After taking this drug, it works by inhibiting the enzyme phosphodiesterase type V, which is relatively high in the penile tissue and can indirectly increase the level of guanosine cyclic phosphate in the body. It can relax the smooth muscle of the cavernous body of the penis and increase the blood perfusion of the cavernous body, thus promoting the effect of erection, which generally lasts for about 2 to 4 hours after taking the drug. Will long-term use of Viagra be addictive? According to the relevant authorities, Viagra is also a neurological drug, but it is not as dependent as some drugs that affect the nerves, so the statement that taking Viagra can be dependent is inaccurate, but the frequent use of type V phosphodiesterase inhibitors will lead to a lack of guanylate cyclase levels in the penile corpus cavernosum, when not using type V phosphodiesterase inhibitors, the level of guanylate cyclase in the corpus cavernosum The lower the level of guanylate cyclase in the corpus cavernosum, the more difficult the erection dilemma. Many people say that taking Viagra can create a sense of dependence, but it is more of a psychological dependence, so if you want to really treat this drug properly, it is best to take it as prescribed by your doctor.
