The mammoth like existence of the disease called erection dysfunction and its omnipresence has forced and triggered a number of studies and researches into the disease, especially after the invention of the very famous ED drugs about a decade ago. Though even prior to the invention of the oral ED pills ED medications existed they were more often than not ineffective. Today however times have changed and there are as effective ED treatments as the oral drugs, albeit a little complicated. There are many people who are not tolerant to any of the ED pills, not even to canadian viagra pro which is touted to be the safest among the three, for them these ED treatments can be of great use. The ED drugs basically work by preventing the breakdown of a chemical called cGMP which triggers erection. All the famous ED drugs contain phosphodiesterase-5 (PDE-5) inhibitors. This is the chemical that prevents the breakdown of cGMP.

Though ED is now fairly defeated by medical science, still researches into the disease continue in order to know the disease better. This will in turn enable mankind to invent better and safer and a larger variety of ED drugs. In a similar study conducted recently, it was found that caffeine can be helpful in boosting up erection functions in men. The study was actually conducted on rats and the results were very encouraging. However, whether caffeine will be of help to the men with ED is still to be proved. Another factor that comes in is that the researchers who conducted the study have said that caffeine can be especially of help to those men who are victimized by ED due to diabetes. The chances of caffeine helping men with diabetes induced ED is however not as much as in the men who have ED without diabetes. Diabetes is a very fertile cause of ED. Though it is unbelievable it is absolutely true that almost 75% of diabetics are troubled by ED.

The fact that other elements like caffeine, apart from the ED drugs can be helpful in ED treatment is indeed heartening news. However, this does not imply that diabetic men with ED can cure the latter by sipping down buckets of coffee. It has not been proved that caffeine is capable of curing ED completely on its own. Yes, it has been claimed that in case a diabetic men with ED has more than required dose of caffeine he will need to have a less than required dose of medicine. Apart from this the exact degree of effects of having caffeine is still to be determined. The ED drugs work by preventing the breakdown of cGMP in the penis, where as caffeine does the task in the entire body. Among the ED medications as I have already mentioned levitra is often advertised to be safe for the people with heart ailments and diabetes. People actually tend to buy viagra professional because of this plus point. Inspite of these plus points one should never forget the viagra pro dangers that can ensue if the drug is had without prescription. There are certain canadian online pharmacies that claim to sell ED drugs without prescription. One should always beware of such pharmacies. Even in the case of viagra professional always ensure that you are given a prescription when you buy viagra professional online.

A basic science breakthrough by Queen’s researchers into regulating a single enzyme may lead to new drug therapies that will help prevent heart attacks and strokes.

Led by professor of Pharmacology and Toxicology Donald Maurice, the study focuses on the effects of Viagra – the popular erectile dysfunction drug, which is also used to treat pulmonary hypertension.

“As scientists, we’re excited about this discovery because it’s a fundamentally new approach to regulating what enzymes do in cells,” says Dr. Maurice, a Career Scientist with the Ontario Heart and Stroke Foundation. “The fact that it also offers a potentially novel use of a drug already widely in use for other applications is an unexpected bonus.”

The enzyme targeted by the Queen’s researchers is known to regulate the activity of platelets: small blood cells needed for normal blood clotting. Problems can arise when people have stents permanently implanted in their arteries to maintain blood flow. Their platelets sometimes bind to the stent and, if enough platelets accumulate to form a blockage, this may cause a sudden, massive heart attack or stroke to occur.

Drugs like Viagra Pro have been shown to inhibit PDE5, explains Lindsay Wilson, a PhD student in Pathology and Molecular Medicine and first author on the study. Until now, however, it hasn’t been possible to isolate the small “pool” of activity within the cell where this is occurring.

The Queen’s study shows that within each cell there are two different pools of the PDE5 enzyme, but that only one of them regulates platelet activation. “Understanding how the cell works should allow us to affect the activity of enzymes in one neighborhood – and leave alone their ‘identical twins’ in a different neighborhood in that cell,” says Ms Wilson.

“The idea is to use a PDE5 inhibitor such as canadian Viagra Pro selectively to inhibit platelet function,” she continues. We now know that not all the enzymes in the cell are doing the same job. Just like in real estate, it’s all about the location!”

The team’s findings were recently published online in the international journal Proceedings of the National Academy of Sciences. Other members of the Queen’s research team are Hisham Elbatarny and Brian Bennett (Pharmacology and Toxicology), and Scott Crawley (Biochemistry). Funding came from the Ontario Heart and Stroke Foundation and the Canadian Institutes of Health Research (CIHR).
