A prescription medication called Vidalista 80 is used to treat impotence, often known as erectile dysfunction (ED). A man suffering from impotence is unable to achieve a strong erection because there is insufficient blood flow to the penis. Phosphodiesterase type 5 inhibitor Tadalafil, FDA-approved, is a component of Vidalista 60 (PDE5). Tadalafil works by boosting blood flow to the penile area, which aids in a man's erection. The company Centurion Laboratories produces Vidalista and its several strengths.
