Текст сообщения: | In 1992, Pfizer filed a patent covering the substance sildenafil and its use to treat cardiovascular diseases.[67] This would be marketed as Revatio. The patent was published in 1993 and expired in 2012. The patent on Revatio (indicated for pulmonary arterial hypertension rather than erectile dysfunction) expired in late 2012. Generic versions of this low-dose form of sildenafil have been available in the U.S. from a number of manufacturers, including Greenstone, Mylan, and Watson, since early 2013.[68] Health care providers may prescribe generic sildenafil for erectile dysfunction.[65] However, the generic is not available in the same dosages as branded Viagra, so using dosages typically required for treating ED requires patients to take multiple pills.[65] [url=http://huthtechnologies.com/wp-source/how-do-i-get-a-prescription-for-antabuse.html]how do i get a prescription for antabuse[/url] 9 Society and culture [url=http://huthtechnologies.com/wp-source/order-topamax-from-canada.html]order topamax from canada[/url] Sildenafil Sildenafil structure.svg [url=http://huthtechnologies.com/wp-source/is-generic-propecia-as-good-as-the-real-thing.html]is generic propecia as good as the real thing[/url] Care should be exercised by people who are also taking protease inhibitors for the treatment of HIV infection. Protease inhibitors inhibit the metabolism of sildenafil, effectively multiplying the plasma levels of sildenafil, increasing the incidence and severity of side effects. Those using protease inhibitors are recommended to limit their use of sildenafil to no more than one 25 mg dose every 48 hours.[2] Other drugs that interfere with the metabolism of sildenafil include erythromycin and cimetidine, both of which can also lead to prolonged plasma half-life levels.
