Vidalista 20 is a medication that contains tadalafil, which is a phosphodiesterase type 5 (PDE5) inhibitor. It is primarily prescribed for the treatment of erectile dysfunction (ED) in men. When taken orally, Vidalista 20 works by increasing blood flow to the penis, thereby helping to achieve and maintain an erection.
The mechanism of action of Buy Vidalista 20 involves the inhibition of the PDE5 enzyme. This enzyme is responsible for breaking down cyclic guanosine monophosphate (cGMP), which is a chemical messenger that plays a crucial role in the erectile response. By inhibiting PDE5, Vidalista 20 allows cGMP to accumulate and remain active for a longer duration.
During sexual arousal, the release of nitric oxide (NO) in the penis triggers the production of cGMP. This cGMP relaxes the smooth muscles of the penile blood vessels, leading to vasodilation and increased blood flow to the erectile tissues. As a result, the penis becomes engorged with blood, resulting in an erection.
