as the tertiary impotence prescription drug after sildenafil ( Viagra ) and levitra ( Levitra ). Soon, in 1994, ICOS received sildenafil cialis generico a patent for compound IC351 (structurally unlike sildenafil and vardenafil), and Phase 1 clinical trials began in 1995. .
Although sildenafil (Viagra) and vardenafi (Levitra), and tadalafil (Cialis) all work by inhibiting PDE5, tadalafil's pharmacologic distinction is its longer half-life (17. .

Using organic nitrites (such as the sex drug amyl nitrite) within this timeframe may increase the risk of life-threatening hypotension. These side effects reflect sildenafil cialis generico the ability of PDE5 inhibition to vasodilate (cause blood vessels to widen) and usually go away after a few hours. In October 2007, the FDA announced that the labeling for all PDE5 inhibitors, including tadalafil, requires a more prominent warning of the potential risk of sudden hearing loss as the result of postmarketing reports of deafness associated with use of PDE5 inhibitors.
