Cialis (tadalafil) ua haujlwm los ntawm inhibiting ib qho enzyme hu uaPhosphodiesterase Hom 5 (PDE5), uas muaj nyob rau hauv cov leeg nqaij leeg ntawm cov hlab ntsha. Ntawm no yog cov ncauj lus kom ntxaws txog nws cov txheej txheem ntawm kev txiav txim:
1. PDE5 thiab Erectile Function
Thaum muaj kev sib deev stimulation, lub cev tawmNitric oxide (NO)nyob rau hauv cov ntaub so ntswg ntawm noov.
Nitric oxide stimulates zus tau tej covCyclic guanosine monophosphate (cGMP), uas relaxes cov leeg du nyob rau hauv cov hlab ntsha phab ntsa.
Kev so ntawm cov leeg no tso cai rau cov ntshav ntws mus rau hauv cov ntaub so ntswg penile, ua rau erection.
PDE5 rhuav tshem cGMP, txo nws cov qib thiab ua rau cov leeg nqaij sib cog lus dua. Qhov no tuaj yeem cuam tshuam lub peev xwm los tuav lub erection.
2. Lub luag haujlwm ntawm Cialis
Cialis thaiv PDE5, tiv thaiv nws los ntawm degrading cGMP.
Raws li qhov tshwm sim, cGMP qib tseem nce siab, txhawb nqa cov leeg du thiab cov ntshav ntws mus rau qhov chaw mos thaum muaj kev sib deev arousal.
Qhov no pab ua kom tiav thiab tswj kom muaj erection thaum sib deev stimulated.
3. Cov teebmeem ntxiv
Cialis kuj txhim kho cov ntshav ntws mus rau lwm qhov ntawm lub cev, xws li prostate thiab zais zis, uas yog vim li cas nws thiaj li raug tshuaj rau benign prostatic hyperplasia (BPH).
Nws tsis ncaj qha induce ib erection; kev sib deev stimulation tseem yuav tsum tau rau nws ua hauj lwm.
Lub Sijhawm Ua Haujlwm
Cialis yog qhov tshwj xeeb ntawm PDE5 inhibitors rau nws lub neej ib nrab ntev, tso cai rau nws cov teebmeem mus ntev36 hnu. Qhov no muab lub qhov rais loj dua rau kev ua plees ua yi piv rau cov tshuaj zoo sib xws xws li sildenafil (Viagra).
