SHORT ANSWER:It works in treating erectile dysfunction by a complicated medication process.It allows the muscles in the pennis to relax and allows blood to flow in which is the repeated inability to get or keep an erection firm enough for sexual intercourse.
LONG ANSWER:It works similar as viagra and cialis.To understand how Levitra works, it may be helpful to understand erections.All these are (PDE-5) phosphodiesterase-5 drug which works in a same manner.CGMP (cyclic guanosine monophosphate) mediates smooth muscle relaxation.This takes place in the this process and it works by blocking a chemical (PDE5) when this chemical is blocked the chemicals responsible for the erection remain.The muscles in the penis do not constrict. This allows blood to stay in the penis longer.Hence,the erection is maintained.Many men wonder that levitra works without any stimulation but the answer is no.Chemicals that cause an erection are released only when a person is aroused.LEVITRA only keeps the chemicals in the penis longer. Levitra began to work in most men in under an hour. It is generally recommended that you take Levitra an hour before sexual activity.
