Phosphodiesterase type 5 inhibitors (PDE5 inhibitor) are oral medications used to block degradative action in the smooth muscle cells lining the blood vessels. These oral drugs increase the release of nitric oxide, that assist in the dilation of arteries, which results in an increased blood flow into the penis. One thing to be noted here is that these drugs don’t cause sexual stimulation directly rather potentiate the sexual excitement and cause erections to become harder than before.
“A great place to start for men over 30” says Dr. Wood of Louisville Men’s Clinic,“Ideally, taking a pill that 45 min later causes an erection is the outcome we want for everyone. Unfortunately, it’s not one-size fits-all and we have to take the good with the bad.
