    Viagra discovery


    Over the course of your lifetime you are likely to take more than 14,000 tablets - and that is just the prescription medicines. The average person will have taken one course of antibiotics every two years, and 28,000 painkillers. By the time you are 70 you will probably be taking at least five tablets a day. Although we cannot seem to live without them, how much do we really know about the pills we take? We like to think drugs are designed for exact purposes, but they are often not as targeted as we may hope. The surprising truth is drug design owes more to serendipity than careful design, and their potential may only be discovered when we take them. It turns out that Ventolin inhalers, a treatment for asthma, can also prevent premature labour; and arsenic, a notorious poison, is making a come back as a treatment for leukaemia. where to buy tretinoin gel online Are any interesting facts about Viagra history and discovery? Tasked with finding a solution for high blood pressure and angina pectoris, a group of pharmaceutical chemist named Peter Dunn and Albert Wood who worked for Pfizer in England, stumbled upon a solution for a different problem. Even the patent for the drug listed it as a heart pill. During the clinical trials, subjects found that the pill did very little to help with angina, but produced penile erections every time. It was after this discovery that Pfizer stopped developing the pill for angina, and began focusing their efforts on the erectile dysfunction solution that had fallen into their lap. By 1996 Viagra had landed in the USA, and after FDA approval in 1996, Pfizer began marketing “Viagra” or Sildenafil. In its first week after being approved by the FDA, there were 40,00 prescriptions for Viagra. It was made available for sale on March 27, 1998 and has made Viagra history ever since.

    Are any interesting facts about Viagra discovery and history? Viagra (also known by its scientific name sildenafil) is a small little pill that has helped revolutionize the idea of improving sexual performance for men. Outside of a few herbal supplements that have had limited success throughout the years, men, for the most part, simply had to accept their bodies could no longer perform. However, when Viagra came along, it really broke down all sorts of barriers, while giving men back their confidence. But discovering Viagra was more accidental than anything else. As is the case with many essential drugs, researchers were looking for cures on other medical issues yet instead came up with this. For men who are considering the purchase of Viagra or who simply are interested in the history, looking into Viagra discovery is not just informative on the medication itself, but it provides a window of understanding into how the entire pharmaceutical industry works. Pfizer, one of the world’s leaders in pharmaceutical research, had set out to create a medication for treating high blood pressure and chest pain due to heart disease. Like most scientists and clinicians in this field, I chose a career developing drugs in the hope of improving people’s lives. I say ‘hope’, because often pharmaceutical research and development is a source of frustration and disappointment. Certainly, we make a continual contribution to scientific and medical knowledge, but our work doesn’t always yield new medicines. Very few of us get to work on compounds that ultimately benefit patients. In two decades of research, I’ve managed to be in the right place at the right time on more than one occasion. But the development program I’ve had the greatest involvement in concerns one of the world’s most famous drugs. Its scientific name is sildenafil citrate, but it’s better known as Viagra. I first came across the project in the late 1980s, when I learned colleagues at Pfizer’s laboratories in Sandwich, a small town on England’s southeast coast, had come up with a hypothesis about selectively blocking an enzyme called PDE5.

    Last year my doctor prescribed me with Prednisolone to treat my rheumatoid arthritis. Both my knees are badly affected by the disease and it is a real suffering for me to move sometimes, after a long period without movement I can not easily get up and walk. I have to rub my knees, get used to the pain, and wait for the pain to fade away. It takes me about an hour to get out of my bedroom as I have to do many exercises before I stand up and can make first steps. The disease has been torturing me for more than seven years in general. I have tried many different medications - pills, ointments and injections. The effect is either none at all or just minor and temporary. With Prednisolone life got much easier and less painful for me indeed.
