A medicine called Vidalista 40 is intended to treat erectile dysfunction, which is a prevalent issue for males. It contains tadalafil, a member of the phosphodiesterase type 5 inhibitor medication class. In a nutshell, Vidalista 40 facilitates more blood flow by relaxing the penile blood arteries. When sexual stimulation takes place, this helps to achieve and sustain an erection. Vidalista 40 has a longer duration of action, up to 36 hours, in contrast to other medicines in its class. Because of its prolonged period of efficacy, it has been dubbed "the weekend pill."
