Vidalista 80 mg, like other dosages of Vidalista, contains the active ingredient tadalafil, which is a phosphodiesterase type 5 (PDE5) inhibitor. Understanding the mechanism of action of Vidalista 80 mg is crucial for comprehending how it effectively treats erectile dysfunction (ED).
Relaxation of Blood Vessels: During sexual arousal, the body releases a molecule called nitric oxide. Nitric oxide relaxes the smooth muscles in the walls of blood vessels in the penis. This relaxation allows the blood vessels to widen (vasodilation), leading to increased blood flow into the penile tissues.
Inhibition of PDE5: In individuals with ED, there is an overabundance of an enzyme called phosphodiesterase type 5 (PDE5) in the penile area. PDE5 breaks down cyclic guanosine monophosphate (cGMP), which is responsible for maintaining the relaxation and dilation of blood vessels. When PDE5 is inhibited, cGMP levels increase, prolonging the vasodilation process and enhancing blood flow to the penis.
Enhanced Erection: By inhibiting PDE5, Vidalista 80 mg helps maintain higher levels of cGMP, allowing for a more sustained and improved blood flow to the penis. This results in a firmer and longer-lasting erection that is suitable for sexual activity.
Normalizing Erectile Response: For individuals with ED, the natural physiological response to sexual stimulation is impaired. Vidalista 80 mg helps restore a more normal erectile response by ensuring that the blood vessels in the penis remain dilated and engorged with blood during sexual arousal.
