightened risk of gastrointestinal perforation, especially in those with GI cancers and other conditions that could weaken the gastrointestinal wall.

When Relistor came onto the scene – it was approved by Health Canada on March 28, 2008 – it relieved opioid-induced constipation in palliative-care patients with incurable cancers, end-stage COPD from emphysema, heart failure, Alzheimer’s disease, and so on, when other laxative therapies could not – in under 30 minutes. Administered by subcutaneous injection, it blocks opioids from entering cells, allowing bowels to revert to normal function, while not interfering with the opioid’s ability to relieve pain.

The current warning advises discontinuing Relistor and seeking professional help if severe, persistent symptoms like abdominal pain intensified by movement, nausea and vomiting -- possibly accompanied by fever and chills – worsen, as these can be signs of GI perforation.

It makes one wonder, though, if the original studies on this drug should have lasted a wee bit longer than four months.
