This promotes blood vessel expansion and increases blood flow to the penis during sexual stimulation. In this manner, an erection can be sustained. Consume the drug while drinking a glass of water. Never break or chew the prescription drug. After dissolving the drug in a glass of water, take it immediately. On the other hand, both treatments work best when taken on an empty stomach.
