    Sildenafil history


    A generic version of Viagra will be available on Monday (Dec. 11), and it will cost half the price of the "little blue pill." Pfizer, which makes Viagra, will produce its own generic version of the drug, which contains the active ingredient sildenafil, according to the Associated Press. The generic will be white rather than blue, and it will cost around $32 a pill, half Viagra's price. By selling its own generic version, Pfizer will be able to compete with other drug companies that can start selling sildenafil as soon as Monday, when Pfizer's patent on the drug expires, the AP said. Here are five interesting facts about Viagra (sildenafil): When researchers first created sildenafil in the 1980s, it was intended to be a treatment for angina, or chest pain caused by reduced blood flow to the heart, according to a 2004 review article. However, in an early trial, the drug did not produce the heart effects the researchers had hoped for. But a number of study volunteers reported an interesting side effect — they had stronger and more persistent erections. propranolol 80 mg side effects The NICE British National Formulary (BNF) and British National Formulary for Children (BNFc) sites are only available to users in the UK, Crown Dependencies and British Overseas Territories.

    In fact, the history of creation of Viagra is quite curious. Literally, an amazing remedy for erectile dysfunction appeared accidentally. Initially, scientists tried to invent a medicine that will cure people with serious heart diseases. On the other hand, Viagra is not the first drug with an unexpected effectiveness. Maybe you remember that once approximately the same happened with antibiotics. Almost a century ago in Britain a mold was found, which quickly and easily destroyed different types of bacteria. Researchers studied the properties of that mold, and discovered penicillin. Impotence treatments are, in a sense, nothing new – they have been around at least as long there have been medical texts to testify about their existence. Yet, their effectiveness is a completely different story altogether. Throughout much of history, ED treatments were found in the shape of herbal remedies, spells and magic amulets, so one can say their effectiveness was… Once medicine progressed enough to recognize that supernatural forces don’t have much interest in ordinary man’s erectile dysfunction, medical experts of the time turned to other causes. But, even then, the root cause of ED problems was assumed to be rooted in psychological issues, not physiology. It sounds odd from this perspective, but it was only in the late 1980s and early 1990s that scientists actually got interested in searching for physiological causes of impotence. The story of Viagra, at least in a stricter sense, starts in the 1990s in the picturesque little town of Sandwich, Kent, in a Pfizer’s research facility that was determined to develop a new pharmaceutical compound that could treat hypertension and angina pectoris, while preventing blood clots. Once a safe and seemingly suitable substance named sildenafil (originally, compound UK/92,480) was discovered, Ian Osterloh, a British clinical researcher employed at Pfizer decided to begin the first phase of clinical trials in Morriston Hospital in Swansea, Wales. At first, the results were discouraging since effects sildenafil had on angina were negligible.

    A hot, humid, tropical environment and prolonged use of occlusive footwear are the most common risk factors for all types of tinea pedis. The prevalence of tinea pedis increases with age and it is rare during childhood.4 There are different clinical variations of tinea pedis. This presentation is characterized by chronic plantar erythema with slight scaling to diffuse hyperkeratosis. This presentation is marked by painful, pruritic vesicles or bullae, most often on the instep or anterior plantar surface. Swimming and communal bathing may also increase the risk of infection.1,2 Tinea pedis is the most common dermatophytosis worldwide with 70 percent of the population infected at some time.3 Tinea pedis is not associated with significant mortality or morbidity. They include interdigital, chronic hyperkeratotic, inflammatory/vesicular and ulcerative tinea pedis. This is one of the most characteristic types of tinea pedis with erythema, maceration, fissuring and scaling. The lesions can contain either clear or purulent fluid. This is characterized by rapidly spreading vesiculopustular lesions, ulcers and erosions, typically in the interdigital spaces, and is usually associated with a secondary bacterial infection. Cellulitis, lymphangitis, pyrexia and malaise are usually associated with this infection. This type is commonly present in immunocompromised patients and those with diabetes. One can diagnose tinea pedis using potassium hydroxide (KOH) staining for fungal elements. The infection is easily visible under the microscope. Treatment usually consists of topical antifungals, oral antifungals or a combination of both. Untreated tinea pedis can lead to secondary cellulitis, lymphangitis, pyoderma and osteomyelitis. The type of tinea pedis infection and underlying conditions affect the prognosis but with appropriate treatment, the prognosis is good.
