Vidalista 40mg works by increasing blood flow to the penis, which helps achieve and maintain a firm erection during sexual activity. The active ingredient, Tadalafil, inhibits the enzyme phosphodiesterase type 5 (PDE5), which regulates blood flow in the penis. By blocking PDE5, Vidalista 40 mg enhances the natural process of erection, making it a reliable treatment for ED. One of the standout features of Vidalista 40 mg is its long-lasting action. It can remain effective for up to 36 hours, providing a substantial window for sexual activity without the need for precise timing. This extended duration allows men to engage in sexual activity more spontaneously and reduces the pressure to time medication perfectly, contributing to greater confidence.
