PDE5 is an enzyme found in several tissues, including your blood vessels, lungs, intestines and eyes. It is found in particularly high concentrations in the smooth muscle cells lining the blood vessels of your penis. PDE5 breaks down a molecule called c GMP, thereby reducing your cells’ ability to produce nitric oxide. Nitric oxide promotes blood vessel dilation, which enhances blood flow to the penis and improves erectile function. By blocking PDE5, Levitra increases c GMP levels, boosts nitric oxide production and strengthens erections. Like many drugs, Levitra is partially metabolized by a specific enzyme, called CYP3A4, in the lining of your intestine. can you buy viagra in argentina Vardenafil can lower blood pressure, and combining it with ethanol may further increase this effect.
