PDE5 Inhibitors work by increasing the effects of nitric oxide (NO). A chemical that the body naturally releases when it is s*xually aroused or when it is doing certain bodily processes.
Cyclic guanosine monophosphate (cGMP) is made when nitric oxide is present. cGMP softens smooth muscle tissue and improves blood flow.
In ED, blocking PDE5 stops cGMP from breaking down. This keeps blood flowing to the p*nis, which helps get an erection when s*xually aroused.
When someone has PAH, more blood flow to the lungs helps ease symptoms like shortness of breath. Vardenafil Levitra are common choices. Levitra is known for starting to work quickly.
