Sildenafil, widely known as Viagra®, is a medication used to treat erectile dysfunction. It was the first commercialized selective phosphodiesterase type 5 (PDE-5) inhibitor and was immediately popular both for treating erectile dysfunction and for recreational use. Sildenafil works by binding to phosphodiesterase type-5 enzymes, competing with the natural ligand cyclic guanine monophosphate (cGMP), which is structurally similar to sildenafil. Vardenafil, a newer and more potent PDE-5 inhibitor, is nearly identical to sildenafil, while tadalafil is considerably different in structure.
