AbstractTadalafil, a member of the cGMP-specific phosphodiesterase type 5 inhibitors, is known to inhibit the phosphodiesterase type 5 enzyme. The effect of tadalafil on human nitric oxide synthase (hNOS) was investigated using human aortic rings, isolated from male rats. hNOS was inhibited by the addition of the phosphodiesterase inhibitor (PDEI) to the medium, and by the addition of a second phosphodiesterase inhibitor (PDEI) in the medium. The inhibition of hNOS was not due to a decrease in the number of nitric oxide synthase-containing cells, but due to a decrease in the levels of nitric oxide synthase. Inhibitors of phosphodiesterase type 5, including sildenafil, reduced the amount of cGMP and increased the level of cGMP-specific phosphodiesterase. It appears that the phosphodiesterase type 5 enzyme is the predominant intracellular enzyme in the human aortic rings.
