Vigora Oral Jelly is a formulation marketed for the treatment of erectile dysfunction (ED). It commonly contains sildenafil, a phosphodiesterase type-5 (PDE5) inhibitor. Sildenafil works by supporting the natural mechanism that increases blood flow to the penis during sexual stimulation. When a man becomes sexually aroused, nitric oxide is released in penile tissue. This activates a pathway that increases cyclic guanosine monophosphate (cGMP), causing the smooth muscles in penile blood vessels to relax. Sildenafil inhibits PDE5, the enzyme responsible for breaking down cGMP.
