The lives of many men in the world changed fundamentally in 1998, when by the American company Pfizer first Sildenafil citrate was synthesized, an active substance which is capable of stimulating blood flow to penis and ensuring stable erection. Of course, when at Canadian pharmacy Viagra appeared it helped many men to forget about impotence and to improve their sexual performance. Soon after launching Viagra on the market the range of medicines for treating erectile dysfunction was widened by several effective drugs based on other synthetic substances. At Canadian pharmacy Cialis and Levitra were represented having almost the same mechanism of action as Viagra. And then the development of generics made these drugs affordable for million men worldwide. Acting the same way as expensive branded medications generics are much cheaper though their quality is as good as original drugs have.
But does this mean that impotence is beaten totally? Unfortunately, there can be a lot of different causes of erectile dysfunction and the medicines based on synthetic substances help only in a limited number of cases. Mainly with the help of generics it is possible to improve erection when its decreasing refers to psychological problems or vascular disorders. In addition, generics work well only when a man feels sexual arousal, but they do not increase libido. Luckily, there are medicines that can both improve potency or increase libido – drugs based on herbs also called Herbal Viagra.
