? ? ? ? ? ? ? ? Male Enhancement Sildenafil Citrate (Viagra) Raw Powder / Strong Effect
?
?
Description:
?
Sildenafil citrate is the raw material of Viagra, viagra treats erectile dys function and
?
works by relaxing muscles and increases blood flow to particular areas of the body (in this
?
case, the penis, specifically). Its effects last up to four hours. The most common side
?
effects of Viagra are headache, facial flushing, and upset stomach. Rarely, blurred vision,
?
or sensitivity to light may briefly occur.
?
?
As well as treating impotence, Sildenafil Citrate can also be effective in treating Pulmonary
?
Arterial Hypertension (PAH). Similarly to how it acts to relax muscles of the penis, it
?
relaxes arterial walls; therefore, reducing resistance and pressure in the arteries.
?
?
Sildenafil Citrate is solely active in relaxing muscles and increasing blood flow to the
?
heart, lungs and penis due to PDE-5, yet vasodilation is not increased in other parts of the
?
body.

?
Application:
?
Sildenafil citrate, sold as Viagra, Revatio and under various other trade names, is a drug
?
used to treat erectile dysfunction and pulmonary arterial hypertension (PAH).
?
used in the treatment of penile erectile dysfunction (ED).
?
?
The primary indication of sildenafil is treatment of erectile dysfunction (inability to
?
sustain a satisfactory erection to complete intercourse). Its use is now standard treatment
?
for erectile dysfunction in all settings, including diabetes.
?
?
People on antidepressants may experience sexual dysfunction, either as a result of their
?
illness or as a result of their treatment.
?
?
Mechanism Of Action:
?
The physiologic mechanism of erection of the penis involves release of nitric oxide (NO) in the
?
corpus cavernosum during sexual stimulation. NO then activates the enzyme guanylate cyclase,
?
which results in increased levels of cyclic guanosine monophosphate (cGMP), producing smooth
?
muscle relaxation in the corpus cavernosum and allowing inflow of blood.
?
?
Sildenafil enhances the effect of NO by inhibiting phosphodiesterase type 5 (PDE5), which is
?
responsible for degradation of cGMP in the corpus cavernosum. Sildenafil has no direct relaxant
?
effect on isolated human corpus cavernosum. When sexual stimulation causes local release of
?
NO, inhibition of PDE5 by sildenafil causes increased levels of cGMP in the corpus cavernosum,
?
resulting in smooth muscle relaxation and inflow of blood to the corpus cavernosum. Sildenafil at
?
recommended doses has no effect in the absence of sexual stimulation.
