Viagra
and Generic Viagra (Sildenafil citrate) is a prescription
drug that first became available in 1998 by Pfizer, Inc. As most
people know, Viagra is commonly prescribed for erectile dysfunction,
otherwise known as ED.
Dysfunction sounds bad, but we have all had trouble getting an erection at one time or another! Stress, diet, age, fitness, and other modern factors can affect a man's libido and ability to stay hard for extended periods of time. There are a lot of things you can do to help yourself keep the ability to get hard and have an erection: fitness, rest, diet, and lifestyle. Erectile Dysfunction drugs won't make you have an erection if you can't already get one, and you can't use it to prevent premature ejaculation or make your penis larger.
Basically, Sildenafil, Cialis, Levitra, Vardenafil all work by changing your blood chemistry to constrict the veins that carry blood away from the penis. More blood stays in the penis, making the erection fuller and harder.
In a non-erect state, the arteries that bring blood into the penis are somewhat constricted, while the veins that drain the blood from the penis are open. There is no way for pressure to build inside the penis.
In this state, the penis is limp. When a man becomes aroused, the arteries leading into the penis open up so that pressurized blood can enter the penis quickly. The veins leaving the penis constrict. Pressurized blood is trapped in the penis, and this blood causes the penis to elongate and stiffen.If the arteries leading to the penis do not open up properly, it is difficult or impossible for a man to become erect. This problem is the leading cause of erectile dysfunction, and can be remedied with the drugs in the Viagra Sample Pack.
