Levitra without Prescription

Erectile dysfunction is a very distressing condition that can affect all aspects of a man’s life; it can affect self-confidence and intimate relationships in a negative manner. Men who suffer from erectile dysfunction often develop low self-esteem and can even withdraw from their partner due to this condition. For these men, the chance to buy Levitra no prescription needed for the family doctor, can be a real relief. Erections occur in men when they are sexually aroused. The sexual arousal can occur either visually or through physical stimulation. When sexual arousal occurs, the blood vessels and arteries leading into the penis become dilated causing a surge of blood into the penis. When blood surges into the penis the fleshy muscular tissue becomes engorged and stiff. Erections usually last as long as the man is aroused or has an ejaculation. When men cannot obtain erections it is because the blood flow into the penis is restricted. The enzyme phosphodiesterase type 5 is responsible for this restriction of blood flow since it acts as a vasoconstrictor. This enzyme is only active during sexual arousal and causes the blood vessels and arteries leading into the penis to contract and constrict. When the blood vessels are constricted erections cannot occur.
Levitra how it works is that it is a PDE5 inhibitor and prevents this enzyme from being activated. When this enzyme is deactivated it cannot constrict the blood vessels and arteries that lead into the penis. When PDE5 is inactive the blood vessels can fully dilate during sexual arousal and long lasting erections can be achieved. The erections can last several hours from 2 to 4 and they subside when sexual arousal stops or the man has ejaculated. The medication only works during sexual arousal since PDE5, which it is formulated to inhibit, only occurs during sexual arousal. This medication has to be taken half an hour before sexual activity takes place. It takes the Levitra this long to break down chemically in the body and become assimilated in the blood stream.
