Canadian Pharmacy Levitra is a medication type that belongs to the class of phosphodiesterase type 5 inhibitors and is widely used for the treatment of male impotence. Small pills are really effective in helping men to achieve penile erection needed for sexual activity. How is it possible? The medication allows a comparatively greater blood flow to the penis, if a man is sexually aroused (Levitra works only with the sexual stimulation, but cannot increase sexual desire).
Why can’t it work without stimulation? The answer is pretty clear: those chemicals that trigger erection can be released only if a man is aroused. The medication itself does not have any effect on the chemicals being released. Everything it can do is keeping these chemicals in the penis longer.
