Vidalista’s effectiveness in treating erectile dysfunction (ED) is rooted in its active ingredient, tadalafil, which functions as a phosphodiesterase type 5 (PDE5) inhibitor. By blocking PDE5, tadalafil prevents the breakdown of cyclic guanosine monophosphate (cGMP), a molecule crucial for relaxing smooth muscles and dilating blood vessels in the penis. This mechanism enhances blood flow and facilitates a firm erection during sexual arousal. Vidalista 20mg stands out due to its extended duration of action, lasting up to 36 hours, which offers greater flexibility compared to other ED medications. Its absorption and metabolism, primarily in the liver, contribute to its prolonged effects, making it a reliable choice for men seeking both spontaneity and consistent results.
