Sildenafil and vardenafil inhibit PDE6, an enzyme found in the eye, more than tadalafil. Some sildenafil users see a bluish tinge and have a heightened sensitivity to light because of PDE6 inhibition. Sildenafil and vardenafil also inhibit PDE1 more than tadalafil. PDE1 is found in the brain, heart, and vascular smooth muscle. It is thought that the inhibition of PDE1 by sildenafil and vardenafil leads to vasodilation, flushing, and tachycardia.

Penile erection during sexual stimulation is caused by increased penile blood flow resulting from the relaxation of penile arteries and the smooth muscle of the corpus cavernosum. This response is mediated by the release of nitric oxide NO from nerve terminals and endothelial cells, which stimulates the synthesis of cGMP in smooth muscle cells. Cyclic GMP relaxes smooth muscle and increases blood flow to the corpus cavernosum. Tadalafil and sildenafil and vardenafil inhibits PDE5, however, because sexual stimulation is required...

Food and Drug Administration found that tadalafil along with other PDE5 inhibitors was associated with vision impairment related to NAION non-arteritic anterior ischemic optic neuropathy in certain patients taking these drugs in the post-marketing outside of clinical trials setting. Given the small number of NAION events with PDE5 use fewer than one in one million , the large number of users of PDE5 inhibitors millions and the fact that this event occurs in a similar population to those who do not take these medicines, the FDA concluded that they were not able to draw a cause and effect relationship, given these patients underlying vascular risk factors or anatomical defects. However, the label of all three PDE5 inhibitors was changed to alert clinicians to a possible association. In October , 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...

Tadalafil is a drug available on prescription prescribed for men with erectile dysfunction resulting from certain medical conditions. Tadalafil is also prescribed for men with prostate gland enlargement. The prostate gland commonly becomes larger in older men. The condition is also called benign prostatic hyperplasia BPH.
