This is not necessarily directly from a plant extract source. Scientists at pharmaceutical companies a systematic study of molecules per million. Some of them were derived from plant sources and others do not. Most of them are changes in the molecules previously studied. You can extract a substance from a plant, analyze its molecular composition, and then find a molecule that is promising and deserves further investigation. Then we could conclude that the molecule is not suitable for some reason, it could slightly change the molecule, then test the new molecule is created, and so on. Literally screening study, and millions of molecules before finding one, that can serve a useful medical application. With computers in this process is much faster than it was.
In the case of Viagra, sildenafil citrate was originally developed to treat ischemic heart disease. In human studies, they found that sildenfil has not shown the promise that he had expected, but they have the gathering of information to patients about side effects, beat her acroß "side effect" of erection in patients with an erection "good" for years. It was decided to investigate further and found it very effective for this purpose. They realized that the erections regulated by an enzyme in the body called phosphodiesterase. Variants of this enzyme is present throughout the body, different things, and are numbered for the purposes of classification. Phosphodiesterase in the penis as PDE5. Other enzymes such as PDE11A is found in skeletal muscle. In short, Swallow prevented PDE5 erectile nitric oxide. Nitric oxide is released during stimulation is an erection, but impotent men have too high a threshold of PDE5 to happen. Viagra, Cialis and Levitra all temporarily inhibiting PDE5, nitrogen oxides, and during arousal and are allowed released, causing an erection. Differences between drugs are at other levels who are disabled PDE. Viagra is also inhibits PDE3 in the eye, color vision, so IU can sometimes be a temporary blue tinge to your vision. Cialis and inhibit PDE11A, which causes a higher incidence of muscle soreness. The drugs also differ in terms of its appearance, and the half life.
