犀利士是一款助勃的神藥,相對於威爾鋼和樂威莊,犀利士的效果是藥效持久,也就是作用時間很長,那麼犀利士的藥理是如何的呢?如何幫助陽痿的男性迅速勃起?
Cialis is a PDE5 agent (Phosphodiesterase type 5 inhibitor). The premise is sexually stimulated: When a man is sexually stimulated, the penis will secrete nitric oxide (Nitric Oxide-NO). GMP in smooth muscle cells is converted into cGMP (changes the permeability of calcium in tissues) and smooth muscle relaxes. After smooth muscle relaxes, blood vessels expand, and then the cavernous body is congested to achieve an erection effect. But the penis will soften after the sexual stimulation disappears!
犀利士是PDE5藥劑 (第五型的磷酸二酯酶抑制劑——Phosphodiesterase type 5 inhibitor)前提受到性刺激:在男性受到性刺激下,陰莖會分泌一氧化氮 (Nitric Oxide——NO)會讓平滑肌的細胞里面GMP 轉化成cGMP(改變組織里面鈣的通透性)平滑肌就會放鬆,平滑肌放鬆後血管就會擴張,然後海綿體充血就達到勃起的效果。但性刺激消失後陰莖會軟掉!
舉個例子:陰莖就是一個老化的氣球,或者有缺陷的氣球,無法吹氣到裡面。因為表皮硬化或者吹氣口被堵住了。而犀利士是一種化學藥物,可以中和氣球表皮使其柔軟富有彈性,也可以疏通堵住的吹氣口,這樣可以吹氣到氣球中,氣球就鼓起來了。陰莖就漲起來,硬起來可以達到做愛的硬度和需求。您明白了嗎?
