    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. 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.

    The Narcotic Drugs and Psychotropic Substances Bill, 1985 was introduced in the Lok Sabha on 23 August 1985. It was passed by both the Houses of Parliament and it was assented by the President on 16 September 1985. It came into force on 14 November 1985 as THE NARCOTIC DRUGS AND PSYCHOTROPIC SUBSTANCES ACT, 1985 (shortened to NDPS Act). Under the NDPS Act, it is illegal for a person to produce/manufacture/cultivate, possess, sell, purchase, transport, store, and/or consume any narcotic drug or psychotropic substance. Under one of the provisions of the act, the Narcotics Control Bureau was set up with effect from March 1986. The Act is designed to fulfill India's treaty obligations under the Single Convention on Narcotic Drugs, Convention on Psychotropic Substances, and United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances. The Act has been amended three times - in 1988, 2001, and most recently in 2014. Can you buy benzos such as Valiums and Xanax in New Delhi or.
